A large percentage of LED drivers offered by many vendors use PWM (pulse-width modulation) intensity control to adjust LED brightness for a wide range of applications. In the PWM drivers, the ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

A technical paper titled “Tunnel Junction-Enabled Monolithically Integrated GaN Micro-Light Emitting Transistor” was published by researchers at the Ohio State University and Sandia National ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

Seeking to keep Moore's Law on pace, researchers have developed a repeatable technique for assembling a single-atom version of the transistor--the building block of semiconductors and computers.

Optoelectronics, the use of electronic devices for the detection and control of light, has become a preferred means for broadband and transoceanic communication networks. Below is a sneak peek at the ...

Transistors made of plastic can be controlled with great precision, according to a new article. Transistors made of plastic can be controlled with great precision, according to an article in PNAS by ...

SALT LAKE CITY – University of Utah physicists successfully controlled an electrical current using the "spin" within electrons – a step toward building an organic "spin transistor": a plastic ...

Scientists made a single-molecule transistor using quantum interference to control electron flow. This new design offers high on/off ratio and stability, potentially leading to smaller, faster, and ...
