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 ...

According to the U.S. Department of Energy, the electricity used to light businesses represents 25% of the energy they spend, so it's important to develop energy-saving devices. Now engineers at the ...

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 ...
