Abstract
A power amplifier include an amplifier including at least one field effect transistor (FET) that operates in an amplifying stage configured to amplify an input signal, and a body controller configured to control a bias voltage of a body terminal of the FET based on a power of the input signal. The body controller performs controlling so that the bias voltage of the body terminal is reduced in response to the power of the input signal being increased. Accordingly, such a power amplifier exhibits improved linearity.
