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.W2DTC's Homebrew Class 'A' RF Amplifier
