This Design Idea is a two-wire current regulator that strikes a good balance between performance and parts count. Employing three transistors, three resistors, and one LED, it achieves good regulation ...

I was at Burr-Brown in 1988 and I knew Mark Stitt well. He was a mentor to me and I was devastated at his untimely death. He had written an amazing Burr-Brown Current Source app note 1 that I have ...

As the industry advances into the angstrom era, gate-all-around architectures combined with atomic-scale materials ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

Download this article in PDF format. When you connect the gate to the source of a JFET (junction field-effect transistor), it becomes a two-terminal current source. The current that will flow is ...

The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few ...

Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...

At the December 2021 IEDM conference (a conference for people who design advanced semiconductors), IBM announced it was turning transistors on their heads to keep Moore’s Law scaling alive. The new ...

Researchers built a four-atom-thick transistor combining an atomically thin semiconductor and molecular crystal. It uses ...
