This document is an application note of the Printed Circuit Board (PCB) layout techniques in operational amplifier precision design. It discusses the PCB effects experienced in high DC precision op ...

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 ...

What if a palm-sized amp could outperform larger, more expensive modules while delivering serious sound quality? Check out ...

Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

I have a Cadence Z800 car audio amplifier that has a cracked PCB. I got into an accident last winter and when I was hit, it caused the body of the amplifier to shift to the side about an inch, ...

Of digital electronics, a wise man once said that “Every idiot can count to one.” Truer words have rarely been spoken, because at the end of the day, every digital circuit is really just an analog ...
