Technology has democratized the music industry in many obvious ways – notice how every band, regardless of stature, has a MySpace page? But one of technology's more subtle effects has been to make our ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

Class D amps from $130 to $50,000—pulling more ears into hi-fi without demanding you sell a kidney. Solid tech, serious power, and none of the usual overpriced fluff. Finally, affordable doesn’t sound ...

Firstly I'd like to point out that "digital amps" is a misnomer. There are two categories: Analog-controlled class D. Switching amplifiers with an analog input signal ...

For driving an antenna, efficient generation of a clean and stable signal is required for optimum performance of many systems. This paper focuses on methodologies to efficiently apply a pure, ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

Class D amps are simple – just take an input, and use that to modulate a square wave with PWM. Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence.

A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

This article was originally published in the Dec 14, 1998 issue of Electronic Design. Class-D audio power amplifiers (APAs) were first introduced nearly 50 years ago. Since then, they have been used ...
