ABSTRACT:
An audio amplifier reduces crossover distortion typical of class AB push-pull amplifiers by including means for preventing either of the output transistors from being cut off during any portion of the audio waveform. This desirably eliminates sharp discontinuities associated with the transfer function of the amplifier. The circuit includes two base-emitter voltage multipliers and a nonlinear transconductance feedback amplifier.
