[0036] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components separate from each other (e.g., multiple chips). The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0037] Wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (such as new radio (NR) access technologies).

[0038] Antenna module 197 can transmit or receive signals or power to or from the exterior of electronic device 101 (e.g., external electronic device).

According to an embodiment, additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally incorporated into antenna module 197.

[0039] According to various embodiments, antenna module 197 may form a millimeter-wave antenna module.

[0040] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via inter-peripheral communication schemes (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0041] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199. Each of electronic device 102 or electronic device 104 can be a device of the same type as electronic device 101, or a device of a different type. According to an embodiment, all or some operations that would be performed on electronic device 101 can be performed on one or more of external electronic devices 102, external electronic devices 104, or server 108. For example, if electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, one or more external electronic devices may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 101. Electronic device 101 may provide the result as at least a partial response to the request, with or without further processing of the result. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used.

[0042] Figure 2a and Figure 2b This is a diagram used to describe envelope tracking (ET) mode and average power tracking (APT) mode. In electronic devices (e.g., Figure 1In the electronic device 101, the current consumed by the power amplifier (PA) affects the battery life of the user of the electronic device 101. Various technologies are being used to reduce the current consumption of the power amplifier. Furthermore, with the increase in peak-to-average power ratio (PAPR) due to the introduction of communication technologies using OFDM (e.g., LTE or NR), high efficiency is required. To reduce the current consumption of the power amplifier while meeting high efficiency requirements, the electronic device 101 can power the power amplifier using the ET method or the APT method via a power supply module.

[0043] refer to Figure 2a Examples of power supply circuits operable in ET or APT modes are described as at least a portion of the power supply module. The power supply circuit may include a boost converter circuit 220, a buck converter circuit 225, a linear regulator 230, an APT switch 241, and a capacitor 242. Battery voltage 211 may be supplied to the boost converter circuit 220. The buck converter circuit 225 used to describe embodiments of the present disclosure may include circuitry configured to perform a voltage drop during DC-DC conversion. In addition to buck converter circuitry, terms such as buck circuit, buck block, buck converter block, buck-type converter, buck-type circuit, buck-type block, or large buck converter and / or terms with equivalent technical / functional meanings may be used to refer to buck converter circuit 225. The boost converter circuit 220 used to describe embodiments of the present disclosure may include circuitry configured to perform a voltage increase during DC-DC conversion. In addition to boost converter circuits, terms such as boost circuit, boost block, boost converter block, boost converter, boost circuit or boost block and / or terms with equivalent technical / functional meanings may be used to refer to boost converter circuits.

[0044] refer to Figure 2aIn the first example 201, the power supply circuit can operate in ET mode. ET is a technique for supplying power to a power amplifier by means of an amplitude corresponding to the envelope of the transmitted signal. In the first example 201, the linear regulator 230 can operate. Terms such as ET state, ET operation, ET method, envelope reference mode, envelope check mode, or envelope usage mode, and / or terms with equivalent technical / functional meanings, other than ET mode, can be used to refer to ET mode. In ET mode, the linear regulator 230 can use the envelope of the signal output from the RF transceiver as input. The linear regulator 230 can be configured to amplify the envelope. The boost converter circuit 220 can be configured to output a regulator voltage 212 and a buck converter voltage 213 based on the battery voltage 211. The output of the linear regulator 230 can be connected to the output of the buck converter circuit 225. The buck converter circuit 225 can output a supply voltage 251 Vcc according to ET mode based on the battery voltage 211 and the buck converter voltage 213. The output of linear regulator 230 can be electrically connected to the output of buck converter circuit 225. The supply voltage 251 according to ET mode can be determined based on the output of linear regulator 230. APT switch 241 can be disconnected in ET mode. The power supply circuit can provide the supply voltage 251 according to ET mode to the power amplifier. The supply voltage 251 according to ET mode can be applied to the power amplifier.

[0045] In the second example 203, the power supply circuit can operate in APT mode. APT is a technique that supplies power to a power amplifier at a specified amplitude via a DC-DC converter. In the second example 203, the linear regulator 230 may not operate. Terms such as AT state, AT operation, AT method, fixed voltage mode, or fixed power mode, and / or terms with equivalent technical / functional meanings, other than APT mode, may be used to refer to APT mode. Boost converter circuit 220 can be configured to output buck converter voltage 213 based on battery voltage 211. Buck converter circuit 225 can output a supply voltage 252 Vcc according to APT mode based on battery voltage 211 and buck converter voltage 213. In APT mode, APT switch 241 can be closed. APT switch 241 can electrically connect capacitor 242 to the output of buck converter circuit 225. The supply voltage 252 according to APT mode may be affected by capacitor 242. DC voltage is generated by buck converter circuit 225, and capacitor 242 can be used to maintain a constant voltage. Through capacitor 242, the supply voltage 252 according to the APT mode can have a constant amplitude, as described later. Figure 2b As shown in the example, the power supply circuit can provide a supply voltage 252 according to the APT mode to the power amplifier. The supply voltage 252 according to the APT mode can be applied to the power amplifier.

[0046] refer to Figure 2b Figure 260 shows the voltage amplitude 250 corresponding to the transmitted signal and the battery voltage 213. Figure 270 shows the voltage amplitude 250 corresponding to the transmitted signal and the supply voltage 252 according to APT mode. Figure 280 shows the voltage amplitude 250 corresponding to the transmitted signal and the supply voltage 251 according to ET mode. When comparing Figures 260 and 270, since the difference between the supply voltage and the required voltage is smaller in APT mode, the current consumption when supplying the supply voltage 252 according to APT mode may be less than the current consumption when supplying the battery voltage 213 as is. When comparing Figures 270 and 280, the difference between the supply voltage and the required voltage in ET mode may be less than the difference between the supply voltage and the required voltage in APT mode. However, in ET mode, the linear regulator 230 may consume additional power. In terms of power consumption and efficiency, ET mode may be superior to APT mode, or APT mode may be superior to ET mode. According to an embodiment of the present disclosure, the electronic device 101 can control the power supply module to provide a supply voltage 251 according to the ET mode or a supply voltage 252 according to the APT mode to the power amplifier.

[0048] refer to Figure 3 Electronic device 101 may include processor 310, RF transceiver 320, RFFE module 340, power supply module 350, and antenna 380.

For example, processor 310 may include an AP and a CP. For example, processor 310 may include an AP. For example, processor 310 may include a CP.

According to an embodiment, RF transceiver 320 may control at least a portion of RFFE module 340 and / or power supply module 350 via Mobile Industrial Processor Interface (MIPI).

[0050] Electronic device 101 may include RFFE module 340 to support various frequency bands. For example, electronic device 101 may include a first RFFE module 341, a second RFFE module 342, a third RFFE module 343, a fourth RFFE module 344, and / or a fifth RFFE module 345.

The fourth RFFE module 344 may be connected to a fourth antenna 384. The fifth RFFE module 345 can be connected to the fifth antenna 385. Figure 3The present disclosure illustrates an RFFE module including a power amplifier for the transmit path, but embodiments thereof are not limited thereto. For example, as an example of an RFFE module, an RFFE module may use not only a PAMid including a transmit path, but also an LPAMid further including components for the receive path (e.g., a low-noise amplifier (LNA)). According to embodiments of the present disclosure, a module including a power amplifier to which it is supplied power according to ET mode (e.g., supply voltage 251) or according to APT mode (e.g., supply voltage 252) can be understood as an RFFE module of electronic device 101. Furthermore, for example, according to an embodiment, an RFFE module can be understood to include not only a single module, but also a power amplifier and an RFFE module.

[0051] Electronic device 101 may include a power supply module 350. The power supply module 350 may be controlled by processor 120 and / or RF transceiver 320. The power supply module 350 may be configured to supply power to multiple RFFE modules (e.g., RFFE module 340). The power supply module 350 may supply multiple powers to the multiple RFFE modules. The power supply module 350 may supply power to each of the multiple RFFE modules. For example, the power supply module 350 may be in the form of a module (or IC) in which multiple modulators are implemented. Supplying power to an RFFE module may be represented as applying a supply voltage to the PA of the RFFE module. The power supply module 350 may output multiple supply voltages for the multiple RFFE modules. For example, the power supply module 350 may output a first supply voltage 351 and a second supply voltage 352. For example, the first supply voltage 351 may be provided to a first RFFE module 341, a third RFFE module 343, and a fourth RFFE module 344. For example, the second supply voltage 351 can be provided to the second RFFE module 342, the third RFFE module 343, and the fourth RFFE module 344.

[0052] The first RFFE module 341 can obtain a first transmit signal 321 from the RF transceiver 320. The first RFFE module 341 can amplify the first transmit signal 321 via a first PA 361. A first supply voltage 351 can be applied to the first PA 361 for its operation. The first transmit signal 321 amplified by the first PA 361 can be transmitted via a first antenna 381.

[0053] The second RFFE module 342 can obtain the second transmit signal 322 from the RF transceiver 320. The second RFFE module 342 can amplify the second transmit signal 322 via the second PA 362. A second supply voltage 352 can be applied to the second PA 362 for its operation. The second transmit signal 322 amplified by the second PA 362 can be transmitted via the second antenna 382.

[0054] The third RFFE module 343 can obtain the third transmit signal 323 from the RF transceiver 320. The third RFFE module 343 can amplify the third transmit signal 323 via the third PA 363. For example, a first supply voltage 351 can be applied to the third PA 363 for its operation. For example, the third RFFE module 343 can be used for satellite communication. For the high transmit power of satellite communication, the electronic device 101 can apply both the first supply voltage 351 and the second supply voltage 352 to the third PA 363. For example, the electronic device 101 can operate the third PA 363 by electrically connecting the wiring for the second supply voltage 352 to the wiring for the first supply voltage 351 via a switch 393. The third transmit signal 323 amplified by the third PA 363 can be transmitted via the third antenna 383.

[0055] The fourth RFFE module 344 can obtain a fourth transmit signal 324 from the RF transceiver 320. The fourth RFFE module 342 can amplify the fourth transmit signal 3214 via the fourth PA 364. A first supply voltage 351 or a second supply voltage 352 can be applied to the fourth PA 364 for its operation. For example, the fourth RFFE module 344 may include a switch 394. The switch 394 can be configured to selectively connect either wiring for the first supply voltage 351 or wiring for the second supply voltage 352 to the fourth PA 364. The switch 394 can be operated under the control of the processor 310 or the RF transceiver 320. Depending on the operation of the switch 394, either the first supply voltage 351 or the second supply voltage 352 can be applied to the fourth PA 364. The fourth transmit signal 324 amplified by the fourth PA 364 can be transmitted via the fourth antenna 384.

[0056] The fifth RFFE module 345 can obtain the fifth transmit signal 325 from the RF transceiver 320. The fifth RFFE module 343 can amplify the fifth transmit signal 321 via the fifth PA 365. A first supply voltage 351 or a second supply voltage 352 can be applied to the fifth PA 365 for its operation. The processor 310 can apply the first supply voltage 351 to the fourth PA 364 or the second supply voltage 352 to the fourth PA 364 by controlling the switch 394. For example, wiring for powering the fifth PA 365 can be connected to the switch 394 of the fourth RFFE module 344. The switch 394 can be configured to selectively connect either the wiring for the first supply voltage 351 or the wiring for the second supply voltage 352 to the fifth PA 365. The switch 394 can be operated according to the control of the processor 310 or the RF transceiver 320. Depending on the operation of switch 394, the first supply voltage 351 can be applied to the fifth PA 365, or the second supply voltage 352 can be applied to the fifth PA 365.

[0057] According to an embodiment, the power (or voltage / current) of the power supply module 350 can be supplied based on ET mode or APT mode. The power supply module 350 can obtain information about the envelope waveform (e.g., envelope waveform signal 329) from the RF transceiver 320 to output a supply voltage according to ET mode. The processor 310 can control the RF transceiver 320 to provide the envelope waveform signal 329 to the power supply module 350. The envelope waveform signal 329 can be associated with the input signal of a power amplifier (PA) to which a supply voltage according to ET mode is applied. For a description of ET mode and APT mode, refer to... Figures 2a to 2b The power supply module 350 of the electronic device 101 may include multiple power supply circuits for multiple supply voltages. Here, each of the multiple power supply circuits may be referred to as the core, power supply block, power circuit, buck-boost circuit, operating power supply circuit, DC supply circuit, and / or equivalent technical terms of the power supply module 350. Each power supply circuit may output a supply voltage (e.g., a first supply voltage 351 or a second supply voltage 352). For example, the power supply module 350 of the electronic device 101 may output the first supply voltage 351 based on ET mode or based on APT mode. For example, the power supply module 350 of the electronic device 101 may output the second supply voltage 352 based on ET mode or based on APT mode.

[0058] If each power supply circuit of power supply module 350 supports ET mode, then each power supply circuit may include a linear regulator. For example, each power supply circuit of power supply module 350 may be... Figure 2aThe power supply circuit of the first example 201. According to the switch from the first example 201 to the second example 203, the power supply circuit capable of supporting ET mode can also support APT mode. As an example, due to technical limitations, ET may not be supported in approximately 100 MHz bandwidth (e.g., the NR bandwidth in EUTRA-NR(EN)-Dual Connection (DC)). In the example, the linear regulator of the power supply circuit operating in APT mode becomes unnecessary and results in wasted installation space. If each power supply circuit of the power supply module 350 only supports APT mode, then each power supply circuit may not include a linear regulator. For example, each power supply circuit of the power supply module 350 could be... Figure 2a The power supply circuit of the second example 203. In this case, although current consumption can be reduced based on ET mode, excessive current may be consumed due to the operation of APT mode. Based on the above problems, in order to reduce current consumption and improve the efficiency of the installation area, the structure and operation of the power supply module 350 for providing supply voltage according to ET mode and supply voltage according to APT mode are described in this disclosure.

[0059] Figures 4a to 4b This refers to a power supply module that includes switching circuitry (e.g., Figure 3 Examples of power supply modules 350. The power supply module 350 according to embodiments of this disclosure may include multiple power supply circuits. In this disclosure, power supply circuits are examples of units used to represent outputs, and no distinction is made between physical areas or the structure of limiting circuits within the power supply module 350. Figure 4a In the middle, it is described that Figure 3 An example of the power supply module 350 supplying a first supply voltage 351 to the first PA 361 of the first RFFE module 341 and a second supply voltage 352 to the second PA 362 of the second RFFE module 342.

[0060] refer to Figure 4aThe power supply module 350 may include a first power supply circuit 401, a second power supply circuit 402, a linear regulator 430, and a switching circuit 440. The first power supply circuit 401 may include a first boost converter circuit 420 and a first buck converter circuit 425. The first boost converter circuit 420 may output a regulated voltage 412 as a boost voltage to power the linear regulator 430. The first boost converter circuit 420 may output a first buck converter voltage 413 as a boost voltage to power the first buck converter circuit 425. The first buck converter voltage 413 may be input to the first buck converter circuit 425. The first boost converter circuit 420 may output the regulated voltage 412 and the first buck converter voltage 413 based on the battery voltage 411. For example, the first boost converter circuit 420, as a DC-DC converter, can output the regulated voltage 412 and the first buck converter voltage 413 by boosting the battery voltage 411. The regulated voltage 412 may be supplied to the linear regulator 430. The first buck converter voltage 413 can be supplied to the first buck converter circuit 425. The second power supply circuit 402 may include a second boost converter circuit 470 and a second buck converter circuit 475. The second boost converter circuit 470 can output a second buck converter voltage 463 as a boost voltage based on the battery voltage 411 to power the second buck converter circuit 475. For example, the second boost converter circuit 470, as a DC-DC converter, can output the second buck converter voltage 463 by boosting the battery voltage 411, and the second buck converter voltage 463 is the input voltage of the second buck converter circuit 475. The second buck converter voltage 463 can be supplied to the second buck converter circuit 475.

[0061] In an embodiment, the power supply module 350 may include multiple power supply ports to supply multiple powers. For example, the power supply module 350 may include a first power supply port 491 and a second power supply port 492. The first power supply port 491 may be configured to output a first supply voltage 351. The first supply voltage 351 may be applied to a first power supply amplifier (PA) 361. The second power supply port 492 may be configured to output a second supply voltage 352. The second supply voltage 352 may be applied to a second power supply amplifier (PA) 362.

[0062] Linear regulator 430 can operate based on the regulated voltage 412 of the first boost converter circuit 420. Linear regulator 430 can be configured to amplify the envelope waveform signal 329. Linear regulator 430 can amplify the envelope waveform signal 329 based on the regulated voltage 412. The amplified output of linear regulator 430 can be connected to switching circuit 440. Switching circuit 440 can be configured to selectively connect the output of linear regulator 430 to either the first power supply circuit 401 or the second power supply circuit 402. For example, switching circuit 440 can selectively connect the output of linear regulator 430 to either the output 426 of the first power supply circuit 401 or the output 476 of the second power supply circuit 402. For example, while the output of linear regulator 430 is connected to the first power supply circuit 401, the output of linear regulator 430 may not be connected to the second power supply circuit 402. For example, while the output of the linear regulator 430 is connected to the second power supply circuit 402, the output of the linear regulator 430 may not be connected to the first power supply circuit 401. As an example, the switching circuit 440 may be a single-pole double-throw (SPDT). Pole 441 of the switching circuit 440 may be electrically connected to either the first throw 442a or the second throw 442b. Throw 441 may be electrically connected to the output of the linear regulator 430. The first throw 442a may be electrically connected to the output 426 of the first power supply circuit 401 via the first supply line 443a. The second throw 442b may be electrically connected to the output 476 of the second power supply circuit 402 via the second supply line 443b.

[0063] Since the output of the linear regulator 430 is connected to only one of the two power supply circuits (e.g., the first power supply circuit 401 or the second power supply circuit 402) via the switching circuit 440, the power according to the ET mode can be selectively supplied to either the first PA 361 or the second PA 362. Based on the ET mode, only one of the first supply voltage 351 and the second supply voltage 352 can be generated. For example, when the supply voltage according to the ET mode is applied to the second PA 362, the first PA 361 can be disabled, or it can be supplied with the supply voltage according to the APT mode. Similarly, when the supply voltage according to the ET mode is applied to the first PA 361, the second PA 362 can be disabled, or it can be supplied with the supply voltage according to the APT mode.

[0064] According to an embodiment, in a first state, the switching circuit 440 can connect the output of the linear regulator 430 to the first power supply circuit 401. In the first state, the first power supply circuit 401 can generate a first supply voltage 351 according to the ET mode based on the linear regulator 430. The ET mode can be used to reduce efficiency degradation due to high PAPR. For example, in the ET mode, the first power supply circuit 401 can generate the first supply voltage 351 as a bias voltage for the first PA 361 based on tracking the amplitude of the RF signal associated with the first PA 361. The bias voltage can be determined based on the envelope of the RF signal (e.g., instantaneous output voltage). In the first state, the second power supply circuit 402 can generate a second supply voltage 352 according to the APT mode without the linear regulator 430. The APT mode can be used to reduce unnecessary power consumption of the power amplifier (e.g., the second PA 362). For example, in the APT mode, the second power supply circuit 402 can generate a second supply voltage 352 corresponding to the average output voltage of the second PA 362. Although Figure 4a Not shown, but in the first state, the second power supply circuit 402 can be electrically connected to an external passive component (e.g., capacitor 242) via an APT switch (e.g., APT switch 241) to generate a second supply voltage 352 according to the APT mode. According to an embodiment, in the first state, the power supply module 350 can be configured to provide a second supply voltage 351 to the second PA 362 based on the APT mode using the second power supply circuit 402, while simultaneously providing a first supply voltage 351 to the first PA 361 based on the ET mode using the first power supply circuit 401 and the linear regulator 430.

[0065] According to an embodiment, in the second state, the switching circuit 440 can connect the output of the linear regulator 430 to the second power supply circuit 402. In the second state, the second power supply circuit 402 can generate a second supply voltage 352 according to the ET mode based on the linear regulator 430. At this time, the linear regulator 430 can receive a regulated voltage 412 from the first boost converter circuit 420 of the first power supply circuit 401. In the second state, the first power supply circuit 401 can generate a first supply voltage 351 according to the APT mode. Although Figure 4aNot shown, but in the second state, the first power supply circuit 401 can be electrically connected to an external passive component (e.g., capacitor 242) via an APT switch (e.g., APT switch 241) to generate a first supply voltage 351 according to the APT mode. According to an embodiment, in the second state, the power supply module 350 can be configured to provide a second supply voltage 351 to the second PA 362 based on the ET mode using the second power supply circuit 402 and the linear regulator 430, while simultaneously providing a first supply voltage 351 to the first PA 361 based on the APT mode using the first power supply circuit 401.

[0066] The power supply module 350 may include an envelope input port 480 for the envelope waveform signal 329. Since the power supply module 350 includes a linear regulator 430 for two power supply circuits (e.g., a first power supply circuit 401 and a second power supply circuit 402), wiring for the envelope input signal 329 (hereinafter referred to as control lines) can be provided between the power supply module 350 and the RF transceiver 320. According to an embodiment, the envelope waveform signal 329 can vary depending on whether the switching circuit 440 is in a first state or a second state. For example, in the first state, a first envelope waveform signal can be provided from the RF transceiver 320 to the power supply module 350 via the envelope input port 480. The first envelope waveform signal can be associated with a transmit signal input to the first PA 361, such that a voltage according to the ET mode is provided to the first PA 361. In the second state, a second envelope waveform signal can be provided from the RF transceiver 320 to the power supply module 350 via the envelope input port 480. The second envelope waveform signal can be associated with the transmit signal input to the second PA 362, such that the voltage according to the ET mode is provided to the second PA 362.

[0067] refer to Figure 4b ,Apart from Figure 4aIn addition to the circuitry shown, electronic device 101 may also include various passive components for powering the circuitry. According to an embodiment, electronic device 101 may include inductors. For example, electronic device 101 may include a first inductor 493a. The first inductor 493a may be connected to a first buck converter circuit 425. The output of the first buck converter circuit 425 may be provided to a first power supply port 491 via the first inductor 493a. For example, electronic device 101 may include a second inductor 493b. The second inductor 493b may be connected to a second buck converter circuit 475. The output of the second buck converter circuit 475 may be provided to a second power supply port 492 via the second inductor 493b. According to an embodiment, electronic device 101 may include capacitors 482a, 483a, and 483b. For example, capacitor 482a may be connected to the output of a first boost converter circuit 420 that supplies voltage 412 to the regulator. For example, capacitor 483a may be connected to the output of a first boost converter circuit 420 that supplies voltage 413 to the first buck converter. For example, capacitor 483b can be connected to the output of the second boost converter circuit 470 that supplies the second buck converter voltage 463.

[0068] According to an embodiment, electronic device 101 may include switches and passive components as components in APT mode. For example, electronic device 101 may include a first APT switch 494a and a first capacitor 495a. The first APT switch 494a can be connected to output 426 via a first supply line 443a. When the first boost circuit 420 and the first buck converter circuit 425 are operating in APT mode, the first APT switch 494a can electrically connect the first capacitor 495a to output 426. For example, the first APT switch 494a may be in a closed state. For example, electronic device 101 may include a second APT switch 494b and a second capacitor 495b. The second APT switch 494b can be electrically connected to output 476 via a second supply line 443b. When the second boost circuit 470 and the second buck converter circuit 475 are operating in APT mode, the second APT switch 494b can electrically connect the second capacitor 495b to output 476. For example, the second APT switch 494b may be in a closed state.

[0069] exist Figures 4a to 4b Examples of supplying power to the first power amplifier 361 and the second power amplifier 362 have been described, but embodiments of this disclosure are not limited thereto. Figure 3As shown, the power supply module 350 can be configured to supply power not only to the two RFFE modules (e.g., the first RFFE module 341 and the second RFFE module 342), but also to other RFFE modules (e.g., the third RFFE module 343, the fourth RFFE module 344 and the fifth RFFE module 345).

[0070] Despite Figure 4b The diagram shows the switches and passive components required to describe the detailed operation of each circuit, but... Figure 4b The circuits shown are merely examples and should not be construed as limiting other embodiments of this disclosure. In the following, when using… Figures 5a to 8b When describing components according to embodiments of this disclosure, the circuitry for power supply may be shown by omitting passive components and APT switches.

[0072] refer to Figure 5a and Figure 5bThe power supply module 350 may include a first power supply circuit 401, a second power supply circuit 402, a linear regulator 430, and a switching circuit 440. The first power supply circuit 401 may include a first boost converter circuit 420 and a first buck converter circuit 425. The first boost converter circuit 420 may output a regulated voltage 412 as a boost voltage to power the linear regulator 430. The first boost converter circuit 420 may output a first buck converter voltage 413 as a boost voltage to power the first buck converter circuit 425. The first buck converter voltage 413 may be input to the first buck converter circuit 425. The first boost converter circuit 420 may output the regulated voltage 412 and the first buck converter voltage 413 based on the battery voltage 411. The regulated voltage 412 may be provided to the linear regulator 430. The first buck converter voltage 413 may be provided to the first buck converter circuit 425. The second power supply circuit 402 may include a second boost converter circuit 470 and a second buck converter circuit 475. The second boost converter circuit 470 can output a second buck converter voltage 463 as a boost voltage based on the battery voltage 411, to be used as power for the second buck converter circuit 475. The second buck converter voltage 463 can be supplied to the second buck converter circuit 475.

[0073] The linear regulator 430 can operate based on the regulated voltage 412 of the first boost converter circuit 420. The linear regulator 430 can be configured to amplify the envelope waveform signal 329. The switching circuit 440 can be configured to selectively connect the output of the linear regulator 430 to either the first power supply circuit 401 or the second power supply circuit 402. Since the output of the linear regulator 430 is connected to only one of the two power supply circuits (e.g., the first power supply circuit 401 or the second power supply circuit 402) via the switching circuit 440, only one of the first supply voltage 351 and the second supply voltage 352 can be generated based on ET mode.

[0074] refer to Figure 5aWhen a voltage according to the ET mode (e.g., a first supply voltage 351) is to be supplied to the first PA 361, the electronic device 101 (e.g., processor 310) can control the switching circuit 440 such that the output of the linear regulator 430 is connected to the output 426 of the first power supply circuit 401. The switching circuit 440 can operate in a first state. In the first state, the switching circuit 440 can connect the output of the linear regulator 430 to the output 426 of the first power supply circuit 401. The switching circuit 440 can be configured to disconnect the output of the linear regulator 430 from the output 476 of the second power supply circuit 402 while the output of the linear regulator 430 is connected to the output 426 of the first power supply circuit 401. In the first state, the first power supply circuit 401 can generate the first supply voltage 351 according to the ET mode based on the output of the linear regulator 430. In the first state, the second power supply circuit 402 can generate a second supply voltage 352 according to the APT mode via the second boost converter circuit 470 and the second buck converter circuit 475. In APT mode, an APT switch (e.g., a second APT switch 494b) and at least one passive component connected via the APT switch (e.g., an external capacitor or a second capacitor 495b) can be used to maintain the output voltage of the second buck converter circuit 475 within a certain range without fluctuation. According to an embodiment, in a first state, the power supply module 350 can be configured to provide a second supply voltage 351 to the second PA 362 using the second power supply circuit 402 in APT mode, while simultaneously providing a first supply voltage 351 to the first PA 361 using the first power supply circuit 401 and the linear regulator 430 in ET mode.

[0075] refer to Figure 5bWhen a voltage according to the ET mode (e.g., the second supply voltage 352) is to be supplied to the second PA 361, the electronic device 101 (e.g., the processor 310) can control the switching circuit 440 such that the output of the linear regulator 430 is connected to the output 476 of the second power supply circuit 402. The switching circuit 440 can operate in a second state. In the second state, the switching circuit 440 can connect the output of the linear regulator 430 to the output 476 of the second power supply circuit 402. The switching circuit 440 can be configured to disconnect the output of the linear regulator 430 from the output 426 of the first power supply circuit 401 while the output of the linear regulator 430 is connected to the output 476 of the second power supply circuit 402. In the second state, the first power supply circuit 401 can generate the second supply voltage 352 according to the APT mode via the first boost converter circuit 420 and the first buck converter circuit 425. In APT mode, an APT switch (e.g., first APT switch 494a) and at least one passive component connected via the APT switch (e.g., an external capacitor or first capacitor 495a) can be used to maintain the output voltage of the first buck converter circuit 425 within a certain range without fluctuation. In the second state, the second power supply circuit 402 can generate a second supply voltage 352 according to ET mode based on the output of the linear regulator 430. According to an embodiment, in the second state, the power supply module 350 can be configured to provide a first supply voltage 351 to the first PA 361 based on APT mode using the first power supply circuit 401, while simultaneously providing a second supply voltage 352 to the second PA 362 based on ET mode using the second power supply circuit 402 and the linear regulator 430.

[0076] Figures 6a to 6b This indicates that the power supply module is controlled according to the transmission power (e.g., Figure 3 , Figure 4a , Figure 4b , Figure 5a and Figure 5b The switching circuit of the power supply module 350 (e.g., Figure 4a , Figure 4b , Figure 5a and Figure 5b Example of the switching circuit 440. For a description of the structure, function, and operation of the power supply module 350, please refer to... Figure 3 , Figure 4a , Figure 4b , Figure 5a and Figure 5b The description is as follows. For a description of the structure, function, and operation of the switching circuit 440, please refer to... Figure 4a , Figure 4b , Figure 5a and Figure 5b The description.

[0077] refer to Figure 6a and Figure 6b The power supply module 350 may include a first power supply circuit 401, a second power supply circuit 402, a linear regulator 430, and a switching circuit 440. The first power supply circuit 401 may include a first boost converter circuit 420 and a first buck converter circuit 425. The first boost converter circuit 420 may output a regulated voltage 412 as a boost voltage to power the linear regulator 430. The first boost converter circuit 420 may output a first buck converter voltage 413 as a boost voltage to power the first buck converter circuit 425. The first buck converter voltage 413 may be input to the first buck converter circuit 425. The first boost converter circuit 420 may output the regulated voltage 412 and the first buck converter voltage 413 based on the battery voltage 411. The regulated voltage 412 may be provided to the linear regulator 430. The first buck converter voltage 413 may be provided to the first buck converter circuit 425. The second power supply circuit 402 may include a second boost converter circuit 470 and a second buck converter circuit 475. The second boost converter circuit 470 can output a second buck converter voltage 463 as a boost voltage based on the battery voltage 411, to be used as power for the second buck converter circuit 475. The second buck converter voltage 463 can be supplied to the second buck converter circuit 475.

[0078] Linear regulator 430 can be configured to amplify the envelope waveform signal 329. Switching circuit 440 can be configured to selectively connect the output of linear regulator 430 to either the first power supply circuit 401 or the second power supply circuit 402. Since the output of linear regulator 430 is connected to only one of the two power supply circuits (e.g., the first power supply circuit 401 or the second power supply circuit 402) via switching circuit 440, only one of the first supply voltage 351 and the second supply voltage 352 can be generated based on the ET mode. Which power supply circuit should generate the voltage according to the ET mode can be determined based on the power of the power amplifier. For example, each power supply circuit can operate based on the power range of the power amplifier. Since the transmitted signal of the power amplifier has higher power, the supply voltage according to the ET mode is more advantageous as a bias voltage than the supply voltage according to the APT mode. If the supply voltage according to the APT mode is provided to the power amplifier, the peak signal increases with increasing power, and therefore the amplitude of the bias voltage applied to the power amplifier inevitably increases. Due to the high amplitude of the bias voltage, a situation may occur in certain regions of the transmitted signal where an unnecessarily high voltage is supplied. Therefore, a supply voltage according to the ET mode can be provided for the power amplifier corresponding to the high-power transmission signal in the two transmission signals.

[0079] Electronic device 101 (e.g., processor 310) can obtain information corresponding to a first power of a first transmitted signal. The first transmitted signal may be a signal transmitted via a first PA 361 and a first antenna 381. Electronic device 101 can obtain information corresponding to a second power of a second transmitted signal. The second transmitted signal may be a signal transmitted via a second PA 362 and a second antenna 382. Electronic device 101 can generate a supply voltage corresponding to the larger power between the first and second powers based on an ET mode by comparing the first power and the second power.

[0080] refer to Figure 6a In example 600 of the power supply module 350, the switching circuit 440 can be in a first state (e.g., Figure 4a , Figure 4b , Figure 5a and Figure 5b The system operates in the first state. Figure 610 shows the power of each transmitted signal. For example, the first power 611 of the first transmitted signal according to the first PA 361 may be greater than the second power 612 of the second transmitted signal according to the second PA 362. Electronic device 101 (e.g., processor 310) can confirm that the first power 611 is greater than the second power 612. Based on the confirmation that the first power 611 is greater than the second power 612, electronic device 101 (e.g., processor 310) can control the switching circuit 440 to operate in the first state. Electronic device 101 (e.g., processor 310) can control the switching circuit 440 such that the output of the linear regulator 430 is connected to the output 426 of the first power supply circuit 401. In the first state, the first power supply circuit 401 can generate a first supply voltage 351 according to the ET mode based on the output of the linear regulator 430. In the first state, the second power supply circuit 402 can generate a second supply voltage 352 according to the APT mode through the second boost converter circuit 470 and the second buck converter circuit 475. In APT mode, an APT switch (e.g., a second APT switch 494b) and at least one passive component connected via the APT switch (e.g., an external capacitor or a second capacitor 495b) can be used to maintain the output voltage of the second buck converter circuit 475 within a certain range without fluctuation.

[0081] refer to Figure 6b In example 650 of the power supply module 350, the switching circuit 440 can be in a second state (e.g., Figure 4a , Figure 4b , Figure 5a and Figure 5bThe system operates in the second state. Figure 660 represents the power of each transmitted signal. For example, the first power 611 of the first transmitted signal according to the first PA 361 may be less than the second power 612 of the second transmitted signal according to the second PA 362. Electronic device 101 (e.g., processor 310) can confirm that the second power 672 is greater than the first power 671. Based on the confirmation that the second power 612 is greater than the first power 611, electronic device 101 (e.g., processor 310) can control the switching circuit 440 to operate in the second state. Electronic device 101 (e.g., processor 310) can control the switching circuit 440 such that the output of the linear regulator 430 is connected to the output 476 of the second power supply circuit 402. In the second state, the second power supply circuit 402 can generate a second supply voltage 352 according to the ET mode based on the output of the linear regulator 430. In the second state, the first power supply circuit 401 can generate a second supply voltage 352 according to the APT mode via the first boost converter circuit 420 and the first buck converter circuit 425. In APT mode, an APT switch (e.g., a first APT switch 494a) and at least one passive component connected via the APT switch (e.g., an external capacitor or a first capacitor 495a) can be used to maintain the output voltage of the first buck converter circuit 425 within a certain range without fluctuation.

[0082] exist Figure 6a and Figure 6b An example has been described whereby the power of the transmitted signals of two power amplifiers is compared to provide a voltage according to the ET mode to one power amplifier and a voltage according to the APT mode to the other power amplifier.

[0083] At the same time, with Figures 6a to 6b The differences described herein are not simply a comparison of two powers, but rather a distinction between high and low (or medium) power by confirming whether the power of each transmitted signal is greater than a power threshold. For example, electronic device 101 (e.g., processor 310) can confirm that a first power of a first transmitted signal is greater than a power threshold. Electronic device 101 can confirm that a second power of a second transmitted signal is less than or equal to a power threshold. Electronic device 101 can output a first supply voltage 351 according to ET mode as a bias voltage for a power amplifier (e.g., first PA 361) corresponding to a first power greater than the power threshold. Electronic device 101 can output a second supply voltage 352 according to APT mode as a bias voltage for a power amplifier (e.g., second PA 362) corresponding to a second power less than or equal to the power threshold. If both powers are greater than the power threshold or both powers are less than the power threshold, electronic device 101 can determine the power to be supplied according to APT mode and the power to be supplied according to ET mode by comparing the two powers, as shown below. Figures 6a to 6b As described in [the text].

[0084] Figures 7a to 7b This indicates that the power supply module is controlled according to the bandwidth (e.g., Figure 3 , Figure 4a , Figure 4b , Figure 5a and Figure 5b The switching circuit of the power supply module 350 (e.g., Figure 4a , Figure 4b , Figure 5a and Figure 5b Example of the switching circuit 440. For a description of the structure, function, and operation of the power supply module 350, please refer to... Figure 3 , Figure 4a , Figure 4b , Figure 5a and Figure 5b The description is as follows. For a description of the structure, function, and operation of the switching circuit 440, please refer to... Figure 4a , Figure 4b , Figure 5a and Figure 5b The description.

[0085] refer to Figure 7a and Figure 7b The power supply module 350 may include a first power supply circuit 401, a second power supply circuit 402, a linear regulator 430, and a switching circuit 440. The first power supply circuit 401 may include a first boost converter circuit 420 and a first buck converter circuit 425. The first boost converter circuit 420 may output a regulated voltage 412 as a boost voltage to power the linear regulator 430. The first boost converter circuit 420 may output a first buck converter voltage 413 as a boost voltage to power the first buck converter circuit 425. The first buck converter voltage 413 may be input to the first buck converter circuit 425. The first boost converter circuit 420 may output the regulated voltage 412 and the first buck converter voltage 413 based on the battery voltage 411. The regulated voltage 412 may be provided to the linear regulator 430. The first buck converter voltage 413 may be provided to the first buck converter circuit 425. The second power supply circuit 402 may include a second boost converter circuit 470 and a second buck converter circuit 475. The second boost converter circuit 470 can output a second buck converter voltage 463 as a boost voltage based on the battery voltage 411, to be used as power for the second buck converter circuit 475. The second buck converter voltage 463 can be supplied to the second buck converter circuit 475.

[0086] Linear regulator 430 can operate based on the first boost converter circuit 420 of the first power supply circuit 401. For example, linear regulator 430 can be configured to amplify the envelope waveform signal 329 based on the regulator voltage 412 of the first boost converter circuit 420. Even when linear regulator 430 operates through the first boost converter circuit 420, the output of linear regulator 430 can be connected to the output 426 of the first power supply circuit 401 or the output 476 of the second power supply circuit 402. Switching circuit 440 can be configured to selectively connect the output of linear regulator 430 to either the first power supply circuit 401 or the second power supply circuit 402. Therefore, even if the first PA 361 is disabled, the second PA 362 can use the supply voltage according to the APT mode or the supply voltage according to the ET mode as the bias voltage. Meanwhile, due to design constraints, linear regulators (e.g., linear regulator 430) are not easily amplified signals with a bandwidth greater than or equal to a specific bandwidth (e.g., approximately 60 MHz). Since a specific frequency band (e.g., the band of 5G NR) supports bandwidths greater than 60 MHz (e.g., approximately 100 MHz), the type of power to be supplied to the power amplifier for the transmitted signal can be determined based on the bandwidth of the transmitted signal. For example, if the bandwidth of the second transmitted signal of the second PA 362 is approximately 100 MHz, the second supply voltage 352 is difficult to generate based on ET mode, therefore the second supply voltage 352 should be generated based on APT mode. As another example, if the bandwidth of the second transmitted signal of the second PA 362 is approximately 20 MHz, the linear regulator 430 is available while the first PA 361 is disabled, therefore the second supply voltage 352 can be generated based on ET mode.

[0087] refer to Figure 7a In example 700 of the power supply module 350, the switching circuit 440 can be in a second state (e.g., Figure 4a , Figure 4b , Figure 5a and Figure 5bIn the second state, the first PA 361 can be disabled. Figure 710 shows the bandwidth 712 of the transmitted signal of the second PA 362. The electronic device 101 (e.g., processor 310) can confirm that the bandwidth 712 is less than a bandwidth threshold. When the first PA 361 is disabled, based on the confirmation that the bandwidth 712 is less than the bandwidth threshold, the electronic device 101 (e.g., processor 310) can control the switching circuit 440 to operate in the second state. The electronic device 101 (e.g., processor 310) can control the switching circuit 440 such that the output of the linear regulator 430 is connected to the output 476 of the second power supply circuit 402. In the second state, the second power supply circuit 402 can generate a second supply voltage 352 according to the ET mode based on the output of the linear regulator 430. In the second state, even if the output power of the first buck converter circuit 425 is supplied to the first PA 361 according to the APT mode, the disabled first PA 361 can not consume current. Furthermore, even when the first buck converter voltage 413 is present, no current is consumed if the buck converter circuit is disabled, and therefore no efficiency degradation due to power supply will occur.

[0088] refer to Figure 7b In example 750 of the power supply module 350, the switching circuit 440 can be in a first state (e.g., Figure 4a , Figure 4b , Figure 5a and Figure 5b In the first state, the first PA 361 can be disabled. Figure 760 shows the bandwidth 762 of the transmitted signal of the second PA 362. The electronic device 101 (e.g., processor 310) can confirm that the bandwidth 762 is greater than a bandwidth threshold. When the first PA 361 is disabled, based on the confirmation that the bandwidth 762 is greater than the bandwidth threshold, the electronic device 101 (e.g., processor 310) can control the switching circuit 440 to operate in the first state. The electronic device 101 (e.g., processor 310) can control the switching circuit 440 such that the output of the linear regulator 430 is connected to the output 426 of the first power supply circuit 401. In the second state, the second power supply circuit 402 can generate a second supply voltage 352 according to the APT mode. For example, in the second state, the first power supply circuit 401 and / or the linear regulator 430 can be disabled. Therefore, the decrease in power supply efficiency due to the disabled circuit may be negligible. For example, in the second state, even if power is supplied to the first PA 361, the disabled first PA 361 can still not consume current.

[0089] Figures 8a to 8b This indicates that the power supply module is controlled according to the bandwidth (e.g., Figure 3 , Figure 4a , Figure 4b , Figure 5a and Figure 5b The switching circuit of the power supply module 350 (e.g., Figure 4a , Figure 4b , Figure 5a and Figure 5b Example of the switching circuit 440.

Figure 3 , Figure 4a , Figure 4b , Figure 5a and Figure 5b The description is as follows. For a description of the structure, function, and operation of the switching circuit 440, please refer to... Figure 4a , Figure 4b , Figure 5a and Figure 5b The description.

[0090] refer to Figure 8a and Figure 8b The power supply module 350 may include a first power supply circuit 401, a second power supply circuit 402, a linear regulator 430, and a switching circuit 440. The first power supply circuit 401 may include a first boost converter circuit 420 and a first buck converter circuit 425. The first boost converter circuit 420 may output a regulated voltage 412 as a boost voltage to power the linear regulator 430. The first boost converter circuit 420 may output a first buck converter voltage 413 as a boost voltage to power the first buck converter circuit 425. The first buck converter voltage 413 may be input to the first buck converter circuit 425. The first boost converter circuit 420 may output the regulated voltage 412 and the first buck converter voltage 413 based on the battery voltage 411. The regulated voltage 412 may be provided to the linear regulator 430. The first buck converter voltage 413 may be provided to the first buck converter circuit 425. The second power supply circuit 402 may include a second boost converter circuit 470 and a second buck converter circuit 475. The second boost converter circuit 470 can output a second buck converter voltage 463 as a boost voltage based on the battery voltage 411, to be used as power for the second buck converter circuit 475. The second buck converter voltage 463 can be supplied to the second buck converter circuit 475.

[0091] The linear regulator 430 can operate based on the first boost converter circuit 420 of the first power supply circuit 401. For example, the linear regulator 430 can be configured to amplify the envelope waveform signal 329 based on the regulator voltage 412 of the first boost converter circuit 420. During the period when the second supply voltage 352 is applied to the second PA 362, the first supply voltage 351 can be applied as the bias voltage of the enabled first PA 361. Since the output of the linear regulator 430 is connected to only one of the two power supply circuits (e.g., the first power supply circuit 401 or the second power supply circuit 402) via the switching circuit 440, only one of the first supply voltage 351 and the second supply voltage 352 can be generated based on the ET mode. At the same time, due to the limitations of the linear regulator 430's capabilities, signals with a bandwidth greater than or equal to a certain bandwidth (e.g., approximately 60 MHz) are not easily amplified. Therefore, based on the bandwidth of the transmitted signal, the power amplifier to which power according to the ET mode should be supplied can be determined. According to an embodiment, electronic device 101 (e.g., processor 310) can determine a combination of frequency bands to be provided by power supply module 350. For example, in the case of dual-connectivity (DC) or uplink (UL) carrier aggregation (CA), the combination of frequency bands to be used for transmission can be determined by the RFFE module. Electronic device 101 can control switching circuit 440 based on a first bandwidth of a first frequency band and a second bandwidth of a second frequency band represented by the combination. For example, if the first bandwidth is less than a bandwidth threshold for the operation of linear regulator 430 and the second bandwidth is greater than or equal to the bandwidth threshold, electronic device 101 can control switching circuit 440 such that switching circuit 440 operates in a first state. For a detailed description of the structure of power supply module 350, refer to... Figure 8a For another example, if the second bandwidth is less than the bandwidth threshold for the operation of the linear regulator 430, and the first bandwidth is greater than or equal to the bandwidth threshold, then the electronic device 101 can control the switching circuit 440 such that the switching circuit 440 operates in the second state. For a detailed description of the power supply module 350, please refer to... Figure 8b .

[0092] refer to Figure 8a In example 800 of the power supply module 350, the switching circuit 440 can be in a first state (e.g., Figure 4a , Figure 4b , Figure 5a and Figure 5bThe system operates in the first state. Figure 810 shows the first bandwidth 811 of the first transmitted signal of the first PA 361 and the second bandwidth 812 of the second transmitted signal of the second PA 362. The horizontal axis of Figure 810 represents the frequency domain, and the wider the extension along the horizontal axis, the larger the bandwidth. For example, the first bandwidth 811 may be less than a bandwidth threshold (e.g., approximately 60 MHz). The second bandwidth 812 may be greater than a bandwidth threshold (e.g., approximately 60 MHz). Since envelope tracking (ET) for the second transmitted signal is difficult, the electronic device 101 (e.g., processor 310) may control the switching circuit 440 to operate in the first state. The electronic device 101 (e.g., processor 310) may control the switching circuit 440 such that the output of the linear regulator 430 is connected to the output 426 of the first power supply circuit 401. In the first state, the first power supply circuit 401 may generate a first supply voltage 351 according to the ET mode based on the output of the linear regulator 430. In the first state, the second power supply circuit 402 can generate a second supply voltage 352 according to the APT mode via the second boost converter circuit 470 and the second buck converter circuit 475. In the APT mode, the APT switch of the second power supply circuit 402 (e.g., the second APT switch 494b) and at least one passive component connected through the APT switch (e.g., an external capacitor or the second capacitor 495b) can be used to maintain the output voltage of the second buck converter circuit 475 within a certain range without fluctuation.

[0093] refer to Figure 8b In example 850 of the power supply module 350, the switching circuit 440 can be in a second state (e.g., Figure 4a , Figure 4b , Figure 5a and Figure 5bThe system operates in the second state. Figure 870 shows the first bandwidth 871 of the first transmitted signal of the first PA 361 and the second bandwidth 872 of the second transmitted signal of the second PA 362. The horizontal axis of Figure 870 represents the frequency domain, and the wider the extension along the horizontal axis, the larger the bandwidth. For example, the first bandwidth 871 may be greater than a bandwidth threshold (e.g., approximately 60 MHz). The second bandwidth 872 may be less than a bandwidth threshold (e.g., approximately 60 MHz). Since the ET for the first transmitted signal is difficult, the electronic device 101 (e.g., processor 310) may control the switching circuit 440 to operate in the second state. The electronic device 101 (e.g., processor 310) may control the switching circuit 440 such that the output of the linear regulator 430 is connected to the output 476 of the second power supply circuit 402. In the second state, the first power supply circuit 401 may generate a second supply voltage 352 according to the APT mode via the first boost converter circuit 420 and the first buck converter circuit 425. In APT mode, an APT switch (e.g., first APT switch 494a) and at least one passive component connected via the APT switch (e.g., an external capacitor or first capacitor 495a) can be used to maintain the output voltage of the first buck converter circuit 425 within a certain range without fluctuation. In the second state, the second power supply circuit 402 can generate a second supply voltage 352 according to ET mode based on the output of the linear regulator 430.

[0094] exist Figures 8a to 8b The present disclosure describes a situation where the bandwidth of one transmitted signal is greater than or equal to a bandwidth threshold and the bandwidth of another transmitted signal is less than the bandwidth threshold; however, the examples provided are not limited to this. For example, the bandwidth of the signal amplified by the power supply module 350 may all be less than the bandwidth threshold. According to an embodiment, the electronic device 101 (e.g., processor 310) can generate a power supply corresponding to a signal with a larger bandwidth in the signal based on an ET mode. For example, if the first bandwidth of the first transmitted signal of the first PA 361 is narrower than the second bandwidth of the second transmitted signal of the second PA 362 and the second bandwidth is less than the bandwidth threshold, the electronic device 101 (e.g., processor 310) can generate a second supply voltage 352 for the second transmitted signal based on an ET mode. The electronic device 101 can control the switching circuit 440 to operate in a second state. In the second state, the switching circuit 440 can connect the output of the linear regulator 430 to the second power supply circuit 402. While supplying the second supply voltage 352 for the second transmitted signal, the electronic device 101 can generate a first supply voltage 351 for the first transmitted signal based on an APT mode.

[0095] For example, the bandwidth of the signal amplified by the power supply module 350 may be entirely equal to or greater than the bandwidth threshold. Since the linear regulator 430 is difficult to operate with signals having bandwidths greater than or equal to the bandwidth threshold, the linear regulator 430 may not operate. According to an embodiment, the electronic device 101 may control the power supply module 350 such that the output of the linear regulator 430 is not connected to any buck converter circuit (e.g., the first buck converter circuit 425 or the second buck converter circuit 475). For example, the electronic device 101 may disable the switching circuit 440, which acts as an SPDT.

[0096] Since the disabled SPDT is in a floating state, the linear regulator 430 can be in a state where it is not electrically connected to any buck converter circuit (e.g., the first buck converter circuit 425 or the second buck converter circuit 475).

[0097] The power supply module 350 according to embodiments of the present disclosure can provide an RF system for simplifying the installation area and reducing the current consumption of the linear regulator by flexibly supplying power to multiple power amplifiers (e.g., a first supply voltage 351 and a second supply voltage 352) according to ET mode and / or APT mode. The effects obtainable from the present disclosure are not limited to those described above, and any other effects not mentioned herein will be clearly understood by those skilled in the art to which this disclosure pertains from the following description.

[0098] In one embodiment, an electronic device 101 is provided. The electronic device 101 may include a processor 310, a radio frequency (RF) transceiver 320, a first radio frequency front-end (RFFE) module including a first power amplifier 361, a second RFFE module including a second power amplifier 362, and a power supply module 350. The power supply module 350 includes a first power supply circuit 401 for the first power amplifier 361, a second power supply circuit 402 for the second power amplifier 362, a linear regulator 430, and a switching circuit 440.
