Background
The radio frequency power amplifier is an important component of the electronic terminal, and the electronic terminal can obtain higher radio frequency output power through the radio frequency power amplifier. In order to obtain a sufficiently large radio frequency output power, the voltage of the power amplifier can be adjusted in real time to adapt to the change of the power of the radio frequency power amplifier, so that the working efficiency of the radio frequency power amplifier is improved. Wherein the higher the power of the radio frequency power amplifier, the higher the required voltage.
Conventionally, the industry employs an Average Power Tracking (APT) technique or an Envelope Tracking (ET) technique to track Power variation of the rf Power amplifier, so as to adjust the voltage of the Power amplifier in real time, thereby improving the working efficiency of the rf Power amplifier.
The APT technology needs a longer time interval to reflect the requirement of power on voltage, the voltage correction speed is low, the calculation power consumption is low, and the working efficiency of the power amplifier can be effectively improved; the ET technology can track radio frequency signals and control voltage at a higher speed, the voltage correction speed is high, the calculation power consumption is high, the frequency is high, and the working efficiency of the power amplifier can be efficiently improved.
In order to improve the voltage correction speed and reduce the power consumption, the prior art combines the characteristics of the APT technique and the ET technique, obtains the approximate turning points of the efficiency of the power amplifier when the APT technique and the ET technique are used by statistical measurement, and calculates to obtain the corresponding power turning points.

Example 2
An embodiment of the present invention provides a voltage calibration method for a power amplifier, which is applied to an electronic terminal, where the electronic terminal has a power amplifier for radio frequency output, and as shown in fig. 2, the voltage calibration method for a power amplifier includes:
s201, the electronic terminal shortens the voltage calibration time interval of the APT technology according to a preset adjustment interval.
The voltage calibration time interval is a time interval for reflecting the voltage requirement of the power amplifier of the electronic terminal when the voltage of the power amplifier in the electronic terminal is calibrated by adopting an APT technology or an ET technology.
For example, the APT technique needs a longer time interval to reflect the power requirement on the voltage, that is, the APT technique has a longer voltage calibration time interval and a slower voltage calibration speed, but the power consumption of the calculation for performing the voltage calibration by using the APT technique is low, which can effectively improve the working efficiency of the power amplifier; the ET technology can track the radio frequency signal and control the voltage at a higher speed, namely the ET technology has a shorter voltage calibration time interval and a high voltage correction speed, but the ET technology is large in power consumption and high in frequency in calculation of voltage calibration, so that the working efficiency of the power amplifier can be improved efficiently.
It should be noted that S201 is optional, wherein, since the voltage calibration time interval of the APT technique is greater than the voltage calibration time interval of the ET technique, the electronic terminal may adjust the voltage calibration time interval of the APT technique. Specifically, the electronic terminal may shorten the voltage calibration time interval of the APT technique according to the preset adjustment interval to reduce a time difference between the voltage calibration time interval of the APT technique and the voltage calibration time interval of the ET technique, so as to improve smoothness of efficiency variation of the power amplifier of the electronic terminal when the APT technique and the ET technique are used for voltage calibration.
S202, the electronic terminal obtains a power consumption set when the voltage of a power amplifier of the electronic terminal is calibrated by adopting the adjusted APT technology, namely the first power consumption set.
The first power consumption set may be a power consumption set when the electronic terminal calibrates the voltage of the power amplifier by using the adjusted APT technique. The first set of power consumptions may include values of power consumption for different periods of time while the power amplifier voltage is calibrated using the adjusted APT technique.
S203, after the electronic terminal obtains the voltage of the power amplifier of the electronic terminal calibrated by using the adjusted APT technique, the working efficiency set of the power amplifier of the electronic terminal is the first working efficiency set.
The first working efficiency set may be a working efficiency set of the power amplifier after the electronic terminal calibrates the voltage of the power amplifier by using the adjusted APT technique.
S204, the electronic terminal acquires ET feedback information of the electronic terminal, wherein the ET feedback information comprises: a second set of power consumptions and a second set of operating efficiencies.
The second power consumption set is a power consumption set when the electronic terminal calibrates the voltage of the power amplifier by adopting an ET technology; the second working efficiency set is the working efficiency set of the power amplifier after the electronic terminal adopts the ET technology to calibrate the voltage of the power amplifier.
It should be noted that, in this embodiment, S201 to S203 may be executed first, and then S204 may be executed; or S204 can be executed first, and then S201-S203 can be executed; S201-S203 and S204 may also be performed simultaneously. The embodiment of the invention does not limit the execution sequence of S201-S203 and S204.
S205, the electronic terminal acquires a work efficiency turning point set in the first work efficiency set and the second work efficiency set.
The working efficiency turning point set comprises at least one working efficiency value, and all the working efficiency values contained in the working efficiency turning point set are values of the working efficiency turning points when the voltage of the power amplifier is respectively calibrated by adopting the adjusted APT technology and the adjusted ET technology.
Specifically, the electronic terminal may determine a value with the highest relative operating efficiency in the first operating efficiency and the second operating efficiency as an efficiency turning point (i.e., a first efficiency value) in combination with the first power consumption set and the second power consumption set, so as to ensure that the power consumption consumed by calibrating the voltage of the power amplifier of the electronic terminal using the adjusted APT technique or ET technique is relatively the lowest by using the first efficiency value as a critical efficiency value (i.e., an efficiency turning point), thereby improving the operating efficiency of the power amplifier.
S206, the electronic terminal determines a first efficiency value in the working efficiency turning point set according to the first power consumption set and the second power consumption set, wherein the first efficiency value is the working efficiency value with the lowest power consumption in the working efficiency turning point set.
The electronic terminal can compare the working efficiency values in the working efficiency turning point set, and the working efficiency value with the lowest working efficiency value in the working efficiency turning point set is used as the first efficiency value.
S207, when the working efficiency of the power amplifier is the first efficiency value, the electronic terminal obtains a power value of the power amplifier, and the power value is the first power value.
After determining the first efficiency value, the electronic terminal may calculate, according to power consumption, working efficiency and the like corresponding to the first efficiency, a power value of a power amplifier of the electronic terminal, that is, the first power value, when the working efficiency of the power amplifier of the electronic terminal is the first efficiency value.
It should be noted that, when the adjusted APT technique or ET technique is used to calibrate the voltage of the power amplifier of the electronic terminal, it is determined that the first efficiency value is used as the critical efficiency value, and the power consumption consumed by calibrating the voltage of the power amplifier of the electronic terminal respectively by using the APT technique or ET technique is relatively lowest, so that if the first power value calculated according to the first efficiency value is used as the critical power value, i.e. the power turning point, and the adjusted APT technique or ET technique is used to calibrate the voltage of the power amplifier of the electronic terminal respectively, the calibration of the voltage of the power amplifier of the electronic terminal can be quickly completed at a lower power consumption, and the working efficiency of the power amplifier can be improved.
Specifically, the electronic terminal may determine a magnitude relationship between a real-time power of a power amplifier of the electronic terminal and a first power value, and select an ET technique to calibrate a voltage of the power amplifier of the electronic terminal when the electronic terminal determines that the real-time power of the power amplifier of the electronic terminal is greater than the first power value; and when the electronic terminal determines that the real-time power of the power amplifier of the electronic terminal is smaller than the first power value, selecting the adjusted APT technology to calibrate the voltage of the power amplifier of the electronic terminal. The method of the embodiment of the present invention may further include S208 to S211:
and S208, the electronic terminal acquires the real-time power requirement and the real-time power of the power amplifier.
The real-time power requirement of the power amplifier of the electronic terminal is the real-time power required by the current normal operation of the power amplifier of the electronic terminal, and the real-time power of the power amplifier of the electronic terminal is the current operation power of the power amplifier of the electronic terminal.
S209, the electronic terminal determines the size relation between the real-time power of the power amplifier and the first power value.
Specifically, the electronic terminal may compare the real-time power value of the power amplifier of the electronic terminal with the first power value, and if the electronic terminal determines that the real-time power of the power amplifier of the electronic terminal is greater than the first power value, S210 is executed; if the electronic terminal determines that the real-time power of the power amplifier of the electronic terminal is less than the first power value, S211 is executed.
S210, the electronic terminal selects an ET technology to calibrate the voltage of the power amplifier so that the real-time power of the power amplifier meets the real-time power requirement of the power amplifier, and the operation is finished.
The ET technology is adopted to calibrate the voltage of the power amplifier of the electronic terminal, so that the requirement of the real-time power of the power amplifier of the electronic terminal on the voltage can be quickly reflected at a small time interval, and the voltage can be quickly adjusted.
S211, the electronic terminal selects the APT technology with the adjusted voltage calibration time interval to calibrate the voltage of the power amplifier so that the real-time power of the power amplifier meets the real-time power requirement of the power amplifier, and the method is finished.
The adjusted APT technology is adopted to calibrate the voltage of the power amplifier of the electronic terminal, so that the requirement of the real-time power of the power amplifier of the electronic terminal on the voltage can be quickly reflected at a larger time interval, the voltage adjusting speed is lower, but the calculation power consumption of the adjusted APT technology is lower, and therefore when the electronic terminal determines that the real-time power of the power amplifier of the electronic terminal is smaller than the first power value, the technology is selected to calibrate the voltage of the power amplifier of the electronic terminal, and the voltage calibration power consumption can be reduced.
According to the voltage correction method of the power amplifier provided by the embodiment of the invention, the electronic terminal of the power amplifier with the radio frequency output function can acquire the APT feedback information and the ET feedback information of the power amplifier; determining a first power value according to the APT feedback information and the ET feedback information; and according to the first power value, combining the real-time power requirement and the real-time power of the power amplifier, and selecting an APT technology or an ET technology by adopting a preset power tracking strategy to calibrate the voltage of the power amplifier. Compared with the prior art that the power tracking technology is selected according to the same power turning point obtained by statistics when the voltages of the power amplifiers of all the electronic terminals are calibrated, the first power value can be determined according to the working characteristics of different electronic terminals, and the corresponding power tracking technology is selected according to the real-time power requirement of the electronic terminals, so that the working efficiency of the power amplifiers can be effectively improved.
