Abstract
A power amplifying apparatus includes an amplifier configured to amplify an input signal and supply a load with the amplified input signal, a current detecting circuit, disposed at an output stage of the amplifier, configured to detect a current of an output signal from the amplifier, a current feedback circuit configured to provide feedback of the detected current of a certain feedback amount, a voltage feedback circuit configured to provide feedback of a voltage of the output signal of a certain feedback amount, and an adjuster configured to adjust the input signal using the feedback current and the feedback voltage.
