The electronic device (101) may further include a processor (120) and a memory (130). The second network (199) may include a first cellular network (292) and a second cellular network (294). According to another embodiment, the electronic device (101) may further include at least one of the components described in FIG. 1, and the second network (199) may further include at least one other network. According to one embodiment, the first communication processor (212), the second communication processor (214), the first RFIC (222), the second RFIC (224), the fourth RFIC (228), the first RFFE (232), and the second RFFE (234) may form at least a portion of the wireless communication module (192).

[0048] The first communication processor (212) may establish a communication channel in a band to be used for wireless communication with the first cellular network (292), and may support legacy network communication through the established communication channel. According to various embodiments, the first cellular network may be a legacy network including a second generation (2G), 3G, 4G, or long term evolution (LTE) network. The second communication processor (214) may establish a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) among the bands to be used for wireless communication with the second cellular network (294), and may support 5G network communication through the established communication channel. According to various embodiments, the second cellular network (294) may be a 5G network defined by the 3GPP. Additionally, according to one embodiment, the first communication processor (212) or the second communication processor (214) may support establishment of a communication channel corresponding to another designated band (e.g., about 6 GHz or less) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.

[0049] The first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified as being transmitted via the second cellular network (294) may be changed to be transmitted via the first cellular network (292). In this case, the first communication processor (212) can receive the transmission data from the second communication processor (214). For example, the first communication processor (212) can transmit and receive data with the second communication processor (214) via the processor-to-processor interface (213). The above interprocessor interface (213) may be implemented as, for example, a universal asynchronous receiver / transmitter (UART) (e.g., HS-UART (high speed-UART) or PCIe (peripheral component interconnect bus express) interface), but there is no limitation on its type. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information using, for example, a shared memory. The first communication processor (212) may transmit and receive various information, such as sensing information, information on output intensity, and resource block (RB) allocation information, with the second communication processor (214).

[0050] Depending on the implementation, the first communication processor (212) may not be directly connected to the second communication processor (214). In this case, the first communication processor (212) may transmit and receive data with the second communication processor (214) through the processor (120) (e.g., application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data with the processor (120) (e.g., application processor) through an HS-UART interface or a PCIe interface, but there is no limitation on the type of interface. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information with the processor (120) (e.g., application processor) using shared memory.

Upon reception, the RF signal may be acquired from the first cellular network (292) (e.g., a legacy network) via an antenna (e.g., the first antenna module (242)) and preprocessed via an RFFE (e.g., the first RFFE (232)). The first RFIC (222) may convert the preprocessed RF signal into a baseband signal so that it may be processed by the first communication processor (212).

[0054] The second RFIC (224) may, upon transmission, convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 band (e.g., about 6 GHz or less) used in the second cellular network (294) (e.g., a 5G network). Upon reception, the 5G Sub6 RF signal may be acquired from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., the second antenna module (244)) and preprocessed via an RFFE (e.g., the second RFFE (234)). The second RFIC (224) may convert the preprocessed 5G Sub6 RF signal into a baseband signal so that the preprocessed 5G Sub6 RF signal may be processed by a corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0055] The third RFIC (226) can convert the baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network (294) (e.g., 5G network). Upon reception, the 5G Above6 RF signal can be acquired from the second cellular network (294) (e.g., 5G network) through an antenna (e.g., antenna (248)) and preprocessed through the third RFFE (236). The third RFIC (226) can convert the preprocessed 5G Above6 RF signal into a baseband signal so that it can be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) can be formed as a part of the third RFIC (226).

[0056] The electronic device (101) may, according to one embodiment, include a fourth RFIC (228) separately from or at least as a part of the third RFIC (226). In this case, the fourth RFIC (228) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, referred to as an IF signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., antenna (248)) and converted into an IF signal by the third RFIC (226). The fourth RFIC (228) can convert the IF signal into a baseband signal so that the second communication processor (214) can process it.

[0057] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as a single chip or at least a portion of a single package. According to various embodiments, when the first RFIC (222) and the second RFIC (224) in FIG. 2A or FIG. 2B are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC may be connected to the first RFFE (232) and the second RFFE (234) to convert a baseband signal into a signal in a band supported by the first RFFE (232) and / or the second RFFE (234), and transmit the converted signal to one of the first RFFE (232) and the second RFFE (234). According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least a portion of a single chip or a single package. According to an example, at least one antenna module among the first antenna module (242) or the second antenna module (244) can be omitted or combined with another antenna module to process RF signals of a corresponding plurality of bands.

[0058] According to one embodiment, the third RFIC (226) and the antenna (248) may be disposed on the same substrate to form a third antenna module (246). For example, the wireless communication module (192) or the processor (120) may be disposed on the first substrate (e.g., the main PCB). In this case, the third RFIC (226) may be disposed on a portion (e.g., the bottom surface) of a second substrate (e.g., the sub PCB) separate from the first substrate, and the antenna (248) may be disposed on another portion (e.g., the top surface) to form the third antenna module (246). By disposing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line therebetween. This can reduce, for example, the loss (e.g., attenuation) of signals in a high-frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communications by the transmission line. This allows the electronic device (101) to improve the quality or speed of communication with a second cellular network (294) (e.g., a 5G network).

[0059] According to an example, the antenna (248) may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC (226) may include a plurality of phase shifters (238) corresponding to the plurality of antenna elements, for example, as part of the third RFFE (236). During transmission, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal to be transmitted to an external source (e.g., a base station of a 5G network) of the electronic device (101) via its corresponding antenna element. During reception, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal received from the external source via its corresponding antenna element to the same or substantially the same phase. This enables transmission or reception via beamforming between the electronic device (101) and the external source.

[0060] The second cellular network (294) (e.g., a 5G network) may operate independently (e.g., Stand-Alone (SA)) or in connection with (e.g., Non-Stand Alone (NSA)) the first cellular network (292) (e.g., a legacy network). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, the electronic device (101) may access an external network (e.g., the Internet) under the control of the core network (e.g., evolved packed core (EPC)) of the legacy network after accessing the access network of the 5G network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., New Radio (NR) protocol information) may be stored in the memory (230) and accessed by other components (e.g., the processor (120), the first communication processor (212), or the second communication processor (214)).

[0061] FIG. 3 is a block diagram of an electronic device including a power amplifier according to one embodiment. The embodiment of FIG. 3 will be described in more detail with reference to FIGS. 4A to 4C. FIGS. 4A to 4C are diagrams for explaining an operating mode according to one embodiment.

[0062] According to one embodiment, the electronic device (101) may include at least one of a power amplifier (380), a power control circuit (350), or a capacitor (361).

[0063] According to one embodiment, a communication processor (e.g., at least one of the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) can provide a baseband signal for transmission to an RFIC (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)). Alternatively, the communication processor (e.g., at least one of the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) can receive and process a baseband signal for reception from an RFIC (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)).

[0064] According to one embodiment, the processor (120) may execute a calling application. The processor (120) may perform a call based on the calling application. For example, the processor (120) may perform an outgoing call based on a call request from a user (e.g., selection of an icon for a calling request, or a voice command, but is not limited thereto), or may perform an incoming call based on a response request for an incoming call (e.g., selection of an icon for receiving, or a voice command, but is not limited thereto). For example, the processor (120) may perform a call based on an application that provides at least one calling function (e.g., a server-client based application), in addition to a calling application (e.g., an Internet protocol multimedia subsystem (IMS) based application), and those skilled in the art will understand that there is no limitation on the type of the application.

[0065] For example, the processor (120) can output voice for a call through a receiver. The receiver can be a device for outputting voice, and there is no limitation on the receiver. The receiver can be placed so as to be in contact with (or adjacent to) the user's ear, for example, when the user holds the electronic device (101), but there is no limitation on the placement location. For example, the processor (120) can set the receiver as a default output device for a call. For example, the processor (120) can also be set to output voice for a call through the receiver based on the fact that another accessory for voice output, for example, a wired voice output device (for example, but not limited to, a wired earphone) or a wirelessly connected voice output device (for example, but not limited to, a wireless earphone or a wireless speaker), is not operatively connected (for example, but not limited to, a physical connection or the establishment of a wireless communication channel (or connection)). For example, the processor (120) may be set to output voice for a call through the receiver based on not being set to speaker phone mode, but is not limited thereto.

[0066] According to one embodiment, an RFIC (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)) may generate an RF signal (e.g., Sig_in of FIG. 3) corresponding to a baseband signal for transmission and provide the RF signal to a power amplifier (380). The power amplifier (380) may be included in an RFFE (e.g., at least one of the first RFFE (232), the second RFFE (234), or the third RFFE (236)). The RFFE may be configured in the form of a power amplifier module (PAM), a front end module (FEM), a power amplifier module including duplexer (PAMiD), an LNA and PAM with an integrated duplexer or diplexer (LPAMID), or a PA with an integrated low noise amplifier and filter (LPAMIF), and there is no limitation on the form of implementation thereof. Those skilled in the art will understand that the RFFE may be implemented to further include filters and / or antenna switching modules (ASMs). Meanwhile, although FIG. 3 illustrates one power amplifier (380) as being included in the electronic device (101), this is for convenience of explanation, and those skilled in the art will understand that the electronic device (101) may be implemented to include multiple power amplifiers. Meanwhile, an RFFE including an RFIC (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)) and a power amplifier (380) may be referred to as an RF circuit.

[0067] According to one embodiment, the power control circuit (350) (e.g., at least one of a buck / boost converter, a buck converter, or a boost converter) can provide a supply voltage (Vcc) to the power amplifier (380) using the supplied power. For example, the power control circuit (350) can provide the supply voltage (Vcc) to the power amplifier (380) using power supplied from a power source (e.g., a battery (189) or an external power source). The power amplifier (380) can amplify an RF signal provided from an RFIC (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)) using the supply voltage (Vcc). The power control circuit (350) can be configured to operate, for example, in an average power tracking (APT) mode. Alternatively, the power control circuit (350) may operate in direct mode or ET mode. When operating in ET (envelope tracking) mode, the power control circuit (350) may be replaced with a linear amplifier. In one example, when operating in direct mode, the supply voltage (Vcc) (401) of the power amplifier (380) may be set to a specified value, as in FIG. 4a. In direct mode, the supply voltage (401) of the specified value may be provided to the power amplifier (380) regardless of the size of the transmission power per signal. In this case, the wasted power consumption may be relatively large. In another example, when operating in APT mode, the supply voltage (Vcc) (402) of the power amplifier (380) may be set (or changed) according to a specified time unit (e.g., slot (or subframe)), as in FIG. 4b.For example, in a subframe (or slot) in which the transmission power (e.g., transmission power, transmission power, transmission power) of an RF signal is set to 10 to 18 dBm, a supply voltage (Vcc) of 3 V may be supplied to the power amplifier (380), and in a subframe (or slot) in which the transmission power of the RF signal is set to 18 to 24 dBm, a supply voltage (Vcc) of 4 V may be supplied to the power amplifier (380). In another example, when operating in the ET mode, the supply voltage (Vcc) (403) of the power amplifier (380) may be set (or changed) in real time according to the magnitude of the transmission power of the RF signal, as shown in FIG. 4C. When operating in the ET mode, the power control circuit (350) may track the transmission power of the RF signal in real time and provide a supply voltage corresponding to an envelope of the transmission power to the power amplifier (380). The time interval of setting (or changing) the supply voltage (Vcc) in ET mode may be shorter than the time interval of setting (or changing) the supply voltage (Vcc) in APT mode. The communication processor (for example, at least one of the first communication processor (212), the second communication processor (214), or the integrated communication processor (260)) (or the modulator) may, for example, be based on an I / Q signal of a baseband signal (. ) can be used to determine the size of the supply voltage set in APT mode or ET mode. The electronic device (101) may include at least one of an envelope detector, an envelope shaper, or an amplifier, but is not limited thereto.

[0068] According to one embodiment, the power control circuit (350) may provide a supply voltage (Vcc) to the power amplifier (380) for transmitting an RF signal according to the APT mode. For example, the power control circuit (350) may include a switch. Depending on the determined magnitude of the supply voltage (Vcc), the on-duration and off-duration (or the ratio of the on-duration and off-duration) of the switch may be determined, but those skilled in the art will understand that there is no limitation on the method of controlling the magnitude of the supply voltage (Vcc) in the power control circuit (350). For example, when an RF signal of an ultra high band (UHB) or an operating band with a relatively wide bandwidth (e.g., B48 band, B42 band, N48 band, N41 band, N77 band, N78 band, or N79 band) is transmitted, the APT mode may be utilized, but there is no limitation. The power control circuit (350) can control the charge and / or discharge amount of the capacitor (361) to supply a determined supply voltage (Vcc).

[0069] Figure 5 is a cross-sectional view of a capacitor during charging and discharging according to one embodiment.

[0070] According to one embodiment, the cause of audible noise is caused by a phenomenon in which a capacitor (e.g., a capacitor (361) of FIG. 3) vibrates, and the vibration of the capacitor (e.g., a capacitor (361) of FIG. 3) may be caused by vibration of the internal plates stacked when charging and discharging occur due to the structure of the capacitor (e.g., a capacitor (361) of FIG. 3). For example, in order to reduce noise caused by vibration of a capacitor (e.g., a capacitor (361) of FIG. 3), the transmission of vibration must be blocked or the vibration must be prevented. For example, in order to reduce the amount of vibration, the amount of voltage being charged or the amount of voltage being discharged can be reduced. According to one embodiment, noise can be reduced by limiting the maximum swing width of charging or discharging through a capacitor bank (or capacitor filter) described below, thereby reducing capacitor vibration. For example, a capacitor (e.g., capacitor (361) of FIG. 3) may be charged during a transmission period and discharged during a non-transmission period. For example, during discharge, the capacitor (e.g., capacitor (361) of FIG. 3) may have a first shape (513a), and during charge, the capacitor (e.g., capacitor (361) of FIG. 3) may have a second shape (513b). The change in shape due to charging and discharging of the capacitor (e.g., capacitor (361) of FIG. 3) may cause a change in the shape of surrounding hardware, e.g., PCB, or solder. For example, when the capacitor (e.g., capacitor (361) of FIG. 3) has a first shape (513a), the PCB may have a first shape (511a), and the solder may have a first shape (512a). For example, if a capacitor (e.g., capacitor (361) of FIG. 3) has a second shape (513b), the PCB may have a second shape (511b) and the solder may have a second shape (512b).Such a change in shape may cause vibration, and if the frequency of the vibration is within the audible band (20 to 20,000 Hz), audible noise may be heard by the user. If a capacitor (e.g., capacitor (361) of FIG. 3) is placed close to a receiver of an electronic device (101), audible noise may be heard during a phone call, thereby degrading call quality. In particular, in a miniaturized electronic device (101), since the mounting area is small, the distance between the capacitor (e.g., capacitor (361) of FIG. 3) and the receiver may be designed very close, which may cause deterioration of call quality. In addition, if an operating frequency band requiring a relatively high transmission power and / or an operating frequency band supporting a relatively wide bandwidth is used, a relatively high supply voltage (Vcc) may be required. For example, a B38 frequency band with a bandwidth of 10 MHz may require a relatively low supply voltage (Vcc) of 2.9 V when the target transmit power is 23 dBm. However, a B48 frequency band with a bandwidth of 20 MHz, for example, may require a relatively high supply voltage (Vcc) of 4.4 V when the target transmit power is 24 dBm. For example, an N41 frequency band with a bandwidth of 50 MHz or more may require a relatively high supply voltage (Vcc) of 5.0 V when the target transmit power is 26 dBm. If a relatively high supply voltage (Vcc) is applied to a capacitor (e.g., capacitor (361) of FIG. 3) and then discharged, the voltage difference during charge-discharge may also be relatively large. A relatively large voltage difference during charge-discharge may cause relatively large audible noise.

[0071] According to one embodiment, the operation of the electronic device (101) may be understood as the operation of at least one of the components of the electronic device (101). For example, the operation of the electronic device (101) may be understood as the operation of at least one processor (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the integrated communication processor (260). For example, at least one processor (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the integrated communication processor (260)) may control at least one of the components of the electronic device (101). According to one embodiment, a storage medium (e.g., the memory (130)) that stores computer-readable instructions may be provided. Instructions stored in the storage medium (e.g., memory (130)) may, when executed by at least one processor (120; 212, 214; 260) of the electronic device (101), cause the electronic device (101) to perform at least one operation.

[0072] FIG. 6 is a flowchart of an operating method of a wireless power transmission device according to one embodiment.

[0073] The embodiment of FIG. 6 can be applied to embodiments of other drawings described later (e.g., FIGS. 7 to 13). The embodiment of FIG. 6 can be specifically described by embodiments of other drawings described later (e.g., FIGS. 7 to 13). For example, the embodiment of FIG. 6 can be applied to the embodiments of FIG. 7, FIG. 11, and FIG. 13. For example, in the description of FIG. 6, “supply voltage” can be the supply voltage of the embodiment of FIG. 7 (e.g., VCC), the supply voltage of the embodiment of FIG. 11 (e.g., VCC), or the supply voltage of the embodiment of FIG. 13 (e.g., VCC1, VCC2). For example, in the description of FIG. 6, the “reference voltage range (or reference range)” may be the reference range of the embodiment of FIG. 7 (e.g., the first reference range, the second reference range), the reference range of the embodiment of FIG. 11 (e.g., the first reference range, the second reference range, the third reference range, the fourth reference range), or the reference range of the embodiment of FIG. 13 (e.g., the first reference range, the second reference range). For example, in the description of FIG. 6, the “capacitor filter” may be the capacitor banks of FIG. 7 (e.g., 761, 762), the capacitor banks of FIG. 11 (e.g., 1161, 1162, 1163, 1164), or the capacitor banks of FIG. 13 (e.g., 1361, 1362). For example, in the description of FIG. 6, the “power amplifier” may be the power amplifier of FIG. 7 (e.g., 780), the power amplifier of FIG. 11 (e.g., 1180), or the power amplifier of FIG. 13 (e.g., 1381, 1382). For example, in the description of FIG. 6, the “power control circuit” may be the power control circuit of FIG. 7 (e.g., 750), the power control circuit of FIG. 11 (e.g., 1150), or the power control circuit of FIG. 13 (e.g., 1351, 1352).

[0074] In the embodiment of FIG. 6, the electronic device (101) may include a power control circuit (e.g., 750; 1150; 1351), a battery (189), a first capacitor bank (e.g., 761; 1161; 1361), a second capacitor bank (e.g., 762; 1162; 1362), a switch (e.g., 770; 1170; 1271, 1272, 1273, 1274; 1370), and a power amplifier (e.g., 780; 1180; 1381). The switches (e.g., 770; 1170; 1271,1272,1273,1274; 1370) may be configured to selectively connect the battery (189) to the first capacitor bank (e.g., 761; 1161; 1361). The switches (e.g., 770; 1170; 1271,1272,1273,1274; 1370) may be configured to selectively connect the power control circuit (750; 1150; 1351) to the first capacitor bank (761; 1161; 1361). The switches (e.g., 770; 1170; 1271, 1272, 1273, 1274; 1370) may be configured to selectively connect the power control circuit (750; 1150; 1351) to the second capacitor bank (762; 1162; 1362). The power amplifier (780; 1180; 1381) may be configured to receive a supply voltage based on the power provided from the power control circuit (750; 1150; 1351) and to amplify an RF signal based on the supply voltage.

[0075] According to one embodiment, the electronic device (101) may perform Tx transmission to the outside in operation 601. The Tx transmission may be an operation of transmitting an RF signal. For example, the electronic device (101) may perform Tx transmission by amplifying the RF signal based on the supply voltage provided to the power amplifiers (780, 1180, 1381, 1382). For example, the electronic device (101) may check the magnitude of the supply voltage (VCC) provided from the power control circuit (750; 1150; 1351). The electronic device (101) may check the voltage range that includes the checked supply voltage. The electronic device (101) may check a reference voltage range (or reference range (e.g., current reference range)) based on the voltage range that includes the supply voltage. A specific reference range may be set corresponding to a specific capacitor bank. The electronic device (101) can perform Tx transmission while the power control circuit (750; 1150; 1351) is connected to the capacitor bank corresponding to the verified reference range.

[0076] According to one embodiment, in operation 603, the electronic device (101) may check whether the supply voltage (VCC) provided from the power control circuit (750; 1150; 1351) is included in a reference range (e.g., a new reference range) that causes a change in the capacitor filter. For example, the electronic device (101) may check the magnitude of the supply voltage provided from the power control circuit (750; 1150; 1351) and check whether the checked supply voltage is included in a reference range that causes a change in the capacitor filter. The “reference range that causes a change in the capacitor filter” may be a new reference range that is different from the current (or existing) reference range. The current (or existing) reference range may be a reference range corresponding to a capacitor bank currently connected to the power control circuit (750; 1150; 1351). The new reference range may be a reference range corresponding to a capacitor bank different from the capacitor bank currently connected to the power control circuit (750; 1150; 1351). For example, in operation 603, if the supply voltage is included in the reference range (or reference voltage range), it may mean that the supply voltage is included in the new reference range. For example, in operation 603, if the supply voltage is not included in the reference range (or reference voltage range), it may mean that the supply voltage is not included in the new reference range. For example, in operation 603, if the supply voltage is not included in the reference range (or reference voltage range), it may mean that the supply voltage is included in the existing reference range. In one embodiment, the operation of determining whether the supply voltage (VCC) is included in the reference range may include the operation of determining whether the supply voltage (VCC) is equal to or greater than a first reference voltage. In one embodiment, the operation of determining whether the supply voltage (VCC) is within a reference range may include determining whether the supply voltage (VCC) is less than (or below) a second reference voltage.In one embodiment, the operation of determining whether the supply voltage (VCC) is within a reference range may include determining whether the supply voltage (VCC) is greater than a third reference voltage and less than or equal to a fourth reference voltage. In one embodiment, the operation of determining whether the supply voltage (VCC) is within a reference range may include determining whether a change in the supply voltage (VCC) is greater than (or equal to) a first reference amount. In one embodiment, the operation of determining whether the supply voltage (VCC) is within a reference range may include determining whether a change in the supply voltage (VCC) is less than (or equal to) a second reference amount. Specific embodiments of the operation of determining whether the supply voltage (VCC) is within a reference range will be described with reference to the drawings described below.

[0077] According to one embodiment, the electronic device (101) may maintain the existing capacitor filter at operation 605 based on the supply voltage (VCC) not being within the new reference voltage range (or reference range). "Maintaining the existing capacitor filter" may mean maintaining the connection with the capacitor bank currently connected to the power control circuit (750; 1150; 1351).

[0078] According to one embodiment, the electronic device (101) may change the capacitor filter at operation 607 based on whether the supply voltage (VCC) falls within a new reference voltage range (or reference range). "Changing the capacitor filter" may mean disconnecting the capacitor bank currently connected to the power control circuit (750; 1150; 1351) and connecting the power control circuit (750; 1150; 1351) to the new capacitor bank.

[0079] According to one embodiment, the electronic device (101) may change the Tx transmission power (e.g., output power) after operation 605 or operation 607. For example, the electronic device (101) may change the Tx transmission power based on the operating frequency band. As the Tx transmission power is changed, operation 603 may be performed. According to one embodiment, the supply voltage (VCC) may be set according to the Tx transmission power (e.g., output power). For example, the supply voltage (VCC) may be matched according to the output power. According to one embodiment, the supply voltage (VCC) may vary according to the band / modulation. According to one embodiment, the electronic device (101) may store the setting value of the corresponding supply voltage (VCC) according to the output power, and select a capacitor filter corresponding to the output power, thereby minimizing the amount of charge and discharge that causes capacitor shaking, thereby reducing or eliminating audio noise.

[0080] FIG. 7 is a connection diagram of components of an electronic device according to one embodiment. FIG. 8 is a circuit diagram of an electronic device according to one embodiment. FIG. 9 is a graph of voltages applied to a capacitor bank connected to a power amplifier according to one embodiment.

[0081] The embodiment of FIG. 6 will be described in detail with reference to the embodiments of FIGS. 7, 8, and 9. FIG. 8 is an exemplary circuit diagram corresponding to FIG. 7, but the circuit diagram corresponding to FIG. 7 is not limited to the embodiment of FIG. 8.

[0082] Referring to FIG. 7, the electronic device (101) may include a power control circuit (750), a battery (189), a switch (770), a first capacitor bank (761), a second capacitor bank (762), and a power amplifier (780). The power control circuit (750) may be the power control circuit (350) of FIG. 3. The power amplifier (780) may be the power amplifier (380) of FIG. 3. The power amplifier (780) may amplify an input signal (Sig_in) based on the supply power (VCC) provided from the power control circuit (750) to output an output signal (Sig_out). Referring to FIG. 8, a resistor (891) and a capacitor (892) may be connected to an input terminal of the power amplifier (780), and a resistor (894) and a capacitor (893) may be connected to an output terminal of the power amplifier (780). The switch (770) may include a plurality of nodes. Components of the electronic device (101) may be electrically connected to the plurality of nodes of the switch (770). Depending on the operation of the switch (770), the plurality of nodes of the switch (770) may be electrically connected to each other, thereby electrically connecting the components of the electronic device (101) to each other. Hereinafter, electrically connecting the components of the electronic device (101) may mean electrically connecting nodes corresponding to the components of the electronic device (101) among the plurality of nodes of the switch (770) to each other, depending on the operation of the switch (770).

[0083] Referring to FIG. 8, the first capacitor bank (761) may include a plurality of capacitors (e.g., 861a, 861b, 861c). Although FIG. 8 illustrates that the first capacitor bank (761) includes three capacitors (e.g., 861a, 861b, 861c), this is merely an example, and there is no limitation on the number of capacitors included in the first capacitor bank (761). The second capacitor bank (762) may include a plurality of capacitors (e.g., 862a, 862b, 862c). Although FIG. 8 illustrates that the second capacitor bank (762) includes three capacitors (e.g., 862a, 862b, 862c), this is merely an example, and there is no limitation on the number of capacitors included in the second capacitor bank (762).

[0084] Referring to FIG. 7, the switch (770) may be configured to selectively connect the battery (189) to the first capacitor bank (761). For example, referring to FIG. 8, the switch (770) may connect the battery (189) to the first capacitor bank (761) (e.g., by connecting 1 and 3 in 770 of FIG. 8) or may not connect the battery (189) to the first capacitor bank (761) (e.g., by connecting 1 and 2 in 770 of FIG. 8). Referring to FIG. 7, the switch (770) may be configured to selectively connect the power control circuit (750) to the first capacitor bank (761). The switch (770) may be configured to selectively connect the power control circuit (750) to the second capacitor bank (762). For example, the switch (770) may be configured to selectively connect the power control circuit (750) to the first capacitor bank (761) or the second capacitor bank (762). For example, referring to FIG. 8, the switch (770) may connect the power control circuit (750) to the first capacitor bank (761) (e.g., by connecting 4 and 6 in 770 of FIG. 8) or connect the power control circuit (750) to the second capacitor bank (762) (e.g., by connecting 4 and 5 in 770 of FIG. 8).

[0085] Referring to the embodiments of FIGS. 7 and 8, the Tx transmission of operation 601 of FIG. 6 will be described as follows. The electronic device (101) can control the switch (770) so that the battery (189) and the first capacitor bank (761) are connected. The electronic device (101) can control the switch (770) so that the power control circuit (750) and the second capacitor bank (762) are connected. The electronic device (101) can amplify a signal through the power amplifier (780) using the supply voltage (VCC) provided from the power control circuit (750) while the battery (189) and the first capacitor bank (761) are connected and the power control circuit (750) and the second capacitor bank (762) are connected. At this time, the supply voltage (VCC) provided from the power control circuit (750) may be included in a reference range (e.g., a first reference range) corresponding to the second capacitor bank (762) connected to the power control circuit (750). For example, the reference range (e.g., a first reference range) corresponding to the second capacitor bank (762) may be a range that includes voltages lower than the reference voltage. In the embodiments of FIGS. 7 and 8, the “reference voltage” may be determined based on a set value of the supply voltage. For example, when the set value of the supply voltage (VCC) provided from the power control circuit (750) is set from the first voltage (e.g., 0.6 [V]) to the second voltage (e.g., 4.5 [V]), the reference voltage may be determined as half of the value obtained by subtracting the first voltage from the second voltage (e.g., 2.55 [V]), but those skilled in the art will understand that there is no limitation on the method by which the reference voltage is determined. For example, in the embodiments of FIGS. 7 and 8, when the reference voltage is determined to be 2.55 [V], the reference range (e.g., the first reference range) corresponding to the second capacitor bank (762) may be a range that includes voltages less than the reference voltage of 2.55 [V], but those skilled in the art will understand that this is an exemplary value.According to one embodiment, in the case of an embodiment in which the amount of change in the supply voltage (VCC) is compared with a reference amount, the reference range (e.g., the first reference range) corresponding to the second capacitor bank (762) in the embodiments of FIGS. 7 and 8 may be a range in which the amount of change in the supply voltage (VCC) is less than the reference amount. For example, when the set value of the supply voltage (VCC) provided from the power control circuit (750) is set from the first voltage (e.g., 0.6 [V]) to the second voltage (e.g., 4.5 [V]), the reference amount may be determined as a value (e.g., 1.95 [V]) obtained by subtracting the first voltage (e.g., 0.6 [V]) from half of the value obtained by subtracting the first voltage from the second voltage (e.g., 2.55 [V]), but those skilled in the art will understand that there is no limitation on the method by which the reference amount is determined. For example, in the embodiments of FIGS. 7 and 8, when the reference amount is determined to be 1.95 [V], the reference range (e.g., the first reference range) corresponding to the second capacitor bank (762) may be a range in which the amount of change in the supply voltage (VCC) is less than the reference amount of 1.95 [V], but those skilled in the art will understand that this is an exemplary value.

[0086] Referring to the embodiments of FIGS. 7 and 8, operation 603 of FIG. 6 will be described as follows. While the electronic device (101) performs Tx transmission, the supply voltage (VCC) provided from the power control circuit (750) may vary. For example, the electronic device (101) may check the magnitude of the supply voltage (VCC) provided from the power control circuit (750). The electronic device (101) may check whether the checked supply voltage is included in a new reference range (e.g., a second reference range). The new reference range (e.g., the second reference range) may be a voltage range corresponding to the first capacitor bank (761). For example, the reference range (e.g., the second reference range) corresponding to the first capacitor bank (761) may be a range including voltages that are equal to or greater than the reference voltage. For example, if the set value of the supply voltage (VCC) provided from the power control circuit (750) is set from the first voltage (e.g., 0.6 [V]) to the second voltage (e.g., 4.5 [V]), the reference voltage may be determined as half of the value obtained by subtracting the first voltage from the second voltage (e.g., 2.55 [V]), but those skilled in the art will understand that there is no limitation on the method by which the reference voltage is determined. For example, if the reference voltage is determined as 2.55 [V] in the embodiments of FIGS. 7 and 8, the reference range (e.g., the second reference range) corresponding to the first capacitor bank (761) may be a range that includes voltages that are equal to or higher than the reference voltage of 2.55 [V], but those skilled in the art will understand that this is an exemplary value. According to one embodiment, in the case of an embodiment in which the amount of change in the supply voltage (VCC) is compared with a reference amount, in the embodiments of FIGS. 7 and 8, the electronic device (101) can check the amount of change in the supply voltage (VCC) provided from the power control circuit (750). The electronic device (101) can check whether the checked amount of change exceeds the reference amount.For example, the electronic device (101) can determine whether to change or maintain the capacitor filter by checking the amount of change in the supply voltage (VCC) and comparing the checked amount of change with a reference amount. For example, the electronic device (101) can maintain the existing capacitor filter based on the amount of change in the supply voltage (VCC) being less than the reference amount. For example, the electronic device (101) can change the capacitor filter based on the amount of change in the supply voltage (VCC) being greater than the reference amount.

[0087] Referring to the embodiments of FIGS. 7 and 8, operation 605 of FIG. 6 will be described as follows. The electronic device (101) may maintain the existing capacitor filter based on the identified supply voltage not being included in a new reference range (e.g., a second reference range corresponding to the first capacitor bank (761)) (i.e., based on the identified supply voltage being included in an existing reference range (e.g., a first reference range corresponding to the second capacitor bank (762)). Maintaining the existing capacitor filter based on the first reference range may mean maintaining a state in which the power control circuit (750) and the second capacitor bank (762) are connected, and the battery (189) and the first capacitor bank (761) are connected. In one embodiment, for an embodiment in which the amount of change in the supply voltage (VCC) is compared with a reference amount, in the embodiments of FIGS. 7 and 8, the electronic device (101) may maintain the existing capacitor filter (e.g., the second capacitor bank (762)) based on the amount of change in the supply voltage (VCC) being less than the reference amount.

[0088] Referring to the embodiments of FIGS. 7 and 8, operation 607 of FIG. 6 will be described as follows. The electronic device (101) may change the capacitor filter based on whether the identified supply voltage falls within a new reference range (e.g., a second reference range corresponding to the first capacitor bank (761)). Changing the capacitor filter based on the second reference range may include disconnecting the battery (189) and the first capacitor bank (761), disconnecting the power control circuit (750) and the second capacitor bank (762), and connecting the power control circuit (750) and the first capacitor bank (761). According to one embodiment, in the embodiment of comparing the amount of change in the supply voltage (VCC) with a reference amount, in the embodiments of FIGS. 7 and 8, the electronic device (101) may change the capacitor filter (e.g., change to the first capacitor bank (761)) based on the amount of change in the supply voltage (VCC) being greater than or equal to the reference amount.

[0089] Thereafter, the electronic device (101) may perform operation 603 again and change the capacitor filter based on whether the supply voltage falls within a new reference range (e.g., the first reference range corresponding to the second capacitor bank (762)), or maintain the capacitor filter based on whether the supply voltage falls within an existing reference range (e.g., the second reference range corresponding to the first capacitor bank (761)). For example, maintaining the capacitor filter based on the second reference range corresponding to the first capacitor bank (761) may mean maintaining the power control circuit (750) and the first capacitor bank (761) in a connected state. For example, changing the capacitor filter based on the first reference range corresponding to the second capacitor bank (762) may include disconnecting the power control circuit (750) and the first capacitor bank (761), connecting the power control circuit (750) and the second capacitor bank (762), and connecting the battery (189) and the first capacitor bank (761). In one embodiment, in the case of an embodiment in which the amount of change in the supply voltage (VCC) is compared with a reference amount, in the embodiments of FIGS. 7 and 8, the electronic device (101) may determine whether to change (e.g., change to the second capacitor bank (762)) or maintain (e.g., maintain the first capacitor bank (761)) the capacitor filter by checking the amount of change in the supply voltage (VCC) and comparing the checked amount of change with the reference amount.

[0090] FIG. 9 is a graph of a supply voltage (VCC), a first voltage (VCB1) corresponding to a first capacitor bank (761), and a second voltage (VCB2) corresponding to a second capacitor bank (762), according to the embodiment of FIGS. 7 and 8.

[0091] Referring to FIG. 9, it can be confirmed that the swing width (e.g., the difference between the maximum voltage and the minimum voltage) of the first voltage (VCB1) corresponding to the first capacitor bank (761) and the swing width of the second voltage (VCB2) corresponding to the second capacitor bank (762) are smaller than the swing width of the supply voltage (VCC). For example, in FIG. 9, (a) may represent the supply voltage (VCC), (b) may represent the first voltage (VCB1) corresponding to the first capacitor bank (761), and (c) may represent the second voltage (VCB2) corresponding to the second capacitor bank (762). In Fig. 9, the supply voltage (VCC) swings by 3.6 [V] from 0.6 [V] to 4.2 [V], but the first voltage (VCB1) can swing by 0.7 [V] from 3.5 [V] to 4.2 [V], and the second voltage (VCB2) can swing by 1.6 [V] from 0 [V] to 1.6 [V]. Consequently, since the swing width of the first voltage (VCB1) and the swing width of the second voltage (VCB2) are smaller than the swing width of the supply voltage (VCC), noise due to charging and discharging of the capacitor can be reduced.

[0092] FIG. 10 is a diagram illustrating replacement of a capacitor bank according to one embodiment.

[0093] Referring to FIG. 10, the replacement of the capacitor bank of the embodiments of FIGS. 7 and 8 will be described. The following description can be similarly applied to the replacement of the capacitor bank of the embodiment of FIG. 11 or the replacement of the capacitor bank of the embodiment of FIG. 13, and the description of FIGS. 11 and 13 will be omitted. Although the expression "replacement" is used herein, this is for the convenience of explanation, and the capacitor bank may be implemented from the beginning, as in the embodiment of FIG. 10, when manufacturing the electronic device (101).

[0094] Referring to FIG. 10, a replacement of a capacitor bank will be described, and referring to FIG. 7, how a capacitor bank can be replaced will be described. It will be understood by those skilled in the art that the number of capacitors (e.g., 1062a, 1062b, 1062c, 1069a, 1069b) included in a capacitor bank (e.g., 1062, 1069) in FIG. 10 is exemplary. In one embodiment, a capacitor (or capacitor bank) having a lower operating voltage can be replaced with a capacitor (or capacitor bank) having a lower capacitor value. For example, in FIG. 10, a capacitor bank (1062) including a first capacitor (1062a), a second capacitor (1062b), and a third capacitor (1062c) may be replaced with a capacitor bank (1069) including a fourth capacitor (1069a) and a fifth capacitor (1069b). At this time, the capacitance of the capacitor bank (1069) including the fourth capacitor (1069a) and the fifth capacitor (1069b) may be smaller than the capacitance of the capacitor bank (1062) including the first capacitor (1062a), the second capacitor (1062b), and the third capacitor (1062c). For example, the capacitance of the first capacitor (1062a) may be 100 [pF], the capacitance of the second capacitor (1062b) may be 2.2 [uF], the capacitance of the third capacitor (1062c) may be 1 [uF], the capacitance of the fourth capacitor (1069a) may be 100 [pF], and the capacitance of the fifth capacitor (1069b) may be 1 [nF].

[0095] For example, referring to FIGS. 7 and 9, the minimum value of the first voltage (VCB1) corresponding to the first capacitor bank (761) may be greater than or equal to the maximum value of the second voltage (VCB2) corresponding to the second capacitor bank (762). That is, the operating voltage of the first capacitor bank (761) and the operating voltage of the second capacitor bank (762) may be different. As a result, the second capacitor bank (762) may be implemented as a capacitor bank having a capacitance smaller than the capacitance of the first capacitor bank (761). In summary, the first capacitor bank (761) and the second capacitor bank (762) may be configured identically and thus may have the same capacitance, but the second capacitor bank (762) may be implemented as a capacitor bank having a capacitance smaller than that of the first capacitor bank (761), so that the first capacitor bank (761) and the second capacitor bank (762) may be configured differently. That is, the capacitance of the second capacitor bank (762) may be smaller than the capacitance of the first capacitor bank (761). Similarly, in the embodiment of FIG. 11 or the embodiment of FIG. 13 described below, capacitor banks having different operating voltages among the plurality of capacitor banks may be implemented to have different capacitances.

The fourth capacitor bank (1164) may include a plurality of capacitors (e.g., 1264a, 1264b, 1264c). Although FIG. 12 illustrates that the fourth capacitor bank (1164) includes three capacitors (e.g., 1264a, 1264b, 1264c), this is merely an example, and there is no limitation on the number of capacitors included in the fourth capacitor bank (1164). As described above in FIG. 10, the first capacitor bank (1161), the second capacitor bank (1162), the third capacitor bank (1163), and the fourth capacitor bank (1164) may be implemented to have the same capacitance, or may be implemented to have different capacitances depending on the operating voltage.

[0100] Referring to FIG. 12, the switch (1170) may include a first switch (1271), a second switch (1272), a third switch (1273), and a fourth switch (1274), but the configuration of the switch (1170) is not limited to the embodiment of FIG. 12. The plurality of nodes of the switch (1170) may include a plurality of nodes of the first switch (1271), a plurality of nodes of the second switch (1272), a plurality of nodes of the third switch (1273), and a plurality of nodes of the fourth switch (1274).

If the switch (1170) (e.g., the third switch (1273) and the fourth switch (1274)) is connected differently, the third capacitor bank (1163) may not be connected to the power control circuit (1150).

[0108] Referring to FIG. 11, the switch (1170) may be configured to selectively connect the fourth capacitor bank (1164) to the power control circuit (1150). For example, referring to FIG. 12, the switch (1170) (e.g., the third switch (1273) and the fourth switch (1274)) may connect the fourth capacitor bank (1164) to the power control circuit (1150) (e.g., by connecting 4 and 5 in 1273 and connecting 1 and 3 in 1274 of FIG. 12). If the switch (1170) (e.g., the third switch (1273) and the fourth switch (1274)) is connected differently, the fourth capacitor bank (1164) may not be connected to the power control circuit (1150).

[0109] Referring to the embodiments of FIGS. 11 and 12, the Tx transmission of operation 601 of FIG. 6 will be described as follows. For example, the electronic device (101) can control the switch (770) so that the battery (189) and the first capacitor bank (1161) are connected. The electronic device (101) can control the switch (770) so that the first resistor divider (1141) and the second capacitor bank (1162) are connected. The electronic device (101) can control the switch (770) so that the second resistor divider (1142) and the third capacitor bank (1163) are connected. The electronic device (101) can control the switch (770) so that the power control circuit (1150) and the fourth capacitor bank (1164) are connected. The electronic device (101) can amplify a signal through a power amplifier (1180) using a supply voltage (VCC) provided from the power control circuit (1150) in a state where a battery (189) and a first capacitor bank (1161) are connected, a first resistor divider (1141) and a second capacitor bank (1162) are connected, a second resistor divider (1142) and a third capacitor bank (1163) are connected, and a power control circuit (1150) and a fourth capacitor bank (1164) are connected. Compared to the embodiment of FIG. 7, according to the embodiments of FIGS. 11 and 12, the capacitor banks (e.g., 1161, 1162, 1163, 1164) are expandable. When the capacitor banks (e.g., 1161, 1162, 1163, 1164) are expanded, the change voltage (e.g., the reference amount of the change in the supply voltage (VCC)) and the reference voltage that serve as a basis for changing the capacitor filter can be changed according to the expanded number of capacitor filters. According to one embodiment, the constant voltage value (e.g., V0, V1, V2, V3 of FIG. 12) for each capacitor bank can be adjusted to reduce the voltage swing width of the capacitor filter. According to one embodiment, noise can be reduced by reducing the amount of change in the voltage of the capacitor filter.For example, referring to FIGS. 11 and 12, a reference range (e.g., a first reference range) corresponding to a first capacitor bank (1161) may be a range including voltages that are higher than or equal to a first reference voltage (V1). The first reference voltage may be a voltage of a second resistor (1241b) of a first resistor divider (1141). A reference range (e.g., a second reference range) corresponding to a second capacitor bank (1162) may be a range including voltages that are lower than the first reference voltage (V1) and higher than or equal to a second reference voltage (V2). The second reference voltage may be a voltage of a fourth resistor (1242b) of a second resistor divider (1142). The reference range (e.g., the third reference range) corresponding to the third capacitor bank (1163) may be a range that includes voltages that are less than the second reference voltage (V2) and greater than or equal to the third reference voltage (V3). The third reference voltage may be the voltage of the sixth resistor (1243b) of the third resistor divider (1143). The reference range (e.g., the fourth reference range) corresponding to the fourth capacitor bank (1164) may be a range that includes voltages that are less than the third reference voltage (V3). Therefore, in operation 601, the supply voltage (VCC) provided from the power control circuit (1150) may be included in the reference range (e.g., the fourth reference range) corresponding to the fourth capacitor bank (1164) connected to the power control circuit (1150).Hereinafter, an embodiment in which the supply voltage (VCC) is included in a reference range (e.g., the fourth reference range) corresponding to the fourth capacitor bank (1164) is described as an example, and with reference to this description, it is also possible to understand an embodiment in which the supply voltage (VCC) is not included in a reference range (e.g., the fourth reference range) corresponding to the fourth capacitor bank (1164), but in a reference range (e.g., the first reference range) corresponding to the first capacitor bank (1161), a reference range (e.g., the second reference range) corresponding to the second capacitor bank (1162), or a reference range (e.g., the third reference range) corresponding to the third capacitor bank (1163).

[0110] Referring to the embodiments of FIGS. 11 and 12, operation 603 of FIG. 6 will be described as follows. While the electronic device (101) performs Tx transmission, the supply voltage (VCC) provided from the power control circuit (750) may vary. The electronic device (101) can check the magnitude of the supply voltage (VCC) provided from the power control circuit (750). The electronic device (101) can check whether the checked supply voltage is included in a new reference range (e.g., a first reference range, a second reference range, or a third reference range).

[0111] Referring to the embodiments of FIGS. 11 and 12, operation 605 of FIG. 6 is described as follows. The electronic device (101) may maintain the existing capacitor filter based on the identified supply voltage not being included in a new reference range (e.g., a first reference range, a second reference range, or a third reference range) (i.e., based on the identified supply voltage being included in an existing reference range (e.g., a fourth reference range corresponding to a fourth capacitor bank (1164)). Maintaining the existing capacitor filter based on the fourth reference range may be to maintain the existing state of connecting the power control circuit (1150) and the fourth capacitor bank (1164), connecting the battery (189) and the first capacitor bank (1161), connecting the first resistor divider (1141) and the second capacitor bank (1162), and connecting the second resistor divider (1142) and the third capacitor bank (1163).

[0112] Referring to the embodiments of FIGS. 11 and 12, operation 607 of FIG. 6 will be described as follows. The electronic device (101) can change the capacitor filter based on whether the identified supply voltage falls within a new reference range (e.g., a first reference range, a second reference range, or a third reference range). For example, changing the capacitor filter based on the first reference range may include disconnecting the battery (189) and the first capacitor bank (1161), disconnecting the power control circuit (1150) and the fourth capacitor bank (1164), connecting the power control circuit (1150) and the first capacitor bank (1161), connecting the third resistor divider (1143) and the fourth capacitor bank (1164), maintaining the connection between the first resistor divider (1141) and the second capacitor bank (1162), and maintaining the connection between the second resistor divider (1142) and the third capacitor bank (1163). For example, changing the capacitor filter based on the second reference range may include disconnecting the first resistor divider (1141) and the second capacitor bank (1162), disconnecting the power control circuit (1150) and the fourth capacitor bank (1164), connecting the power control circuit (1150) and the second capacitor bank (1162), connecting the third resistor divider (1143) and the fourth capacitor bank (1164), maintaining the connection of the battery (189) and the first capacitor bank (1161), and maintaining the connection of the second resistor divider (1142) and the third capacitor bank (1163).For example, changing the capacitor filter based on the third reference range may include disconnecting the second resistor divider (1142) and the third capacitor bank (1163), disconnecting the power control circuit (1150) and the fourth capacitor bank (1164), connecting the power control circuit (1150) and the third capacitor bank (1163), connecting the third resistor divider (1143) and the fourth capacitor bank (1164), maintaining the connection between the battery (189) and the first capacitor bank (1161), and maintaining the connection between the first resistor divider (1141) and the second capacitor bank (1162).

[0113] Thereafter, the electronic device (101) may perform operation 603 again and change the capacitor filter based on whether the supply voltage falls within a new reference range (e.g., a fourth reference range corresponding to the fourth capacitor bank (1164)), or maintain the capacitor filter based on whether the supply voltage falls within an existing reference range (e.g., a first reference range, a second reference range, or a third reference range). For example, changing the capacitor filter based on the fourth reference range corresponding to the fourth capacitor bank (1164) may include disconnecting a capacitor bank (e.g., 1161, 1162, or 1163) connected to the power control circuit (750), connecting the power control circuit (750) and the fourth capacitor bank (1164), connecting the battery (189) and the first capacitor bank (1161), connecting the first resistor divider (1141) and the second capacitor bank (1162), and connecting the second resistor divider (1142) and the third capacitor bank (1163).

The embodiment of FIG. 13 can be exemplarily described for a case in which a first output signal (Sig1_out) is output by amplifying a first input signal (Sig1_in) based on a first supply power (VCC1). At this time, the second supply power (VCC2) may or may not be supplied.

[0117] According to one embodiment, the first capacitor bank (1361) may include a plurality of capacitors. There is no limitation on the number of capacitors included in the first capacitor bank (1361). The second capacitor bank (1362) may include a plurality of capacitors. There is no limitation on the number of capacitors included in the second capacitor bank (1362).

[0118] Referring to FIG. 13, the switch (1370) may be configured to selectively connect the battery (189) to the first capacitor bank (1361). The switch (1370) may be configured to selectively connect the battery (189) to the second capacitor bank (1362). For example, the switch (1370) may be configured to selectively connect the battery (189) to the first capacitor bank (1361), the second capacitor bank (1362), or an empty node (1390). The switch (1370) may be configured to selectively connect the first power control circuit (1351) to the first capacitor bank (1361). The switch (1370) may be configured to selectively connect the first power control circuit (1351) to the second capacitor bank (1362). For example, the switch (1370) may be configured to selectively connect the first power control circuit (1351) to the first capacitor bank (1361) or the second capacitor bank (1362). The switch (1370) may be configured to selectively connect the second power control circuit (1352) to the second capacitor bank (1362). The switch (1370) may be configured to selectively connect the second power control circuit (1352) to the first capacitor bank (1361). For example, the switch (1370) may be configured to selectively connect the first power control circuit (1351) to the first capacitor bank (1361) or the second capacitor bank (1362).

[0119] Referring to the embodiment of FIG. 13, the Tx transmission of operation 601 of FIG. 6 will be described as follows. The electronic device (101) can control the switch (1370) so that the battery (189) and the second capacitor bank (1362) are connected. The electronic device (101) can control the switch (1370) so that the first power control circuit (1351) and the first capacitor bank (1361) are connected. The electronic device (101) can amplify a signal through the first power amplifier (1381) using the first supply voltage (VCC1) provided from the first power control circuit (1351) in a state where the battery (189) and the second capacitor bank (1362) are connected, and the first power control circuit (1351) and the first capacitor bank (1361) are connected. At this time, the first supply voltage (VCC1) provided from the first power control circuit (1351) may be included in a reference range (e.g., a first reference range) corresponding to the first capacitor bank (1361) connected to the first power control circuit (1351). For example, the reference range (e.g., a first reference range) corresponding to the first capacitor bank (1361) may be a range including voltages lower than the reference voltage. In the embodiment of Fig. 13, the “reference voltage” may be determined based on the first set value of the first supply voltage (VCC1). That is, the first power control circuit (1351) may adjust the first supply voltage (VCC1). For example, when the first set value of the first supply voltage (VCC1) provided from the first power control circuit (1351) is set from the first voltage (e.g., 0.6 [V]) to the second voltage (e.g., 4.5 [V]), the reference voltage may be determined as half of the value obtained by subtracting the first voltage from the second voltage (e.g., 2.55 [V]), but those skilled in the art will understand that there is no limitation on the method by which the reference voltage is determined. For example, in the embodiment of FIG. 13, the reference voltage is 2.When determined as 55 [V], the reference range (e.g., the first reference range) corresponding to the first capacitor bank (1361) may be a range including voltages less than the reference voltage of 2.55 [V], but it can be understood by those skilled in the art that this is an exemplary value. According to one embodiment, in the case of an embodiment in which the amount of change in the supply voltage (VCC) is compared with the reference amount, in the embodiment of FIG. 13, the reference range (e.g., the first reference range) corresponding to the first capacitor bank (1361) may be a range in which the amount of change in the supply voltage (VCC) is less than the reference amount. For example, if the first set value of the first supply voltage (VCC1) provided from the first power control circuit (1351) is set from the first voltage (e.g., 0.6 [V]) to the second voltage (e.g., 4.5 [V]), the reference amount may be determined as a value (e.g., 1.95 [V]) obtained by subtracting the first voltage (e.g., 0.6 [V]) from half of the value obtained by subtracting the first voltage from the second voltage (e.g., 2.55 [V]), but those skilled in the art will understand that there is no limitation on the method by which the reference amount is determined. For example, in the embodiment of FIG. 13, if the reference amount is determined to be 1.95 [V], the reference range (e.g., the first reference range) corresponding to the first capacitor bank (1361) may be a range in which the amount of change in the supply voltage (VCC) is less than the reference amount of 1.95 [V], but those skilled in the art will understand that this is an exemplary value.

[0120] Referring to the embodiment of FIG. 13, the operation 603 of FIG. 6 will be described as follows. While the electronic device (101) performs Tx transmission, the first supply voltage (VCC1) provided from the first power control circuit (1351) may vary. The electronic device (101) may check the magnitude of the first supply voltage (VCC1) provided from the first power control circuit (1351). The electronic device (101) may check whether the checked first supply voltage is included in a new reference range (e.g., a second reference range). The new reference range (e.g., the second reference range) may be a voltage range corresponding to the second capacitor bank (1362). For example, the reference range (e.g., the second reference range) corresponding to the second capacitor bank (1362) may be a range including voltages that are equal to or greater than the reference voltage. For example, if the first set value of the first supply voltage (VCC1) provided from the first power control circuit (1351) is set from the first voltage (e.g., 0.6 [V]) to the second voltage (e.g., 4.5 [V]), the reference voltage may be determined as half of the value obtained by subtracting the first voltage from the second voltage (e.g., 2.55 [V]), but those skilled in the art will understand that there is no limitation on the method by which the reference voltage is determined. For example, in the embodiment of FIG. 13, if the reference voltage is determined as 2.55 [V], the reference range corresponding to the second capacitor bank (1362) (e.g., the second reference range) may be a range that includes voltages that are equal to or greater than the reference voltage of 2.55 [V], but those skilled in the art will understand that this is an exemplary value.

[0121] Referring to the embodiment of FIG. 13, operation 605 of FIG. 6 will be described as follows. The electronic device (101) may maintain the existing capacitor filter based on the fact that the identified first supply voltage is not included in a new reference range (e.g., a second reference range corresponding to the second capacitor bank (1362)) (i.e., based on the fact that the identified supply voltage is included in an existing reference range (e.g., a first reference range corresponding to the first capacitor bank (1361)). Maintaining the existing capacitor filter based on the first reference range may mean maintaining a state in which the first power control circuit (1351) and the first capacitor bank (1361) are connected, and the battery (189) and the second capacitor bank (1362) are connected.

[0122] Referring to the embodiment of FIG. 13, the operation 607 of FIG. 6 will be described as follows. The electronic device (101) can change the capacitor filter based on whether the identified first supply voltage falls within a new reference range (e.g., a second reference range corresponding to the second capacitor bank (1362)). Changing the capacitor filter based on the second reference range may include disconnecting the battery (189) and the second capacitor bank (1362), disconnecting the first power control circuit (1351) and the first capacitor bank (1361), and connecting the first power control circuit (1351) and the second capacitor bank (1362).

[0123] Thereafter, the electronic device (101) may perform operation 603 again and change the capacitor filter based on whether the first supply voltage falls within a new reference range (e.g., the first reference range corresponding to the first capacitor bank (1361)), or maintain the capacitor filter based on whether the first supply voltage falls within an existing reference range (e.g., the second reference range corresponding to the second capacitor bank (1362)). For example, maintaining the capacitor filter based on the second reference range corresponding to the second capacitor bank (1362) may mean maintaining the first power control circuit (1351) and the second capacitor bank (1362) connected. For example, changing the capacitor filter based on the first reference range corresponding to the first capacitor bank (1361) may include disconnecting the first power control circuit (1351) and the second capacitor bank (1362), connecting the first power control circuit (1351) and the first capacitor bank (1361), and connecting the battery (189) and the second capacitor bank (1362).
