Distortion in Class AB Power Amplifiers

The transition from class A to class B in power amplifiers has been investigated with regard to distortion. It is shown that this transition triggers off one of two different nonlinearity mechanisms dependent upon the realization of the output stage. The theoretically derived equations are shown together with measured parameters of a typical design. The results reveal large amounts of distortion reaching a maximum at medium power levels.
