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 ...

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 ...

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 ...

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 ...

At the heart of modern electronics are transistors, which act like valves to direct the flow of electrons. Now researchers at the University of California at Berkeley have created the first ...

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 ...

From smartphones to supercomputers, electronics have a heat problem. Modern computer chips suffer from microscopic “hotspots” with power density levels that exceed those of rocket nozzles and even ...
