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.

This Class D power amplifier circuit is a simple prototype and has a lot of room for improvements, My main problem with this circuit was the sampling technique, which needs to be improved. In order to reduce the clipping of the amplifier, proper inductance and capacitance values need to be calculated to get a perfect low pass filter stage.
