Class AB Power Amplifiers Learn About Electronics Class AB Power Amplifiers. The class AB push pull output circuit is slightly less efficient than class B because it uses a small quiescent current flowing, to bias the transistors just above cut off as shown in Fig. 5.5.1, but the crossover distortion created by the non linear section of the transistor’s input characteristic curve, near to cut off in class B is overcome. Class D amplifier A class D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifiers.They operate by rapidly switching back and forth between the supply rails, being fed by a modulator using pulse width, pulse density, or related techniques to encode the audio ... Power amplifier classes Power amplifier classes are, in electronics, letter symbols applied to different power amplifier types. The class gives a broad indication of an amplifer's characteristics and performance. The classes are related to the time period that the active amplifier device is passing current, expressed as a fraction of the period of a signal waveform applied to the input.
