Двотактний симетричний підсилювач струму

Abstract

A push-pull balanced current amplifier relates to pulse technique and may be used in analogue-digital converters and digital measuring devices. A first and a second generators of base currents and seventh and eight transistors with corresponding connections are incorporated. First and second current sources provide the required DC mode for amplifier stages. A feedback resistor sets the required amplification ratio. Positive and negative power buses and a zero bus provide the required voltage for circuit feeding. Application of the proposed amplifier increases accuracy of input signal transmission of circuit output and decreases an input offset current
