ABSTRACT:
An amplifier circuit which amplifies an input signal with substantially zero distortion and can stably operate even at high frequencies is provided. A signal proportional to an input signal supplied to an input terminal is applied to an input terminal of a main amplifier. An output signal of this main amplifier is supplied through an impedance circuit to one of input terminals of a differential amplifier the other input terminal of which is supplied with the input signal to be amplified. An output signal of this differential amplifier is fed to a reference voltage input terminal of the main amplifier to determine a voltage potential of the input terminal of the main amplifier when a signal level of the input signal is zero, thereby distortion generated in the main amplifier being canceled.
