ABSTRACT:
An amplifier with substantially no distortion is provided, the amplifier having input and output terminals and an amplification means for amplifying an input signal applied to the amplification means. A distortion detection circuit is provided for detecting distortion generated in the amplification means in accordance with the input and output signals of the amplification means. The output of the distortion detection circuit is applied to an addition circuit where the output of the distortion detection circuit is added to an input signal applied to the input terminal of the amplifier. The added signal is then supplied as the input signal of the amplification means for the cancellation of distortion generated in the amplification means.
