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 ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

The TDA7294 IC is a popular sound amplifier IC with low cost that has a ton of power handling capacity, 100W to be exact. For this tutorial, we are going to use two of those TDA7294 ICs in a bridge ...

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 ...

Abstract: This tutorial presents an overview of RF and mm-wave power-amplifier (PA) designs in silicon, focusing on the design fundamentals. First, the tutorial introduces PA performance metrics and ...

Devialet, the French company at the intersection of audio engineering and luxury, is known for its egg-shaped Phantom speakers, but the company’s first product was in fact an audio amplifier that you ...
