A generic circuit diagram of a Class B amplifier using FET control devices is shown in Figure 1. Figure 1 AClass B amplifier using FET control devices Many years ago in engineering school, we learned ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

Editor's note: This multi-part article is an expanded version of the article by the same title published in the EE Times print edition. Figure 2: Class D open-loop-amplifier block diagram. Since most ...

In market for a powerful 200 WPC amp? ATI has you covered with two completely different technologies. We compare the AT4000 class A/B and the AT522NC Class-D amplifiers to help you decide. EIA 1kHz ...

We often take wireless communications for granted, without considering the underlying complexity and technological barriers. It's worth taking a closer look at those aspects. Pulse width modulation ...

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 ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...
