Abstract
A negative-feedback amplifier prevents deterioration of the open-loop gain and the distortion improvement effect despite changes in a sending frequency by demodulating a baseband signal from a carrier and an output signal of an amplifier and a demodulated baseband signal. The negative-feedback amplifier includes a correcting member for correcting a phase error of the demodulated baseband signal caused by a delay in the amplifier for each change of a sending frequency of the carrier.
