Abstract
A power amplifier includes a first amplifier configured to output a signal based on a difference between an input signal and a feedback signal; a second amplifier that amplifies the power of the signal output from the first amplifier and outputs the amplified signal; a first feedback circuit that feeds the signal output from the second amplifier back to the first amplifier; a third amplifier that amplifies the power of the signal output from the second amplifier and outputs the amplified signal; and a second feedback circuit that feeds the signal output from the third amplifier back to the first amplifier, in which the feedback signal is a signal obtained by combining an output signal of the first feedback circuit with an output signal of the second feedback circuit.
