Class D is the only option for combining all these requirements together. A typical Class D power amplifier consists of a sawtooth waveform generator, comparator (based on an OPAMP), switching circuit, and a low pass filter. The block diagram of a Class D amplifier is shown in the figure below. Sawtooth waveform generator.

Class D amplifier circuit Class D amplifier. Class D amplifier is a type of amplifier where the power devices (MOSFET or transistor) are operated as switches. There will be only two states (ON/OFF) for these switches and no time is wasted for the transition from one stage to another. The working of a class D amplifier is as follows.

There are many classes of audio amplifiers; A, B, AB, C, D, E, and F. These are classified into two different operating modes, linear and switching. Class D Amplifier. Linear Mode Power Amplifiers – Class A, B, AB and class C are all linear mode amplifiers that have an output that is proportional to their input. Linear mode amplifiers do not saturate, fully turn-on or fully turn-off.
