Abstract
A power amplifying apparatus includes a first bias circuit configured to generate a first bias current by adding a boost current to a base bias current generated from a reference current, a first amplification circuit configured to receive the first bias current and amplify a signal input through an input terminal of the first amplification unit to output a first amplified signal, and a bias boosting circuit configured to generate the boost current, based on a magnitude of a harmonic component in the amplified signal output from the first amplification circuit.
