Abstract
PURPOSE: To prevent the distortion rate from being degraded by the influence of a feedback capacity, by changing the common emitter current of transistors, which constitute the differential amplifier in the input stage, in the same phase as an input or output signal.
CONSTITUTION: The input signal applied to an input terminal 1 is amplified by a differential amplifier 4 consisting of FETs 2 and 3 and is amplified by an amplfying circuit 9 and appears at an output terminal 12. A part of the output is fed back through a resistance R10 to the gate of the FET3. The emitter of a transistor (TR) 8 in the output side and the base of a TR5 for constant current are connected through a capacitor C2, and the TR5 for constant current is controlled by a part of the output current flowed between the emitter and the collector of the TR8.
