Abstract

An amplifier deviceincludes: a distortion compensation sectionthat performs distortion compensation for an input signal x to an amplifierby digital signal processing; and a separation sectionthat separates an output signal from the amplifierinto an I signal as an analog signal component including phase information of the output signal and an analog signal component including power information of the output signal. The distortion compensation sectionperforms distortion compensation for the amplifier, based on 1-bit signals obtained by expressing, in 1 bit, the analog I signal and the analog signal component including the power information of the output signal, respectively.
