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 ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

The 2026 National Electrical Code clarifies rules for 10 amp branch circuits, conductor sizes and permitted uses for LED lighting applications.

Here, a power amplifier circuit has been designed using MOSFET to produce 100 W output to drive a load of about 8 Ω. Here, a power amplifier circuit has been designed using MOSFET to produce 100 W ...

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., ...

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 ...

Wesgarde is highlighting the Optifuse 641, 642 and 643 mid-amp circuit breakers for large vehicle applications, offering ...

Onkyo is unveiling two new network streamers and Integrated amplifiers at CES 2026. The Muse Series combine the brand’s ...
