CLASS S AMPLIFIER BLOCK DIAGRAM
Power amplifier classes - Wikipedia
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.
Class D power amplifier circuit diagram, working
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. The sawtooth waveform

OverviewHistoryBasic operationTerminologySignal modulationDesign challengesA class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices 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 input into a pulse train. The audio escapes through a simple low-pass filter into the loudspeaker. The high-frequency pulses are blockeSee more on enpedia · Text under CC-BY-SA license

So before we go in advance topics, let’s start with some of the basics. Block diagram. In all practical amplifiers, a number of stages are cascaded to amplify a weak signal to a sufficient level to operate the output device. Here we are taking an example of a loudspeaker. In these, amplifiers modulate the strength of the voice.
