Class D Audio Amplifiers: What, Why, and How

Class D amplif iers, f irst proposed in 1958, have become increasingly popular in recent years. What are Class D amplifiers? How do they compare with other kinds of amplifiers? Why is Class D of interest for audio? What... »

A Little Theory of Class-D Amplifiers

A Little Theory of Class-D Amplifiers

Why Class-D? It is a known fact that Class-A or Class-AB amplifiers are rather inefficient and thereforeproduces rather little power for the buck. When it comes to subwoofers, and electrical low frequency enhanced subwoofers in particular, the requirement for high... »

Class D Fundamentals of Operation

Class D Amplifiers: Fundamentals of Operation Introduction Most audio system design engineers are well aware of the power-efficiency advantages of Class D amplifiers over linear audio-amplifier classes such as Class A, B, and AB. In linear amplifiers such as Class AB,... »

Theory Class D Amplifier

Theory Class D Amplifier

A Class D amplifier or switching amplifier is an electronic amplifier where all power devices (usually MOSFETs) are operated as binary switches. They are either fully on or fully off. Ideally, zero time is spent transitioning between those two states.... »
