Abstract

PURPOSE:To prevent occurrence of the switching distortion by providing the compensating circuit to the B-class SEPP power amplifying circuit and thus always maintaining the on-state for all transistors. CONSTITUTION:TR14, in which the emitter is connected to the emitter of transistor (TR) TR1, the collector is connected to the joint point of resistances 4 and 5 and the base is connected to the joint point of resistances 3 and 4 as well as to the collector of TR9 via resistance 15 respectively, is added to the B-class SEPP power amplifying circuit. In the same way, TR16, in which the emitter is connected to the emitter of TR8, the collector is connected to the joint point of resistances 11 and 12 and the base is connected to the joint point of resistances 10 and 11 as well as to the collector of TR2 via resistance 17 respectively, is added to the above-mentioned power amplifying circuit. By the compensating circuit thus constituted, the voltage reduction can be compensated between the base and the emitter of TR1, 8 under application of the signals. As a result, all transistors can always be maintained at the on-state, thus preventing occurrence of the switching distortion.
