Двотактний симетричний підсилювач струму

Abstract

A pull-push balanced current amplifier relates to pulse technique and can be used in analog-to-digital converters and digital instruments. The current amplifier comprises first and second current sources, a feedback resistor, positive and negative buses, zero bus and six transistors. In addition, first and second current compensators, bi-directional current reflector, first and second current switchers are incorporated. All said elements are interconnected in an appropriate manner. In the amplifier operation accuracy is increased due to fitting coefficients of current amplification of upper and low stages of amplifier cascades, also linearity improves due to automation of DC balancing process of amplification stages operation points that extends area of utilizations in different devices of pulse and computation engineering.
