Двотактний симетричний підсилювач-комутатор струмів

Abstract

A balanced symmetrical amplifier- current commutator comprises two current sources, thirty eight transistors, two resistors, positive and negative supply buses, an input bus, an output bus, a neutral bus. In addition, thirty ninth, fortieth, forty first and forty second transistors are incorporated in such a way that collector of twenty eighth transistor is connected to bases and collectors of thirty ninth and forty first transistors, collector of twenty ninth transistor is connected to emitters of fortieth and forty second transistors, the first and second outputs of a current commutator are connected to emitter of thirty ninth transistor and a base and collector of fortieth transistor accordingly, emitter of forty first and also collector and base of forty second transistor are connected to the output bus.
