Abstract
PURPOSE: To cancel the distortion efectively, by detecting the distortion generated in an amplifying circuit by a distortion detecting circuit and adding this detection output to an input signal.
CONSTITUTION: A distortion generated in an amplifying circuit 7 consisting of bias power sources 1 and 2, transistors 3 and 4, and their emitter resistances 5 and 6 is detected by a distortion detecting part 13a consisting of emitter resistances 5 and 6 and resistances 15a, 15b, 16, and 18 and a distortion detecting part 13b consisting of a differential amplifier 17. This detection output and an input signal are added by an adding circuit 14 inserted between the input terminal of the amplifying circuit 7 and an input terminal 9 to which a signal to be amplified is applied, thus cancelling the distortion.
