Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a voltage regulation circuit, method, apparatus, wireless communication device, and medium. Background Technology

[0002] With the upgrading of wireless Wi-Fi protocols, the transmission rate of wireless communication devices has been greatly improved. Correspondingly, the power consumption of wireless communication devices has also increased. However, the increase in power consumption will greatly affect the heat dissipation of wireless communication devices. Therefore, how to reduce the power consumption of wireless communication devices with high transmission rates is a technical problem that urgently needs to be solved.

[0003] Wireless communication devices, such as wireless routers, mainly consist of three parts: the main chip, front-end modules (FEMs), and antennas. They are primarily used for the conversion between digital signals and radio electromagnetic signals during signal transmission and reception. The FEM is the core component of the wireless communication device, accounting for over 60% of its total power consumption, with some of this power used for heat generation. In practical applications, the power consumption of the FEM decreases as its supply voltage decreases. However, a drop in supply voltage exacerbates the nonlinear amplification problem of the FEM, leading to a deterioration in the Error Vector Magnitude (EVM) index, which in turn degrades the performance of the wireless communication device, potentially even preventing it from meeting design requirements.

[0004] In related technologies, the FEM in wireless communication devices is usually powered by a single fixed power supply. After the wireless communication device is manufactured, its power consumption in the working state is basically constant. If the power consumption of the wireless communication device is reduced, its system performance will inevitably be reduced, thereby affecting the user experience of the end user. Summary of the Invention

[0005] This invention provides a voltage regulation circuit, method, apparatus, wireless communication device, and medium to achieve dynamic adjustment of the power consumption of the wireless communication device, thereby optimizing the system performance of the wireless communication device.

[0006] In a first aspect, embodiments of the present invention provide a voltage regulation circuit applied to a wireless communication device, the wireless communication device including at least one front-end module (FEM), and the voltage regulation circuit including a control module, a voltage regulation module, and a power supply module, wherein:

[0007] The control module is used to acquire the negotiation rate and connection status of the wireless communication device, and output a first control signal based on the negotiation rate and the connection status.

[0008] The voltage regulation module is used to receive the first control signal and, under the control of the first control signal, regulate the output voltage of the power supply module.

[0009] The power module is used to provide the regulated output voltage to the FEM.

[0010] This invention provides a voltage regulation circuit, including a control module, a voltage regulation module, and a power supply module. The control module acquires the negotiation rate and connection status of a wireless communication device, and outputs a first control signal based on the negotiation rate and connection status. The voltage regulation module receives the first control signal and, under its control, regulates the output voltage of the power supply module. The power supply module provides the regulated output voltage to the FEM (Flexible Encryptor). Because the output voltage supplying the FEM is adjusted according to the negotiation rate and connection status of the wireless communication device, dynamic processing of the power consumption of the wireless communication device is achieved, thereby optimizing the system performance of the wireless communication device and improving the user experience for end users.

[0011] In one optional embodiment, the control module is specifically used for:

[0012] If it is determined that the connection status is that a device is connected and the negotiation rate is greater than the preset negotiation rate, then a first control signal is output to adjust the output voltage to a first preset range.

[0013] If it is determined that the connection status is that a device is connected, and the negotiation rate is not greater than the preset negotiation rate, then a first control signal is output to adjust the output voltage to a second preset range.

[0014] In the circuit described above, after acquiring the connection status and negotiation rate of the wireless communication device, the control module first determines whether the wireless communication device is currently connected to a terminal device. If the connection status indicates a terminal device is connected, the control module then determines the negotiation rate. If the current negotiation rate is greater than a preset negotiation rate, the control module outputs a first control signal to the voltage regulation module to adjust the output voltage of the power supply module to a first preset range. If the current negotiation rate is not greater than the preset negotiation rate, the control module outputs a first control signal to the voltage regulation module to adjust the output voltage of the power supply module to a second preset range. The control module dynamically adjusts the output voltage by outputting corresponding control signals based on the acquired connection status and negotiation rate of the wireless communication device.

[0015] In one optional embodiment, the voltage regulation module includes at least one voltage regulation unit, a first resistor, and a second resistor, wherein:

[0016] For each voltage regulation unit, the control terminal of the voltage regulation unit is electrically connected to the output terminal of the control module for inputting the first control signal. The first terminal of the voltage regulation unit is electrically connected to one end of the first resistor, one end of the second resistor, and the feedback terminal of the power supply module. The second terminal of the voltage regulation unit and the other end of the second resistor are both grounded.

[0017] The other end of the first resistor is electrically connected to the output terminal of the power module;

[0018] The voltage regulation unit is used to open the path between the first terminal and the second terminal of the voltage regulation unit under the control of the first control signal, so as to change the voltage division ratio of the feedback input of the power module.

[0019] In the circuit described above, the voltage regulation module includes at least one voltage regulation unit, a first resistor, and a second resistor. When all voltage regulation units are not operating, the first and second resistors form an initial voltage divider circuit to provide an initial voltage division ratio to the feedback terminal of the power supply module, ensuring the normal operation of the power supply module. When the voltage regulation unit is operating, the operating voltage regulation unit, the first resistor, and the second resistor together form a voltage divider circuit to change the voltage division ratio input to the feedback terminal of the power supply module. By combining the voltage regulation unit, the first resistor, and the second resistor, the voltage division ratio input to the feedback terminal of the power supply module is changed, thereby enabling the power supply module to adjust the output voltage according to the voltage division ratio, achieving flexible adjustment of the output voltage.

[0020] In one optional embodiment, the voltage regulation unit includes a switching transistor and a feedback resistor, wherein:

[0021] The control terminal of the switching transistor serves as the control terminal of the voltage regulation unit, the first terminal of the switching transistor serves as the first terminal of the voltage regulation unit, the second terminal of the switching transistor is electrically connected to one end of the feedback resistor, and the other end of the feedback resistor serves as the second terminal of the voltage regulation unit.

[0022] In the circuit described above, the voltage regulation unit includes a switching transistor and a feedback resistor. The switching transistor is turned on under the control of the first control signal. After the switching transistor is turned on, it forms a parallel structure with its corresponding feedback resistor and the second resistor, which changes the voltage division ratio input to the feedback terminal of the power supply module, thereby enabling the power supply module to regulate the output voltage according to the voltage division ratio.

[0023] In an optional embodiment, the control module is further configured to output a second control signal based on the connection status;

[0024] The power module is further configured to stop providing the output voltage to the FEM after receiving the second control signal.

[0025] In one optional embodiment, the control module is specifically used for:

[0026] If the connection status is determined to be no device connection, then the second control signal is output.

[0027] In the circuit described above, after the control module obtains the connection status of the wireless communication device, it first determines whether the wireless communication device is connected to a terminal device at the current moment. If the connection status shows that no terminal device is connected, the control module outputs a second control signal to the power module to control the power module to stop working and enter a low-power mode.

[0028] In one alternative embodiment, the first control signal is a pulse width modulation (PWM) signal.

[0029] The circuit described above uses a PWM signal to control the voltage regulation module. The duty cycle of the PWM signal is set according to the magnitude of the voltage change, and the voltage regulation module is controlled by the PWM signal with the preset duty cycle. This reduces the risk caused by voltage jumps during the adjustment of the output voltage, ensures the normal operation of the equipment, and improves safety.

[0030] In one optional embodiment, a temperature detection module is also included;

[0031] The temperature detection module is used to collect the operating temperature of the wireless communication device in real time;

[0032] The control module is further configured to output the first control signal based on the negotiation rate, the connection status, and the operating temperature.

[0033] The circuit described above also includes a temperature detection module, which collects the operating temperature of the wireless communication device in real time and transmits the collected operating temperature to the control module. The control module then outputs a first control signal to the voltage regulation module based on the negotiation rate, connection status, and control temperature to control the adjustment of the output voltage.

[0034] In one optional embodiment, the control module is specifically used for:

[0035] If it is determined that the connection status is that a device is connected, the negotiation rate is greater than the preset negotiation rate, and the operating temperature is lower than the preset temperature, then a first control signal is output to adjust the output voltage to a first preset range.

[0036] If it is determined that the connection status is that a device is connected, the negotiation rate is not greater than the preset negotiation rate, and the operating temperature is higher than the preset temperature, then a first control signal is output to adjust the output voltage to a second preset range.

[0037] In the above circuit, after the control module determines that a terminal device is connected, if the negotiation rate of the wireless communication device is greater than the preset negotiation rate, the wireless communication device generates relatively little heat, below the preset temperature. The control module then outputs a first control signal to adjust the output voltage to a first preset range. Conversely, if the negotiation rate of the wireless communication device is not greater than the preset negotiation rate, the wireless communication device generates significantly more heat, above the preset temperature. In this case, the control module outputs a first control signal to adjust the output voltage to a second preset range. Therefore, by adjusting the output voltage based on the current operating temperature of the wireless communication device, the power consumption of the device can be reduced, and the system performance of the device can be optimized.

[0038] In a second aspect, embodiments of the present invention provide a voltage regulation method, applied to a voltage regulation circuit as described in any embodiment of the first aspect, the method comprising:

[0042] If it is determined that the connection status is that a device is connected and the negotiation rate is greater than the preset negotiation rate, then the output voltage is adjusted to the first preset range.

[0043] If it is determined that the connection status is that a device is connected, and the negotiation rate is not greater than the preset negotiation rate, then the output voltage is adjusted to the second preset range.

[0044] In an optional embodiment, the method further includes:

[0045] Based on the connection status, stop outputting the output voltage.

[0046] In one optional embodiment, stopping the output voltage based on the connection state includes:

[0047] If the connection status is determined to be no device connection, then the output voltage is stopped.

[0048] In an optional embodiment, the method further includes:

[0049] Obtain the operating temperature of the wireless communication device;

[0050] The output voltage is adjusted based on the negotiation rate, the connection status, and the operating temperature.

[0051] In one optional embodiment, adjusting the output voltage based on the negotiation rate, the connection status, and the operating temperature includes:

[0052] If it is determined that the connection status is that a device is connected, the negotiation rate is greater than the preset negotiation rate, and the operating temperature is lower than the preset temperature, then the output voltage is adjusted to the first preset range.

[0053] If it is determined that the connection status is that a device is connected, the negotiation rate is not greater than the preset negotiation rate, and the operating temperature is higher than the preset temperature, then the output voltage is adjusted to the second preset range.

[0054] Thirdly, embodiments of the present invention provide a wireless communication device, including at least one front-end module (FEM) and a voltage regulation circuit as described in any embodiment of the first aspect.

[0055] Fourthly, embodiments of the present invention provide a voltage regulation device applied to a wireless communication device, the wireless communication device including at least one front-end module (FEM), comprising:

[0058] In one optional embodiment, the voltage regulation module is specifically used for:

[0059] If it is determined that the connection status is that a device is connected and the negotiation rate is greater than the preset negotiation rate, then the output voltage is adjusted to the first preset range.

[0060] If it is determined that the connection status is that a device is connected, and the negotiation rate is not greater than the preset negotiation rate, then the output voltage is adjusted to the second preset range.

[0061] In an optional embodiment, the voltage regulation module is further configured to:

[0062] Based on the connection status, stop outputting the output voltage.

[0063] In one optional embodiment, the voltage regulation module is specifically used for:

[0064] If the connection status is determined to be no device connection, then the output voltage is stopped.

[0065] In one optional embodiment, the device further includes a temperature detection module;

[0066] The temperature detection module is used to obtain the operating temperature of the wireless communication device;

[0067] The voltage regulation module is also used to regulate the output voltage according to the negotiation rate, the connection status, and the operating temperature.

[0082] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0083] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0084] In practical applications, according to WiFi protocols, the negotiation handshake between terminal devices and wireless communication devices involves different negotiation rates depending on the environment. For example, according to the 802.11n protocol, the negotiation rate can be 65Mbps, 72Mbps, 135Mbps, 144Mbps, 150Mbps, 270Mbps, 300Mbps, 450Mbps, or 600Mbps. A communication mode where the terminal device and wireless communication device communicate at a negotiation rate less than 200Mbps is considered a low-speed transmission mode; a communication mode where the terminal device and wireless communication device communicate at a negotiation rate of not less than 200Mbps is considered a high-speed transmission mode. The corresponding EVM (Effective Virtualization) index also differs under different transmission modes. Specifically, when the wireless communication device is in low-speed transmission mode, its EVM index is relatively low. In this case, reducing the FEM (Fuel Electron Device) supply voltage has little impact on the EVM index and can reduce power consumption and improve the device's operating temperature. When the wireless communication device is in high-speed transmission mode, its EVM index is relatively high. In this case, the FEM supply voltage should be increased to ensure the excellent system performance of the wireless communication device.

[0085] In related technologies, the FEM in a wireless communication device can be powered by a single fixed power supply. After the wireless communication device is manufactured, its power consumption in the working state is basically constant. If the power consumption of the wireless communication device is reduced, its system performance will inevitably be reduced, thereby affecting the user experience of the end user.

[0086] The FEM in wireless communication devices can also be powered by multiple switching power supplies, enabling power chips with different voltage output values ​​under different conditions. However, this method greatly increases production costs due to the excessive number of switching power supplies used, and is not conducive to the miniaturization of the device.

[0087] Based on this, embodiments of the present invention provide a voltage regulation circuit, method, apparatus, wireless communication device, and medium to achieve dynamic adjustment of the power consumption of the wireless communication device, thereby optimizing the system performance of the wireless communication device.

[0088] Example 1

[0089] This invention provides a voltage regulation circuit applied to a wireless communication device, which includes at least one front-end module (FEM), such as... Figure 1 As shown, the voltage regulation circuit includes a control module 11, a voltage regulation module 12, and a power supply module 13, wherein:

[0090] The control module 11 is used to acquire the negotiation rate and connection status of the wireless communication device, and output a first control signal based on the negotiation rate and connection status.

[0091] The voltage regulation module 12 is used to receive the first control signal and, under the control of the first control signal, regulate the output voltage VCC of the power supply module 13;

[0092] Power module 13 is used to provide the regulated output voltage VCC to FEM 14.

[0093] This invention provides a voltage regulation circuit, including a control module 11, a voltage regulation module 12, and a power supply module 13. The control module 11 acquires the negotiation rate and connection status of a wireless communication device, and outputs a first control signal based on the negotiation rate and connection status. The voltage regulation module 12 receives the first control signal and, under its control, regulates the output voltage VCC of the power supply module 13. The power supply module 13 provides the regulated output voltage VCC to the FEM 14. Because the output voltage VCC supplying power to the FEM 14 is adjusted according to the negotiation rate and connection status of the wireless communication device, dynamic processing of the power consumption of the wireless communication device is achieved, thereby optimizing the system performance of the wireless communication device and improving the user experience.

[0094] In this embodiment of the application, the negotiation rate of the wireless communication device is the transmission rate of information transmission between the terminal and the wireless communication device.

[0095] It should be noted that, in this embodiment of the invention, the control module 11 can be either an MCU (Microcontroller Unit) or a CPU (Central Processing Unit), and this embodiment of the invention does not impose any restrictions on it. Furthermore, in this embodiment of the invention, the power supply module 13 can be either an adjustable DC-DC (Direct Current-Direct Current) power supply or an adjustable LDO (Low Dropout Regulator) power supply, and this embodiment of the invention does not impose any restrictions on it.

[0096] In specific implementation, such as Figure 1 As shown, the first output terminal of the control module 11 is electrically connected to the input terminal of the voltage regulation module 12, and is used to output a first control signal to the voltage regulation module 12. The second output terminal of the control module 11 is electrically connected to the control terminal of the power supply module 13. The output terminal of the voltage regulation module 12 is electrically connected to the feedback terminal of the power supply module 13, and is used to regulate the output voltage VCC of the power supply module 13. The output terminal of the power supply module 13 is electrically connected to the power supply terminal of the FEM 14, and is used to output the output voltage VCC that supplies power to the FEM 14.

[0097] In an optional embodiment, the control module 11 is specifically used for:

[0098] If it is determined that there is a device connected and the negotiation rate is greater than the preset negotiation rate, then a first control signal is output to adjust the output voltage to the first preset range.

[0099] If the connection status is determined to be that a device is connected and the negotiation rate is not greater than the preset negotiation rate, then a first control signal is output to adjust the output voltage to the second preset range.

[0100] In specific implementation, the control module 11 acquires the current connection status and negotiation rate of the wireless communication device. After acquiring the above information, it first identifies the connection status. If the connection status indicates that a terminal device is connected, it means that the wireless communication device needs to communicate with the terminal device. At this time, it judges the negotiation rate. If the current negotiation rate is greater than the preset negotiation rate (for example, the preset negotiation rate can be 200Mbps), it means that the wireless communication device is currently working in high-speed transmission mode. Correspondingly, the EVM index of the wireless communication device is high. If the output voltage of the power module 13 is low at this time and not within the first preset range, in order to meet the EVM index, the first control signal output by the control module 11 adjusts the output voltage of the power module 13 to the first preset range to ensure the working performance of the wireless communication device. If the output voltage of the power module 13 is low at this time, it is not within the first preset range. If the current negotiation rate is high and within the first preset range, the first control signal output by the control module 11 adjusts the output voltage of the power module 13 to a lower voltage value within the first preset range to appropriately reduce the power consumption of the device. If the current negotiation rate is not greater than the preset negotiation rate, it indicates that the wireless communication device is currently operating in a low-speed transmission mode, and correspondingly, the EVM index of the wireless communication device is low. If the output voltage of the power module 13 is high and not within the second preset range, the first control signal output by the control module 11 adjusts the output voltage of the power module 13 to the second preset range. If the output voltage of the power module 13 is low and within the second preset range, the first control signal output by the control module 11 adjusts the output voltage of the power module 13 to a lower voltage value within the second preset range to reduce the power consumption of the wireless communication device and improve the working efficiency of the device.

[0101] It should be noted that, in this embodiment of the invention, the minimum value in the first preset range is greater than the maximum value in the second preset range. Specifically, the first preset range can be a set of larger values ​​among the power supply voltages that enable the FEM to work normally, and the second preset range can be a set of smaller values ​​among the power supply voltages that enable the FEM to work normally.

[0102] Optionally, in this embodiment of the invention, the power supply voltage range for FEM 14 to operate normally is 3.3V to 5.0V. Since the EVM index is high when the wireless communication device is in high-speed transmission mode, the voltage value corresponding to the first preset range should be larger. For example, the first preset range can be 4.5V to 5.0V to ensure that the output voltage VCC supplying power to FEM 14 is high, thereby ensuring the normal operation of the wireless communication device. Since the EVM index is low when the wireless communication device is in low-speed transmission mode, the voltage value corresponding to the second preset range should be smaller. For example, the second preset range can be 3.3V to 4.4V. When the output voltage VCC supplying power to FEM 14 is low, the wireless communication device can still operate normally, and the power consumption of the wireless communication device is also low, thereby achieving the goal of reducing power consumption without affecting device performance.

[0103] For example, if a terminal device is connected, and the control module identifies that the current negotiation rate is greater than the preset negotiation rate, the control module 11 outputs a first control signal, controlling the output voltage VCC of the power supply module 13 to be 4.6V, thereby achieving the goal of minimizing the power consumption of the device while ensuring its operating performance. If a terminal device is connected, and the control module identifies that the current negotiation rate is not greater than the preset negotiation rate, the control module 11 outputs a first control signal, controlling the output voltage VCC of the power supply module 13 to be 3.4V, thereby achieving the goal of reducing the power consumption of the wireless communication device while also meeting the requirements for normal operation of the device.

[0104] In an optional embodiment, the control module 11 is further configured to output a second control signal based on the connection status;

[0105] The power module 13 is also used to stop providing the output voltage VCC to the FEM 14 after receiving the second control signal.

[0106] Optionally, if the connection status is determined to be no device connected, a second control signal is output.

[0107] If the connection status is "no terminal device connected," it means that the wireless communication device does not need to communicate with the terminal device. At this time, the control module 11 outputs a second control signal to the power module 13 to disable the power module 13, that is, to stop supplying power to the FEM 14, so as to significantly reduce the power consumption of the wireless communication device. When a terminal device communicates with the wireless communication device, the control module 11 outputs an enable signal to the power module 13, thereby waking up the power module 13 so that the power module 13 supplies power to the FEM 14.

[0108] Optional, such as Figure 2As shown in the embodiment of the present invention, the voltage regulation module 12 may include voltage regulation modules 1 to n. Correspondingly, the power supply module 13 may include power supply modules 1 to n that correspond one-to-one with the voltage regulation modules 1 to n. Each power supply module supplies power to m FEMs simultaneously. For example, each power supply module can supply power to 4 FEMs simultaneously. Therefore, FEM 14 may include n FEM modules, namely (FEM11, FEM12, FEM13, FEM14) to (FEMn1, FEMn2, FEMn3, FEMn4). For example, the voltage regulation module 1 outputs a first control signal to the power supply module 1 to regulate the output voltage VCC1 of the power supply module 1. The output voltage VCC1 is used to supply power to the first FEM module (FEM11, FEM12, FEM13, FEM14).

[0109] Specifically, if the connection status obtained by the control module 11 is no terminal device connected, the control module 11 sends a second control signal to the other power modules except power module k according to a preset strategy, where 1≤k≤n. After receiving the second control signal, the other power modules go into sleep mode, that is, they stop supplying power to their corresponding FEM modules to significantly reduce the power consumption of the wireless communication device. At the same time, power module k and the FEM module connected to power module k remain in working state. If the terminal device requests to communicate with the wireless communication device, the terminal device sends a radio frequency signal to the wireless communication device. Since the function of FEM is to receive radio frequency signals, the other power modules are in sleep mode at this time, and only the FEM module connected to power module k is in working state. Therefore, the FEM module connected to power module k will receive the radio frequency signal sent by the terminal device. At this time, the control module 11 determines that a terminal device is trying to connect by the radio frequency signal received by the working FEM module. The control module 11 sends an enable signal to the other power modules except power module k to activate the power modules in sleep mode, so that the wireless communication device can work normally.

[0110] For example, if the connection status obtained by the control module 11 is no terminal device connected, the control module 11 sends a second control signal to the power modules 2 to n to make the power modules 2 to n go into sleep mode. Since only the power module 1 is in normal working state at this time, the power consumption of the wireless communication device is greatly reduced.

[0111] In this application embodiment, the power module k can be any power module, and this application embodiment does not limit it.

[0112] It should be noted that, in this embodiment of the invention, the control module 11 can identify the current negotiation rate of the wireless communication device by recognizing the data transmission mode flag bit.

[0113] In the circuit described above, after acquiring the connection status and negotiation rate of the wireless communication device, the control module first determines whether the wireless communication device is currently connected to a terminal device. If the connection status indicates no terminal device is connected, the control module 11 outputs a second control signal to the power module 13 to control the power module 13 to stop working and enter a low-power mode. If the connection status indicates a terminal device is connected, the control module 11 then determines the negotiation rate. If the current negotiation rate is greater than a preset negotiation rate, the control module 11 outputs a first control signal to the voltage regulation module 12 to control the voltage regulation module 12 to adjust the output voltage VCC of the power module 13 to a first preset range. If the current negotiation rate is not greater than the preset negotiation rate, the control module 11 outputs a first control signal to the voltage regulation module 12 to control the voltage regulation module 12 to adjust the output voltage VCC of the power module 13 to a second preset range. The control module 11 outputs corresponding control signals based on the acquired connection status and negotiation rate of the wireless communication device to achieve dynamic adjustment of the output voltage VCC.

[0114] In one alternative embodiment, such as Figure 3 As shown, the voltage regulation module 12 includes at least one voltage regulation unit 121, a first resistor R1, and a second resistor R2, wherein:

[0115] For each voltage regulation unit 121, the control terminal of the voltage regulation unit 121 is electrically connected to the output terminal of the control module 11 for inputting the first control signal. The first terminal of the voltage regulation unit 121 is electrically connected to one end of the first resistor R1, one end of the second resistor R2 and the feedback terminal of the power module 13 respectively. The second terminal of the voltage regulation unit 121 and the other end of the second resistor R2 are both grounded.

[0116] The other end of the first resistor R1 is electrically connected to the output terminal of the power module 13;

[0117] The voltage regulation unit 121 is used to conduct the path between the first terminal and the second terminal of the voltage regulation unit 121 under the control of the first control signal, so as to change the voltage division ratio of the feedback terminal input of the power module 13.

[0118] In specific implementation, initially, all voltage regulation units 121 are in the off state. The first resistor R1 and the second resistor R2 form an initial voltage divider circuit, providing an initial voltage division ratio of R1 / R2 to the feedback terminal of the power module 13, thereby ensuring the normal operation of the power module 13. For example, the output voltage VCC of the power module 13 at the initial moment can be:

[0119]

[0120] Where R1 is the resistance value of the first resistor R1, R2 is the resistance value of the second resistor R2, and Vr is a preset reference value, for example, Vr can be 0.6V.

[0121] It should be noted that, in this embodiment of the invention, the output voltage VCC of the power module 13 at the initial moment can be set to 3.3V, 5.0V, or any voltage value between 3.3V and 5.0V. This embodiment of the invention does not impose any restrictions on this.

[0122] The following embodiment is illustrated with the power module 13's output voltage VCC being 3.3V at the initial moment:

[0123] In a specific implementation, when the wireless communication device communicates with the terminal device, the control module 11 sends a first control signal to the control terminal of multiple parallel-connected voltage regulation units 121 according to the current negotiation rate, so as to control the conduction of the path between the first terminal and the second terminal of the corresponding voltage regulation unit 121, thereby changing the voltage division ratio of the feedback terminal input of the power module 13.

[0124] Optionally, the first control signal can be a high or low level control signal or a PWM signal.

[0125] In practical implementation, a PWM signal is used to control the voltage regulation module. The duty cycle of the PWM signal is set according to the magnitude of the voltage change, and the voltage regulation module is controlled by the PWM signal with the preset duty cycle to achieve smooth switching of the output voltage, reduce the risk caused by voltage jumps during the adjustment of the output voltage, ensure the normal operation of the equipment, and improve safety.

[0126] In the circuit described above, the voltage regulation module 12 includes at least one voltage regulation unit 121, a first resistor R1, and a second resistor R2. When all voltage regulation units 121 are not working, the first resistor R1 and the second resistor R2 form an initial voltage divider circuit to provide an initial voltage division ratio to the feedback terminal of the power supply module 13, ensuring the normal operation of the power supply module 13. When the voltage regulation unit 121 is working, the working voltage regulation unit 121, the first resistor R1, and the second resistor R2 together form a voltage divider circuit to change the voltage division ratio input to the feedback terminal of the power supply module 13. By combining the voltage regulation unit 121, the first resistor R1, and the second resistor R2, the voltage division ratio input to the feedback terminal of the power supply module 13 is changed, thereby enabling the power supply module 13 to adjust the output voltage VCC according to the voltage division ratio, achieving flexible adjustment of the output voltage VCC.

[0127] In one alternative embodiment, such as Figure 3As shown, the voltage regulation unit 121 includes switching transistors (M11, M12, ..., M1n) and feedback resistors (R11, R12, ..., R1n), wherein:

[0128] The control terminals of the switching transistors (M11, M12, ..., M1n) serve as the control terminals of the voltage regulation unit 121. The first terminal of the switching transistors (M11, M12, ..., M1n) serves as the first terminal of the voltage regulation unit 121. The second terminal of the switching transistors (M11, M12, ..., M1n) is electrically connected to one end of the feedback resistors (R11, R12, ..., R1n). The other end of the feedback resistors (R11, R12, ..., R1n) serves as the second terminal of the voltage regulation unit 121.

[0129] Optionally, the switching transistors (M11, M12, ..., M1n) can be NPN transistors, and the first resistor R1, the second resistor R2, and the feedback resistors (R11, R12, ..., R1n) are all adjustable resistors.

[0130] For example, when the wireless communication device communicates with the terminal device, if the control module 11 determines that the current negotiation rate is greater than the preset negotiation rate, it indicates that the wireless communication device is operating in high-speed transmission mode. Correspondingly, the wireless communication device operating in high-speed transmission mode has a higher EVM index. At this time, the FEM operating voltage should be set to a higher voltage value to meet the EVM index. Specifically, the first control signal output by the control module 11 controls the first voltage adjustment unit 121 and the second voltage adjustment unit 121 to conduct. Then, the voltage division ratio input to the feedback terminal of the power supply module 13 is: R1 / (R2 / / R11 / / R12). At this time, the output voltage VCC of the power supply module 13 is:

[0131]

[0132] Wherein, R1 is the resistance value of the first resistor R1, R2 is the resistance value of the second resistor R2, R11 is the resistance value of the feedback resistor R11 in the first voltage regulation unit 121, R12 is the resistance value of the feedback resistor R12 in the second voltage regulation unit 121, and Vr is the preset reference value.

[0133] By controlling the conduction of the corresponding voltage regulation unit 121, the output voltage can be increased in high-speed transmission mode to optimize system performance.

[0134] For example, when the negotiation rate between the wireless communication device and the terminal device is not greater than the preset negotiation rate, it indicates that the wireless communication device is operating in a low-speed transmission mode. Correspondingly, the EVM (Electronic Power Regulator) of a wireless communication device operating in low-speed transmission mode is lower. In this case, the FEM (Fuel Regulator) operating voltage should be set to a lower value to reduce the power consumption of the wireless communication device. Specifically, the first control signal output by the control module 11 controls the reduction of the voltage division ratio input to the feedback terminal of the power module 13. For example, if the first control signal controls the third voltage regulation unit 121 to turn on, then the voltage division ratio input to the feedback terminal of the power module 13 is: R1 / (R2 / / R13). At this time, the output voltage VCC of the power module 13 is:

[0135]

[0136] Wherein, R1 is the resistance value of the first resistor R1, R2 is the resistance value of the second resistor R2, R13 is the resistance value of the feedback resistor R13 in the third voltage regulation unit 121, and Vr is the preset reference value.

[0137] By controlling the conduction of the corresponding voltage regulation unit 121, the output voltage can be reduced in low-speed transmission mode to reduce the power consumption of wireless communication devices and improve working efficiency.

[0138] Furthermore, since the voltage regulation module 12 in this voltage regulation circuit is composed of a low-cost switching transistor and an adjustable resistor, compared with the method of setting multiple switching power supplies in related technologies, this circuit can not only reduce production costs, but also facilitate the miniaturization of wireless communication devices.

[0139] In the circuit described above, the voltage regulation unit 121 includes switching transistors (M11, M12, ..., M1n) and feedback resistors (R11, R12, ..., R1n). The switching transistors (M11, M12, ..., M1n) are turned on under the control of the first control signal. After the switching transistors (M11, M12, ..., M1n) are turned on, their corresponding feedback resistors (R11, R12, ..., R1n) and the second resistor R2 form a parallel structure, which changes the voltage division ratio input to the feedback terminal of the power supply module 13, thereby causing the power supply module 13 to adjust the output voltage VCC according to the voltage division ratio.

[0140] In one alternative embodiment, such as Figure 4 As shown, the voltage regulation circuit also includes a temperature detection module 41;

[0141] Temperature detection module 41 is used to collect the operating temperature of wireless communication equipment in real time;

[0142] The control module 11 is also used to output a first control signal based on the negotiation rate, connection status and operating temperature.

[0143] It should be noted that in this embodiment of the invention, the temperature detection module 41 can be a temperature sensor, a thermistor, or a temperature acquisition unit integrated inside the control module 11. This embodiment of the invention does not impose any restrictions on this.

[0144] The circuit described above also includes a temperature detection module 41, which collects the operating temperature of the wireless communication device in real time and transmits the collected operating temperature to the control module 11. The control module 11 then outputs a first control signal to the voltage regulation module 12 based on the negotiation rate, connection status, and control temperature to control the adjustment of the output voltage VCC.

[0145] In an optional embodiment, the control module 11 is specifically used for:

[0146] If the connection status is determined to be that a device is connected, the negotiation rate is greater than the preset negotiation rate, and the operating temperature is lower than the preset temperature, then a first control signal is output to adjust the output voltage to the first preset range.

[0147] If the connection status is determined to be that a device is connected, the negotiation rate is greater than the preset negotiation rate, and the operating temperature is higher than the preset temperature, then the output voltage will not be adjusted, or it will be adjusted step by step according to the preset range.

[0148] If the connection status is determined to be that a device is connected, the negotiation rate is not greater than the preset negotiation rate, and the operating temperature is higher than the preset temperature, then a first control signal is output to adjust the output voltage to the second preset range.

[0149] If the connection status is confirmed to be that a device is connected, the negotiation rate is not greater than the preset negotiation rate, and the operating temperature is lower than the preset temperature, then the output voltage will not be adjusted, or it will be adjusted step by step according to the preset range.

[0150] In practical implementation, when the terminal device communicates with the wireless communication device over a long distance, the wireless terminal device operates in a low-speed transmission mode, and its negotiation rate is no greater than the preset negotiation rate. At this time, the wireless communication device generates more heat, but its EVM index is low, so a lower supply voltage can be used to power the FEM to reduce the device's power consumption. When the terminal device communicates with the wireless communication device over a short distance, the wireless terminal device operates in a high-speed transmission mode, and its negotiation rate is greater than the preset negotiation rate. At this time, the wireless communication device generates less heat, but its EVM index is high, so a higher supply voltage is required to power the FEM to ensure the device's operating performance.

[0151] Specifically, the temperature detection module 41 transmits the current operating temperature of the wireless communication device to the control module 11. If the control module 11 determines that a terminal device is communicating with the wireless communication device, and if the current negotiation rate is greater than a preset negotiation rate and the current operating temperature of the wireless communication device is lower than a preset temperature (e.g., 35°C), the output voltage VCC can be appropriately increased, but not higher than a first preset range. For example, the output voltage VCC can be adjusted from 4.0V to 4.6V to ensure the performance of the wireless communication device. If the current operating temperature of the wireless communication device is higher than the preset temperature, in one possible implementation, the output voltage VCC can be gradually decreased according to a preset range, but not lower than the first preset range. For example, the preset range can be 0.2V. For instance, the output voltage VCC can be adjusted from 5.0V to 4.8V, and then to 4.6V, to appropriately reduce the device's power consumption while ensuring the operating performance of the wireless communication device. In another possible implementation, the output voltage VCC can remain unchanged to ensure the superior performance of the wireless communication device.

[0152] If it is determined that the current negotiation rate is not greater than the preset negotiation rate, and the current operating temperature of the wireless communication device is higher than the preset temperature (e.g., the preset temperature could be 35°C), the output voltage VCC can be gradually reduced by a preset increment, but it cannot fall below a second preset range (e.g., the preset increment could be 0.2V). For example, the output voltage VCC can be adjusted from 4.0V to 3.8V, and then to 3.6V, to reduce the power consumption of the wireless communication device and improve its operating efficiency. If the current operating temperature of the wireless communication device is lower than the preset temperature, in one possible implementation, the output voltage VCC can be gradually reduced by a preset increment, but it cannot fall below a second preset range (e.g., the output voltage VCC can be adjusted from 3.6V to 3.4V), to appropriately reduce the power consumption of the wireless communication device. In another possible implementation, the output voltage VCC can remain unchanged to ensure the superior performance of the wireless communication device.

[0153] In the circuit described above, after determining that a terminal device is connected, if the negotiation rate of the wireless communication device is greater than a preset negotiation rate, the wireless communication device generates relatively little heat, below a preset temperature. The control module then outputs a first control signal to adjust the output voltage to a first preset range. Conversely, if the negotiation rate of the wireless communication device is not greater than the preset negotiation rate, the wireless communication device generates significantly more heat, above a preset temperature. In this case, the control module outputs the first control signal to adjust the output voltage to a second preset range. Therefore, by adjusting the output voltage based on the current operating temperature of the wireless communication device, the power consumption of the device can be reduced, and the system performance of the device can be optimized.

[0154] Optionally, since the power module 13 can simultaneously power a preset number of FEMs 14, for example, the preset number can be 4, therefore, as Figure 5 As shown, a preset number of FEMs 14 can be integrated into a single RF chip 51. This approach facilitates the miniaturization of wireless communication devices, meeting the design requirements of subsequent WIFI6E and even WIFI7.
