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 ...

Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...

The circuit aims to produce a power amplifier with the use of an operational amplifier NE5534 at its input compared to classic designs which use differential amplifiers. NE5534 – a high performance ...

We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...

Circuits Integrated Hellas (CIH), a company specialising in satellite communication technology, has introduced a new family of compact Ka-band power amplifier modules that combine amplification and ...

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 ...

When I started my electrical apprenticeship, I didn’t know much about amps, outlets and electrical circuits. I had swapped out a few light fixtures and even installed a new dishwasher. But when it ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...
