With this project, I like to build a small class D amplifier based on a 555 timer IC. I also like to use only “common” components, so this project has great educational value and is easy to build.My ...

A Zobel is an impedance matching circuit often used with loudspeakers. A Zobel circuit is also known as a Boucherot cell or somewhat incorrectly as an RC snubber. The nominal impedance of a ...

This is a single PCB 200 W Class-D Audio Power Amplifier fully designed with through hole components (external symmetrical power supply is needed). It’s been three years since we presented our Q-Watt ...

Abstract: A novel switch-mode power amplifier based on a cascade multicell multilevel circuit topology is introduced in the paper. The pulse width modulated class D power amplifier has an efficiency ...

Simple, single-channel, low-cost, high-efficiency, high-performance audio class-D power amplifier. A simple, single-channel, low-cost, high-efficiency, high-performance audio class-D power amplifier I ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

ISSCC, the International Solid-state circuits conference, is the IEEE’s annual showcase for all that is best in on-chip circuit design from across the globe. Thousands of engineers will flock there ...
