A load switch is an electronic switch. It works like a relay to power supply rails in systems, but it has no moving parts. Load switches are increasingly found in today’s portable electronic devices, ...

Constructing a MOSFET switch is one of the basic level electronics projects and could be useful for beginners to get a hang of the various FET transistors. Read through the article to know more on ...

A little over a year ago, I had a project that required driving an RF single-pole double-throw (SPDT) coaxial switch either by transistor-transistor-logic (TTL) pulses sent by an external source or by ...

A simple circuit is a chain of different parts with wires and switches which allows electricity to flow around. All electrical appliances use circuits. For electricity to flow correctly, the circuit ...

This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be a way ...
