Abstract

The invention discloses an equalizer circuit, an equalizer and an electric appliance, wherein the equalizer circuit comprises a differential amplifying circuit, a bandwidth amplifying circuit and a buffer circuit, a first output end of the differential amplifying circuit is connected with a first end of the bandwidth amplifying circuit, a second output end of the differential amplifying circuit is connected with a second end of the bandwidth amplifying circuit, a first output end of the buffer circuit is connected with a first end of the bandwidth amplifying circuit, and a second output end of the buffer circuit is connected with a second end of the bandwidth amplifying circuit; the differential amplifying circuit receives the attenuation signal, amplifies the attenuation signal to obtain an adjustment signal, and outputs the adjustment signal to the bandwidth amplifying circuit; the bandwidth enlarging circuit enlarges the adjusting signal to obtain a reference signal and outputs the reference signal to the buffer circuit; and the buffer circuit amplifies and outputs the reference signal to obtain a target signal, thereby realizing the compensation of the attenuation signal.
