Title: Amplifying circuit
Inventor: KOMINAMI YASUO
IPC: H03F3/20
Filed: 1981-08-28
Abstract: PURPOSE:To prevent waveform distortion during small signal input by providing a current by-passing means connected in parallel to a collector-emitter path, and turning off one output transistor (TR) when a signal has small amplitude and also putting the other output TR in emitter follower operation. CONSTITUTION:When an input signal has a high voltage amplitude level, TRs Q4 and Q5 operate as a normal SEPP circuit. When the input signal Vin has a low amplitude level, the majority of the emitter current of the output TRQ4 flows to a current by-passing resistance R0, and a little current flows to the output TRQ5. In this state, when a positive half-cycle component of the input signal having the low amplitude level is supplied, the Q5 is almost turned off and the Q4 is turned on by a base current supplied from a constant current circuit 6. Thus, the SEPP circuit 4 operates as an emitter follower circuit wherein only the Q4 operates substantially. When a negative half-cycle component is supplied, the Q4 does not operate and the Q5 constitutes an emitter follower circuit.
