Abstract

An amplifier includes a power amplifier that amplifies an input signal, a VI detection circuit that is connected to a rear stage of the power amplifier to detect power of an output signal of the power amplifier, and a controller that turns on the power amplifier when the input signal is inputted to the power amplifier, turns off the power amplifier when the input signal is not inputted to the power amplifier, and turns on the power amplifier when the VI detection circuit detects a voltage that exceeds a predetermined value when the power amplifier is in off state.
