Abstract

PURPOSE:To achieve class A operation with a simple circuit, by providing a current source consisting of resistors between bases of an output transistors. CONSTITUTION:A signal voltage E1 appears at the middle point of diodes D1, D2 corresponding to an input signal. In this case, transistors (TR) Q1, Q2 are in class B biased with the diodes D1, D2 and signal currents I1, I2 flow. Since a resistor R2 acts llke a base bias resistor and bias currents Ib3, Ib4 flow. Thus, TRs Q3, Q4 act like class A push-pull operation of common emitter.
