[0002] At present, in order to save power consumption, it is very common to use AVS (Adaptive Voltage Scaling) voltage regulation modules in electronic devices such as mobile phones and tablets to adjust the output voltage of PMIC (Power Management Integrated Circuit) modules according to the load severity.

[0003] In related technologies, in order to take into account various conditions such as consistency and reliability, the AVS voltage regulation module is generally solidified inside the SoC (System on Chip) chip, and a step-by-step slow voltage regulation solution is adopted.

[0004] However, the application environment of current electronic devices is becoming more and more complex. Relying solely on the AVS voltage regulation mechanism within the SoC chip can no longer take into account stability issues caused by some rapid anomalies such as external interference. For example, external interference may cause the voltage of the functional module of the electronic device to drop. If it drops below the lower voltage limit that the functional module can accept, the functional module will work abnormally and stability issues will occur. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0016] At present, the traditional AVS voltage regulation scheme of step-by-step slow voltage regulation can no longer take into account the impact of some rapid abnormalities such as external interference, and cannot solve the stability problem caused by voltage drop of functional modules. Figure 1In the related art, the AVS voltage regulation system in the electronic device may include a SoC chip and a PMIC module, the SoC chip includes a central processing unit, a memory, an arbitrator, an AVS sensor and an AVS controller, and the PMIC module includes a voltage regulation unit. The voltage regulation scheme based on the AVS voltage regulation system includes: the central processing unit reads the initial voltage value pre-stored in the memory and gives the initial voltage value to the arbitrator; the arbitrator can send a voltage regulation command to the PMIC module through the SPMI (Serial Peripheral Management Interface) bus, and the voltage regulation command includes a power supply power-on instruction and an initial voltage value; the PMIC module outputs the power supply voltage VDD to the SoC chip according to the voltage regulation command; the AVS sensor on the SoC chip detects the current power supply voltage VDD, as well as sensor data such as the load and temperature in the current SoC chip and outputs them to the AVS controller; the AVS controller comprehensively determines a more appropriate voltage value based on the value of the current power supply voltage VDD and the sensor data such as the load and temperature in the current SoC chip, and then outputs it to the arbitrator to update the voltage value; the arbitrator sends a voltage regulation command to the PMIC module again through the SPMI bus, and the voltage regulation command includes updated voltage value information; the voltage regulation unit in the PMIC module adjusts the power supply voltage VDD currently output by the PMIC module according to the updated voltage value information, and then can adjust the voltage multiple times until the power supply voltage VDD output by the PMIC module reaches the expected voltage value.

[0017] In actual applications, external interferences such as radio frequency interference, audio PA (Power Amplifier) ​​interference, PMIC noise interference, etc. may cause the voltage of the functional module to drop. If the voltage drops below the lower limit that the functional module can accept, the functional module will work abnormally and stability problems may occur. The traditional AVS solution that slowly adjusts the voltage step by step cannot solve the stability problems caused by the voltage drop caused by these external interferences.

[0018] Based on this, the embodiment of the present application can generate a boost command when a control command instructing the target power amplifier module to work is detected, and increase the output voltage provided to the second target module by the PMIC module based on the boost command. Since the output voltage provided by the PMIC module to the second target module is increased, the anti-interference capability of the second target module can be improved, avoiding stability problems caused by interference from the target power amplifier module to the second target module, thereby improving the system stability of the electronic device.

[0019] The voltage adjustment method, voltage regulation module and electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0020] like Figure 2As shown, the embodiment of the present application provides a voltage adjustment method, which may include: Step 210: Obtaining a control command from the first target module to the target power amplifier module; Step 220: generating a voltage boost command when the control command instructs the target power amplification module to operate; Step 230: Based on the boost command, increase the output voltage provided to the second target module by the PMIC module; The first target module includes a module for controlling the operation of the target power amplification module, the second target module includes a module interfered by the target power amplification module, and the first target module is different from the second target module.

[0021] In the embodiment of the present application, the present application does not limit the specific types of the first target module and the target power amplifier module.

[0022] For example, the first target module may include a radio frequency communication module, and the target power amplifier module may be a radio frequency PA module corresponding to the radio frequency communication module. The radio frequency PA module may include but is not limited to at least one of a 5G power amplifier, a 4G power amplifier, a 3G power amplifier, and a 2G power amplifier, and the radio frequency communication module may send a control command to the radio frequency PA module to control the operation of the radio frequency PA module.

[0023] For another example, the first target module may include a short-range wireless communication module, which may include but is not limited to at least one of a WIFI module, a Bluetooth module, and an NFC (Near Field Communication) module, and the target power amplifier module may be a WCN (Wireless Communication Network) PA module. The WIFI module, the Bluetooth module, or the NFC module may send a control command to the WCN PA module to control the operation of the WCN PA module.

[0024] For another example, the first target module may include a satellite navigation and positioning module, which may include but is not limited to at least one of a GPS module and a Beidou module, and the target power amplifier module may be a satellite navigation and positioning PA module corresponding to the satellite navigation and positioning module. The GPS module or the Beidou module may send a control command to the corresponding satellite navigation and positioning PA module to control the operation of the corresponding satellite navigation and positioning PA module.

[0025] For another example, the first target module may include an audio processing module, and the target power amplification module may be an audio PA module corresponding to the audio processing module. The audio processing module may send a control command to the corresponding audio PA module to control the operation of the corresponding audio PA module.

[0026] In the embodiment of the present application, when the control command indicates that the target power amplifier module is working, it means that the target power amplifier module is going to work next, and the target power amplifier module may interfere with the second target module when in working state. At this time, a boost command is generated based on the control command trigger, and the boost command is used to increase the working voltage of the second target module, so as to improve the anti-interference ability of the second target module and avoid the stability problem caused by the interference of the target power amplifier module to the second target module.

[0027] The second target module may include a module interfered by the target power amplifier module, and the first target module is different from the second target module. In practical applications, the second target module has a higher operating rate and a lower operating voltage and is easily interfered with. For example, the second target module may include but is not limited to at least one of a memory module (DDR) and a camera module (CCM).

[0028] In an embodiment of the present application, when a control command instructing the target power amplifier module to operate is detected, a boost command is generated, and the output voltage provided to the second target module through the PMIC module is increased based on the boost command, which is equivalent to increasing the supply voltage of the second target module, further improving the anti-interference capability of the second target module, avoiding stability problems caused by interference from the target power amplifier module to the second target module, and improving the system stability of the electronic device.

[0029] It can be understood that since the power supply voltage of the second target module is increased, the anti-interference ability of the second target module is stronger. Even if the second target module is interfered by the target power amplifier module and causes the voltage to drop, the power supply voltage of the second target module will not drop below the preset lower limit value. The power supply voltage of the second target module is always maintained above the preset lower limit value, which can ensure the normal operation of the second target module and avoid stability problems.

[0030] According to the voltage adjustment method provided by the embodiment of the present application, a control command of the first target module to the target power amplifier module is obtained; when the control command indicates that the target power amplifier module is working, a boost command is generated; based on the boost command, the output voltage provided to the second target module by the power management integrated circuit PMIC module is increased; wherein the first target module includes a module that controls the operation of the target power amplifier module, the second target module includes a module interfered by the target power amplifier module, and the first target module is different from the second target module. In this way, the present application generates a boost command when a control command indicating that the target power amplifier module is working is detected, and the output voltage provided to the second target module by the PMIC module is increased based on the boost command. Since the output voltage provided by the PMIC module to the second target module is increased, the anti-interference ability of the second target module can be improved, the stability problem caused by the interference of the target power amplifier module to the second target module is avoided, and the system stability of the electronic device is improved.

[0031] In practical applications, in order to improve the accuracy of the boost command, the embodiments of the present application can generate a boost command based on application scenario information of the electronic device, and further improve the accuracy of the boost command in combination with the application scenario information.

[0032] For example, in a specific embodiment, Figure 3 As shown, the voltage adjustment method provided in the embodiment of the present application may include: Step 310: Obtaining a control command from the first target module to the target power amplifier module; Step 320: When the control command instructs the target power amplification module to operate, obtaining at least one sensor data of the electronic device; Step 330: Determine target scene information of the electronic device based on at least one sensor data of the electronic device; Step 340: Generate a boost command based on the target scene information; Step 350: Based on the boost command, increase the output voltage provided to the second target module by the PMIC module; The first target module includes a module for controlling the operation of the target power amplification module, the second target module includes a module interfered by the target power amplification module, and the first target module is different from the second target module.

[0033] Among them, step 310 may refer to the specific content of step 210.

[0034] Among them, steps 320 to 340 may be sub-steps of step 220 .

[0035] Among them, step 350 can refer to the specific content of step 230.

[0036] In an embodiment of the present application, the present application can also obtain at least one sensor data of the electronic device, and the sensor may include but is not limited to: a light sensor, a distance sensor, a gravity sensor, an acceleration sensor, a fingerprint sensor, a gyroscope sensor, a magnetic field sensor, an air pressure sensor, a temperature sensor, a humidity sensor, a pressure sensor, a heart rate sensor, an optical sensor and an infrared sensor, etc. The present application does not limit the specific type of the sensor.

[0037] In an embodiment of the present application, target scene information of the electronic device can be determined based on at least one sensor data of the electronic device, and the target scene information is the current application scene of the electronic device. The target scene information can be determined from a variety of preset scene information. For example, based on the mapping relationship between the sensor data and the preset scene information, and at least one sensor data of the electronic device obtained, the target scene information is determined from the preset scene information.

[0038] Different target scene information generates different boost commands. For example, the boost command may include the identifier of the second target module and the boost amplitude; different target scene information generates different second target modules for the boost command, or different target scene information generates different boost amplitudes in the boost command.

[0039] For example, if it is determined based on the acceleration sensor data of the electronic device that the user is holding the electronic device and moving downward, the target scene information is determined to be an elevator scene. In the elevator scene, the RF communication module can generally automatically send a control signal to the RF PA to control the RF PA to increase the power and increase the RF signal strength, indicating that the RF PA has a stronger interference to the second target module at this time, and a boost command with a larger boost amplitude can be generated to ensure that the second target module can still work normally under stronger interference.

[0040] In this way, the present application can also determine the target scene information of the electronic device based on at least one sensor data of the electronic device, and generate a boost command based on the target scene information, thereby further improving the accuracy of the boost command.

[0041] In practical applications, the PMIC noise may also interfere with the second target module. Since the PMIC module will have MHz-level noise when the operating power is high, its interference is usually relatively large and easily interferes with the second target module. Based on this, the embodiment of the present application can also monitor the working mode of the PMIC module, generate a boost command based on the working mode of the PMIC module, and further improve the accuracy of the boost command.

[0042] For example, in another specific embodiment, Figure 4 As shown, the voltage adjustment method provided in the embodiment of the present application may include: Step 410: Obtaining a control command from the first target module to the target power amplifier module; Step 420: When the control command instructs the target power amplifier module to operate, obtain the operating mode of the PMIC module; Step 430: Generate a boost command based on the operating mode of the PMIC module; Step 440: Based on the boost command, increase the output voltage provided to the second target module by the PMIC module; The first target module includes a module for controlling the operation of the target power amplification module, the second target module includes a module interfered by the target power amplification module, and the first target module is different from the second target module.

[0043] Among them, step 410 may refer to the specific content of step 210.

[0044] Among them, steps 420 to 430 may be sub-steps of step 220 .

[0045] Among them, step 440 can refer to the specific content of step 230.

[0046] In an embodiment of the present application, the present application can also obtain the working mode of the PMIC module.

[0047] Among them, the working modes of the PMIC module can include NPM (Normal Power Mode) and LPM (Low Power Mode). In NPM mode, the PMIC module has a fast response speed and a strong load capacity, that is, after the boost command is given to the PMIC module, the PMIC can quickly raise the voltage. In LPM mode, the PMIC module has a slow response speed and a weak load capacity, that is, after the boost command is given to the PMIC module, the PMIC module raises the voltage slowly.

[0048] The working modes of the PMIC module can also include PWM (Pulse Width Modulation) mode and PFM (Pulse Frequency Modulation) mode. In PWM mode, the PMIC module keeps the output frequency constant by adjusting the pulse width, which is suitable for heavy loads; in PFM mode, the PMIC module changes the output by adjusting the pulse frequency, which is suitable for light loads.

[0049] In the embodiment of the present application, when the working mode of the PMIC module is the NPM mode or the PWM mode, the working power of the PMIC module is relatively large, so its interference is usually relatively large, and it is easy to interfere with the second target module. When the working mode of the PMIC module is the LPM mode or the PFM mode, its interference is usually relatively small.

[0050] Based on this, in the embodiment of the present application, the boost command includes a boost amplitude. The above-mentioned generating the boost command based on the working mode of the PMIC module specifically includes: When the working mode of the PMIC module is the NPM mode, generating a first boost command; When the working mode of the PMIC module is the LPM mode, generating a second boost command; The voltage boost amplitude in the first voltage boost command is greater than the voltage boost amplitude in the second voltage boost command.

[0051] Alternatively, the generating of the boost command based on the working mode of the PMIC module specifically includes: When the working mode of the PMIC module is the PWM mode, generating a third boost command; When the working mode of the PMIC module is the PFM mode, generating a fourth boost command; The voltage boost amplitude in the third voltage boost command is greater than the voltage boost amplitude in the fourth voltage boost command.

[0052] It can be understood that the greater the interference of the current working mode of the PMIC module on the second target module, the greater the boost amplitude in the generated boost command can be. In this way, the boost amplitude can be determined by considering the interference degree of the current working mode of the PMIC module on the second target module, thereby further improving the accuracy of the boost amplitude.

[0053] In practical applications, the second target module is susceptible to external interference. The embodiment of the present application can detect the working status, scene information and working mode of the target power amplifier module, and notify the PMIC module in advance to increase the power supply voltage output to the second target module before the first target module commands the target power amplifier module to work, thereby avoiding stability problems caused by external interference to the second target module and improving the system stability of the electronic device.

[0054] For example, in the voltage adjustment method provided in the embodiment of the present application, in the above step 220, generating a boost command may specifically include: acquiring at least one type of sensor data; Obtaining the operating mode of the PMIC module; A boost command is generated based on the at least one sensor data and an operating mode of the PMIC module.

[0055] The embodiment of the present application can first determine the target scene information based on at least one sensor data, and then determine the boost command based on the target scene information and the working mode of the PMIC module. The boost command includes a boost amplitude, which can be determined by the target scene information and the working mode of the PMIC module.

[0056] In addition, in practical applications, the voltage boost amplitude may also be associated with the number of target power amplification modules. For example, the greater the number of target power amplification modules, the greater the voltage boost amplitude.

[0057] In this way, the present application can monitor the working state of the target power amplifier module, the working mode of the PMIC module and the user scenario, and when a control command instructing the target power amplifier module to work is monitored, determine a boost command based on the target scenario information and the working mode of the PMIC module, and increase the output voltage provided to the second target module by the PMIC module based on the boost command. Since the output voltage provided by the PMIC module to the second target module is increased, the anti-interference ability of the second target module can be improved, the stability problem of the second target module caused by external interference is avoided, and the system stability of the electronic device is improved.

[0058] In practical applications, in order to further optimize the AVS voltage regulation scheme in related technologies and improve the system's anti-interference ability, such as Figure 5 As shown, the voltage adjustment method provided in the embodiment of the present application may include: Step 510: reading an initial voltage value pre-stored in the memory, and generating a voltage adjustment command based on the initial voltage value; Among them, each SoC chip completes the FT (Final Test) test before leaving the factory to ensure that the SoC chip functions normally. During the FT test, the CPU, GPU, DDR and other functional modules inside each SoC chip can be tested for their respective suitable operating voltage values, and the voltage values ​​can be recorded and stored in the memory. Based on this, after the electronic device is turned on, the voltage value corresponding to the operating frequency can be obtained from the memory.

[0059] Specifically, the central processing unit reads the initial voltage value pre-stored in the memory and gives the initial voltage value to the arbitrator; the arbitrator does not process the initial value obtained from the memory in the first round, and then directly sends the initial voltage value to the PMIC module through the SPMI bus to ensure that the system is quickly initialized and enters the working state.

[0060] Step 520: Send a voltage adjustment command to the PMIC module output voltage via the SPMI bus; Among them, the voltage adjustment command can be obtained by the arbitrator through comprehensive consideration. For example, if it is the first round of voltage adjustment, the voltage adjustment command can be directly generated based on the voltage value obtained from the memory, and sent to the PMIC module through the SPMI bus. The PMIC module outputs the voltage to the SoC chip based on the voltage value to ensure that the system is quickly initialized and enters the working state.

[0061] For example, the arbitrator converts the initial value obtained from the memory into a voltage adjustment command in the SPMI protocol format, and sends the voltage adjustment command to the PMIC module through the SPMI bus. The voltage adjustment command includes power-on and voltage value, and the PMIC module outputs voltage to the SoC chip based on the voltage value. For example, when the GPU module starts working, the central processing unit (CPU) obtains a voltage value of 0.8V from the memory, and the arbitrator converts it into a power-on command and a set 0.8V command. Based on the command, the PMIC module outputs 0.8V voltage to the GPU module in the SoC chip.

[0062] Step 530: The AVS sensor detects the current voltage value, as well as the load and temperature of each module in the current SoC chip, and sends them to the AVS controller.

[0063] For example, taking the GPU module in the SoC chip as an example, the actual operating voltage required by the GPU module is different under different conditions such as load weight and temperature. The heavier the load and the lower the temperature, the higher the required operating voltage, and the lighter the load and the higher the temperature, the lower the required operating voltage. Therefore, the AVS sensor can collect the real-time status of these factors and send them to the AVS controller for processing.

[0064] Step 540: The AVS controller determines the updated voltage value and sends it to the arbitrator to update the voltage value; Among them, the AVS controller can determine the updated voltage value based on the current voltage value detected by the AVS sensor, as well as the load, temperature, etc. of each module in the current SoC chip, and generate a voltage adjustment command based on the updated voltage value. The voltage adjustment command includes an updated voltage value, which is sent to the PMIC module through the SPMI bus. The PMIC module re-outputs the updated voltage value to the SoC chip to achieve adaptive voltage regulation.

[0065] For example, after the AVS sensor on the SoC chip detects the current power supply voltage VDD, as well as the sensor data such as the load and temperature in the current SoC chip and outputs them to the AVS controller, the AVS controller comprehensively determines a more appropriate voltage value based on the value of the current power supply voltage VDD and the sensor data such as the load and temperature in the current SoC chip, and then outputs it to the arbitrator to update the voltage value. Subsequently, the arbitrator sends a voltage adjustment command to the PMIC module again through the SPMI bus, and the voltage adjustment command includes the updated voltage value information; the voltage adjustment unit in the PMIC module adjusts the power supply voltage VDD currently output by the PMIC module according to the updated voltage value information.

[0066] Step 550: Obtaining a control instruction from the first target module to the target power amplifier module; Among them, step 550 can be executed by the central processing unit in the SoC chip, and can also be executed by a control chip outside the SoC chip, and the control chip is connected to the target control line, and the target control line is the control line between the first target module and the target power amplifier module.

[0067] For example, the central processor in the SoC chip can monitor the control commands of the RF communication module, WiFi module / Bluetooth module / GPS module, Beidou module, audio processing module and other modules to the target power amplifier module (various PAs) through the software path.

[0068] For another example, the input end of the control chip is connected to the RF communication module, WiFi module / Bluetooth module / GPS module, Beidou module, audio processing module and other modules, and the control chip can directly obtain the control commands of the RF communication module, WiFi module / Bluetooth module / GPS module, Beidou module, audio processing module and other modules to the target power amplifier module (various PAs).

[0069] Step 560: generating a voltage boost command when the control command indicates that the target power amplifier module is working; Among them, step 560 can be executed by the central processing unit in the SoC chip, and can also be executed by a control chip outside the SoC chip.

[0070] For example, when determining that the control command instructs the target power amplifier module to operate, the central processor in the SoC chip generates a boost command, which is used to increase the power supply voltage of the second target module.

[0071] For another example, when the control chip determines that the control command instructs the target power amplifier module to operate, the control chip compares the control command with the lookup table in the control chip to generate a boost command, which is used to increase the supply voltage of the second target module.

[0072] Step 570: Based on the boost command, increase the output voltage provided to the second target module by the PMIC module.

[0073] Among them, step 570 can be executed by the central processing unit in the SoC chip, and can also be executed by a control chip outside the SoC chip.

[0074] For example, the central processor in the SoC chip sends a boost command to the PMIC module through the arbitrator and the SPMI bus. Based on the boost command, the PMIC module controls the voltage output port BUCK connected to the second target module (such as DDR, CCM and other modules that are easily interfered with), increases the power supply voltage of the second target module, and improves the anti-interference ability of the second target module, thereby improving the system stability.

[0075] For another example, after the control chip detects the corresponding scenario, it outputs a boost command to the PMIC module through the SPMI bus. Based on the boost command, the PMIC module controls the voltage output port BUCK connected to the second target module (such as DDR, CCM and other easily interfered modules), increases the supply voltage of the second target module, and improves the anti-interference ability of the second target module, thereby improving the system stability.

[0076] Among them, step 510 to step 540 are AVS voltage adjustment steps. Step 550 to step 570 are voltage adjustment steps provided by the present application, which can improve the anti-interference ability of the module susceptible to interference.

[0077] In this way, the present application can determine the boost command when monitoring the control command instructing the target power amplifier module to work, and increase the output voltage provided by the PMIC module to the interference-susceptible module based on the boost command. Since the output voltage provided by the PMIC module to the second target module is increased, the anti-interference ability of the second target module can be improved, and the stability problems caused by external interference of the second target module are avoided, the system stability of the electronic device is improved, and the AVS voltage regulation mechanism is improved.

[0078] In practical applications, the voltage adjustment method can be executed by any control module in the electronic device. For example, the voltage adjustment method can be executed by a central processing unit (CPU) inside a SoC chip, or by a microcontroller (MCU), or by a microprocessor (MPU), etc. The present application does not impose any specific restrictions on the execution subject of the voltage adjustment method.

[0079] It should be pointed out that the CPU monitors the control commands of the RF communication module, WiFi module / Bluetooth module / GPS module, Beidou module, audio processing module and other modules to the PA through the software channel, and then controls the arbitrator to control the voltage regulation of the PMIC module through the SPMI bus. This method has disadvantages: First, some first target modules may not have software access to the central processor, so this method is difficult to implement; Second, the software path is limited by software processing time, task priority, path data transmission delay, etc., and the whole process takes a long time.

[0080] Third, the central processing unit needs to be involved every time, which consumes a lot of power.

[0081] In order to reduce this delay, a hardware identification channel (such as a control chip) can be added to monitor the working commands sent by the SoC chip to the PA to instruct the PA to work, and control the PMIC module to increase the power supply voltage output to the module that is easily interfered with.

[0082] For example, in a specific embodiment, in order to speed up the voltage regulation speed, the voltage regulation method can be executed by a control chip, and the control chip is connected to a target control line, which is a control line between the first target module and the target power amplifier module.

[0083] In this way, the control chip can directly obtain the control command of the first target module to the target power amplifier module from the target control line, detect the working status of the target power amplifier module through the hardware identification circuit, and generate a boost instruction to increase the power supply voltage output by the PMIC module to the second target module, and can speed up the voltage regulation speed.

[0084] Based on a concept similar to the voltage adjustment method provided in any of the above embodiments, an embodiment of the present application further provides a voltage regulation module.

[0085] like Figure 6 As shown, the embodiment of the present application provides a voltage regulating module 100, which may include: A first target module 110, a second target module 120, a target power amplification module 130, a control module 140 and a PMIC module 150; the first target module 110 and the second target module 120 are both powered by the PMIC module 150; Wherein, the first target module 110 is connected to the target power amplification module 130 and the control module 140 respectively; The control module 140 is coupled to the control terminal SPMI of the PMIC module 150, and the voltage output terminals BUCK1 and BUCK2 of the PMIC module 150 are connected to the first target module 110 and the second target module 120 respectively; The control module 140 is used to implement the voltage adjustment method provided by the above method embodiment.

[0086] Among them, reference Figure 6The voltage output terminal of the PMIC module 150 may include multiple, for example, the multiple voltage output terminals may be numbered, and the voltage output terminal of the PMIC module 150 may include a BUCK1 port and a BUCK2 port. The BUCK1 port of the PMIC module 150 is connected to the first target module 110, and the PMIC module 150 outputs the power supply voltage to the first target module 110 through the BUCK1 port; the BUCK2 port of the PMIC module 150 is connected to the second target module 120, and the PMIC module 150 outputs the power supply voltage to the second target module 120 through the BUCK2 port.

[0087] In an embodiment of the present application, the control module 140 can implement the voltage adjustment method provided by the above-mentioned method embodiment. When the control module 140 detects a control command instructing the target power amplifier module to work, the control module 140 generates a boost command, and based on the boost command, increases the output voltage provided by the PMIC module to the second target module. Since the output voltage provided by the PMIC module to the second target module is increased, the anti-interference ability of the second target module can be improved, thereby avoiding stability problems caused by interference of the target power amplifier module to the second target module, and improving the system stability of the electronic device.

[0088] In order to improve the accuracy of the boost command, in a specific embodiment, as Figure 7 As shown, the voltage regulating module 100 may further include at least one sensor 160 , and the at least one sensor 160 is connected to the control module 140 .

[0089] Among them, the sensors may include but are not limited to: light sensors, distance sensors, gravity sensors, acceleration sensors, fingerprint sensors, gyroscope sensors, magnetic field sensors, air pressure sensors, temperature sensors, humidity sensors, pressure sensors, heart rate sensors, optical sensors and infrared sensors, etc. This application does not limit the specific types of sensors.

[0090] In this way, the present application can also determine the target scene information of the electronic device based on at least one sensor data, and generate a boost command based on the target scene information, thereby further improving the accuracy of the boost command.

[0091] In practical applications, the control module 140 may be a central processing unit (CPU) inside a SoC chip, or a microcontroller unit (MCU), or a microprocessor unit (MPU), or a separate control chip, etc. The present application does not limit the specific type of the control module 140. An example is given below.

[0092] In a specific embodiment, Figure 8As shown, the control module 140 is a central processor 141 disposed inside the SoC chip 200 ; the first target module 110 and the second target module 120 may also be disposed inside the SoC chip 200 .

[0093] In this way, the present application can also use the central processor 141 to monitor the control command of the first target module 110 to the target power amplifier module 130 through the software channel, generate a boost command when the control command indicates that the target power amplifier module 130 is working, and then send the boost command to the PMIC module through the SPMI bus to control the PMIC module to increase the power supply voltage output to the second target module 120.

[0094] For example, Fig. 9 As shown, the SoC chip 200 further includes: a memory 201, an arbitrator 202, an AVS sensor 203, and an AVS controller 204. The memory 201, the arbitrator 202, the AVS sensor 203, the AVS controller 204, and the central processor 141 can be used to implement an AVS voltage regulation mechanism.

Among them, the PMIC module 150 outputs the power supply voltage to the memory module 121 through the voltage output port BUCK5; the PMIC module 150 outputs the power supply voltage to the camera module 122 through the voltage output port BUCK6.

[0101] It should be noted that the BUCK1 port, the BUCK2 port, the BUCK3 port, the BUCK4 port, the BUCK5 port, and the BUCK6 port generally refer to a type of voltage output ports of the PMIC module 150 , rather than specifically referring to a specific port.

[0102] In this way, Fig. 9 As shown, the present application can also be implemented by the central processor 141 to monitor the control commands of the RF communication module 111, the WiFi module / Bluetooth module / GPS module 112, the Beidou module 113 and the audio processing module 114 to various PA modules through a software channel, and generate a boost command when the control command indicates that at least one PA module is working, and then send the boost command to the PMIC module through the SPMI bus to control the PMIC module to increase the power supply voltage output to the memory module 121 and the camera module 122, which can improve the anti-interference ability of the memory module 121 and the camera module 122, avoid the stability problems caused by external interference of the memory module 121 and the camera module 122, and improve the system stability of the electronic device.

[0103] In another specific embodiment, in order to speed up the voltage regulation speed, Fig.10 As shown, the control module 140 is a control chip 142 disposed between the control terminal SPMI of the PMIC module 150 and the first target module 110; The control chip 142 has an input terminal and an output terminal; the first target module 110 is connected to the input terminal of the control chip 142 via a target control line L, and the output terminal of the control chip 142 is connected to the control terminal SPMI of the PMIC module 150; The target control line L is a control line between the first target module 110 and the target power amplification module 130 .

[0104] In this way, the control chip 142 can directly obtain the control command of the first target module 110 to the target power amplifier module 130 from the target control line L, detect the working status of the target power amplifier module 130 through the hardware identification circuit, and generate a boost instruction to increase the power supply voltage output by the PMIC module 150 to the second target module 120, and can speed up the voltage regulation speed.

[0105] For example, Fig.11 As shown, the SoC chip 200 further includes: a memory 201, an arbitrator 202, an AVS sensor 203 and an AVS controller 204. The AVS sensor 204 is used to detect the supply voltage value output by the PMIC module 150, the AVS sensor 204 is connected to the AVS controller 203, the central processing unit 142 is connected to the memory 201, the AVS controller 204 and the central processing unit 142 are both connected to the arbitrator 202, and the arbitrator 202 is connected to the control end SPMI of the PMIC module 150 via the SPMI bus.

[0106] Among them, the memory 201, the arbitrator 202, the AVS sensor 203, the AVS controller 204 and the central processor 141 can be used to implement the AVS voltage regulation mechanism.

[0107] Among them, Fig.11 As shown, the first target module 110 may include: a radio frequency communication module 111 , a WiFi module / Bluetooth module / GPS module 112 , a Beidou module 113 and an audio processing module 114 .

[0108] Among them, Fig.11 As shown, the target power amplification module 130 may include: a radio frequency communication PA module 131 , a WCN PA module 132 , a Beidou PA module 133 and an audio PA module 134 .

[0109] Among them, the radio frequency communication PA module may include but is not limited to at least one of a 5G power amplifier, a 4G power amplifier, a 3G power amplifier and a 2G power amplifier.

[0110] Among them, Fig.11 As shown, the second target module 120 may include: a memory module 121 and a camera module 122 .

[0111] In this way, Fig.11As shown, the present application can also use the control chip 142 to directly monitor the control commands of the RF communication module 111, the WiFi module / Bluetooth module / GPS module 112, the Beidou module 113 and the audio processing module 114 to various PA modules, generate a boost command when the control command indicates that at least one PA module is working, and then send the boost command to the PMIC module through the SPMI bus to control the PMIC module to increase the power supply voltage output to the memory module 121 and the camera module 122, which can improve the anti-interference ability of the memory module 121 and the camera module 122, avoid the stability problems caused by external interference to the memory module 121 and the camera module 122, improve the system stability of the electronic device, improve the AVS voltage regulation mechanism, and speed up the voltage regulation speed.

[0112] For example, Fig.12 As shown, the control chip 142 may include a LUT unit 1421, the target power amplifier module 130 is connected to the LUT unit 1421 via the target control line L and the input end of the control chip 142, and the LUT unit 1421 is connected to the control end SPMI of the PMIC module 150 via the output end of the control chip 142; The LUT unit 1421 stores a mapping relationship between target information and a preset voltage; the target information includes at least one of scene information and an operating mode of the PMIC module; The preset voltage is used to determine the boost amplitude of the boost command.

[0113] Among them, Fig.12 As shown, the control chip 142 may further include a flash memory unit 1422 , a clock unit 1423 , and a power supply management unit 1424 , and the flash memory unit 1422 , the clock unit 1423 , and the power supply management unit 1424 are respectively connected to the LUT unit 1421 .

[0114] Among them, the input end of the control chip 142 includes interfaces such as I2C interface, PCIE interface, RFFE interface, and GPIO interface.

[0115] Among them, the I2C interface, RFFE interface, PCIE interface, and GPIO interface are used to receive the working status information of sensors, RF PA, WIFI, Beidou and other modules, and provide input to the LUT unit.

[0116] The output end of the control chip 142 includes an SPMI interface. The output end of the control chip 142 can output an SPMI_OUT signal. The SPMI_OUT signal can be a boost instruction. Different boost instructions may correspond to different output voltage values.

[0117] The input end of the control chip 142 can monitor the signals from each module to the PA control path, and the output is a set of SPMI buses. The internal lookup table controls the PMIC module by judging the input situation and outputting the corresponding SPMI signal. The format of the internal lookup table can be referred to in Table 1 below:

[0118] Table 1 Among them, the LUT (Look Up Table) unit is an internal lookup table of the control chip 142. According to the input of the I2C interface, RFFE interface, PCIE interface, GPIO interface and other interfaces, it judges the current working scenario and then predicts the upcoming interference source, thereby raising the voltage in advance and improving stability.

[0119] It should be noted that the control signals of various modules connected to the input end of the control chip 142 are different, generally including RFFE, PCIE, I2C, and GPIO. For example, the I2C interface is used to monitor sensor data; the I2C interface is also used to monitor sensor data and the control signal of the audio processing module 114 to the PA control path, the PCIE interface is used to monitor the signal of the WiFi module / Bluetooth module / GPS module 112 to the PA control path, the RFFE interface is used to monitor the signal of the radio frequency communication module 111 to the PA control path, and the GPIO interface is used to monitor the signal of the Beidou module 113 to the PA control path.

[0120] The flash memory unit 1422 is used to store IC firmware (eg, the operating program of the control chip), and the content in the flash memory unit can be written and erased through the JTAG interface.

[0121] The power supply management unit 1424 is used to control the power supply management of the analog part 3.3V, the digital interface part 1.8V and the digital core part 0.9V of the internal control chip 142. When the power supply is abnormal or the power-on timing is wrong, it has the function of resetting the hardware of the control chip 142.

[0122] The clock signal CLOCK input by the clock unit 1423 can be used as a reference clock for the internal digital circuit, and its operating frequency determines the processing speed of the control chip 142 .

[0123] In this way, in the embodiment of the present application, the control chip 142 can directly monitor the control commands of the RF communication module 111, the WiFi module / Bluetooth module / GPS module 112, the Beidou module 113 and the audio processing module 114 to various PA modules. When the control command indicates that at least one PA module is working, the lookup table inside the LUT unit is compared to generate a boost command (for example, an SPMI_OUT signal), and then the boost command is sent to the PMIC module through the SPMI bus to control the PMIC module to increase the supply voltage output to the memory module 121 and the camera module 122.
