摘要：A power amplifier controller circuit controls a power amplifier based upon anamplitude correction signal indicating the amplitude difference between the amplitude ofthe input signal and an attenuated amplitude of the output signal. The power amplifiercontroller circuit comprises an amplitude control loop and a phase control loop. The
amplitude control loop adjusts the supply voltage to the power amplifier based uponthe amplitude correction signal. The amplitude correction signal may also be split intotwo or more signals with different frequency ranges and provided respectively todifferent types of power supplies with different efficiencies to generate the adjustedsupply voltage to the power amplifier. The phase control loop adjusts the phase of theinput signal based upon a phase error signal indicating a phase difference betweenphases of the input signal and the output signal to reduce phase distortion generated bythe power amplifier.
