Complementary push-pull amplifier

摘要

A complementary push-pull amplifier comprising a pair of complementary transistors each of which is connected to a voltage source through a relatively large resistance and having the base biased with a voltage formed from the emitter-collector voltage of the transistor. Means for equalizing the amplitudes of second order distortion caused by the respective transistors is provided in a portion of the circuit other than the emitter circuit. The collector current is stabilized by the relatively large resistance connected to the collector and the asymmetry of the pair of transistors can be corrected by the amplitude equalizing means for cancellation of the second order distortion.
