Abstract

PURPOSE: To reduce the remaining voltage at the negative side of a quasi-complementary PP circuit, by providing a level shift diode between the base of an npn transistor, forming an inversion output, and an output middle-point terminal.
CONSTITUTION: A signal from preamplifier 1 is amplified by transistor Q1. As the collector output of Q1 increases above a middle-point voltage, signals shifted in level by diodes D1 and D2 are inputted to output transistors Q5 and Q6, and consequently a positive half cycle is amplified. When the collector output of Q1 is lower than the middle-point potential, output transistors Q2' and Q4 are driven through inversion output transistor Q3' to amplify a negative half cycle.
