This experimental (3) transistor class A audio power amplifier delivers 25mW into an 8Ω load, or 50mW into a 4Ω load using only a 1.5V power source. At such low voltages, there are many issues to ...

Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Audio amplifier products are becoming more and more advanced in ...

This is an excerpt from “Self on Audio,” by Douglas Self, used with permission from Newnes Publishers, a division of Elsevier. For many years I felt that the output stages of power amplifiers ...

The first step in designing a microwave frequency power amplifier monolithic microwave integrated circuit on a given GaN foundry process is to select the transistor size and bias, writes Liam Devlin.
