Abstract

PURPOSE:To improve a distortion characteristic, by connecting the second PP amplifier, which has the gain characteristic in the cut-off part of the first PP amplifier, in parallel to the first efficient PP amplifier. CONSTITUTION:The first PP amplifier 1 is an efficient, for example, class ''B'' amplifier, and the second PP amplifier connected in parallel to this first PP amplifier is operated as, for example, a class ''A'' amplifier during cut-off of amplifier 1. By this constitution, though crossover distortion and switching distortion are included in the output signal of amplifier 1, distortion from amplifier 1 can be eliminated because amplifier 2 has a gain even in the crossover part.
