Power amplifier and method for controlling power amplifier

Abstract

A power amplifier includes a first transistor, a second transistor and a bias voltage generator. The first transistor includes a gate electrode, a first electrode and a second electrode, where the gate electrode is coupled to a signal input terminal of the power amplifier. The second transistor includes a gate electrode, first electrode and a second electrode, where the second electrode of the second transistor is connected to the first electrode of the first transistor, and the first electrode of the second transistor is coupled to a signal output terminal of the power amplifier. The bias voltage generator is coupled to the second transistor, and is utilized for generating a bias voltage to bias the electrode of the second transistor, where the bias voltage is less than a supply voltage of the power amplifier.
