Abstract
A parallel amplifier and an offset capacitance voltage control loop are disclosed. The parallel amplifier has a parallel amplifier output, which is coupled to an envelope tracking power supply output via an offset capacitive element. The offset capacitive element has an offset capacitive voltage. The offset capacitance voltage control loop regulates the offset capacitive voltage, which is adjustable on a communications slot-to-communications slot basis.
