    摘要: A power amplifier includes a class A power amplifier and a class B power amplifier driven by the same input signal. The class A amplifier includes a pair of load driving power amplifying elements, and a further pair of amplifying elements serves to drive the power amplifying elements. To obtain good operating characteristics and reduce distortion, the further pair of elements are powered by power supplies for the class B amplifier.
