Traditionally, tube power amps were all point-to-point (PTP) wired or of stripboard construction. Components were wired to a long tag board, which was then mounted under a metal chassis. From the tag ...

In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

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 ...

A Thermocouple is a terrific way to measure temperature. The effects of temperature change on dissimilar metals produces a measurable voltage. But to make that measurement you need an amplifier ...

Addressing the core issues of latency and integration in developing audio amplifiers for today’s smart cockpits.

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, ...

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

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 ...
