the basics of class d amplifiers while there are a variety of modulator topologies used in modern class d amplifiers the most basic topology utilizes pulse width modulation pwm with a triangle wave or sawtooth oscillator figure 1 shows a simplified block diagram of a pwm based half bridge class d amplifier.

class d amplifier wikipedia.

01 03 2006 oscilloscope pictures from typical class d amplifiers see below shows a near sine wave which is the attenuated fundamental of the switching frequency with short bursts of hf near the zero crossings these bursts occur when the power stage switches from one state to the other.

class d audio amplifiers what why and how analog devices.

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 input into a pulse train.
