Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

The transistor and the PWM-switch, the core circuit of power converters, have interesting analogs. Both have three terminals, hence three configurations. They are active devices, and each has a key ...

Fujitsu Laboratories Limited and Fujitsu Microelectronics Limited today announced the development of a CMOS logic (1) process-based high-voltage transistor featuring high breakdown voltage, suitable ...

This project demonstrates how to build a simple latching power switch circuit using an NPN transistor and a pushbutton, powered by a 9V battery. When the pushbutton is pressed, the transistor ...

The use of transistors for switching things ON and OFF is a key feature of proper hacking. The ability for bipolar transistors to turn things ON and OFF is one of the less known uses while transistors ...

A monolithic GaN mains power converter IC was the target of Leibniz University Hannover, which worked with Texas Instruments. And the result is a 15W off-line PSU that can feed a 30-60V LED string ...

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team developed a thickness-controlled black phosphorous tunnel ...

Scientists built a nano switch that controls excitons, chargeless quantum quasiparticles, at room temperature.
