Feedback is an ubiquitous and unavoidable basic technique that keeps the world running. It is only controversial in consumer audio, and then only specifically in power amplifiers. This dates from ...

Until now we have been speaking about the linear distortions of the amplifiers. A linear distortion involves a change in the waveshape, or the frequency response, but where no new frequencies are ...

The Class D amplifier has some added challenges. Real world transistor switching characteristics require that some degree of dead-time is present in each modulation cycle to control the ...
