Двотактний симетричний підсилювач струму

Abstract

A push-pull balanced amplifier relates to pulse technique and may be used in analogue-to-digital converters and digital instruments. In push-pull amplifier an operating point voltage setting unit and a push-pull amplification stage with input currents phase splitting having corresponding connection are incorporated. Usage of the push-pull amplification stage with input currents phase splitting provides increase of amplification factor both as current and voltage. An operating point voltage setting unit together with first and second transistors in diode connection provides the necessary level of operating point voltage of third and fourth transistors correspondingly. In the said push-pull balanced amplifier amplification of input signal amplification factor is achieved.
