Abstract

PURPOSE:To prevent charge current of condenser from flowing into the base of output transistor by connecting condenser between the base of output transistor of B-class amplifier and output terminal of amplifier. Thus, increase of power loss is avoided, with less distortion and with increased efficiency.
