Abstract
PURPOSE: To obtain a very stably amplifying function without distortion, by constituting an amplifier with a grounded emitter amplifying circuit and a distortion cancelling circuit.
CONSTITUTION: An amplifier consists of a grounded emitter amplifying circuit 3 and a distortion cancelling circuit 9. A distortion between an input signal 4 supplied to the base of a transistor TR 1 constituting the grounded emitter amplifying circuit 3 and a signal obtained in the emitter is detected by the distortion cancelling circuit 9, and this detection output is added to the input signal 4. Thus, only distortion components generated in the grounded emitter amplifying circuit 3 are used to cancel the distortion effectively, and therefore, a very stable amplifying function without distortion is obtained.
