The circuit below shows a 4-transistor utility amplifier suitable for a variety of projects including receivers, intercoms, microphones, telephone pick-up coils, and general audio monitoring. The ...

This compact mains voltage sensor is intended to monitor and signal to another circuit, for instance a microcontroller, about the presence and/or absence of the ac mains voltage. For this task, a ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

Teledyne e2v HiRel has introduced pair of isolated 650V 4A gate drivers aimed at GaN power transistors, offering 2.5kVrms isolation and 100% ac-dc testing at -55 to 125°C. TDGD271 is a single channel ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

Field-effect transistors based on carbon nanotubes have been shown to be faster and less energy consuming than their silicon counterparts. However, ensuring these advantages are maintained for ...
