Class-D amplifier: History, Applications & Measurement

A class-D amplifier, or switching amplifier, is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs, increasingly GaN FETs) operate as electronic switches, and not as linear gain devices as in other amplifier classes. Class-D amplifiers operate by rapidly switching back and forth between the power supply rails, using…
