The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...

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 ...

A single electron makes the difference between "on" and "off" for a new transistor made from a single carbon nanotube, whose minute size and low-energy requirements should make it an ideal device for ...

Modern circuit design is a “mixed signal” endeavor thanks to the availability of sophisticated process technologies that make available bipolar and CMOS (Complementary Metal Oxide Semiconductor), ...

The holiday gave me a chance to play with bipolar transistor mosfet drivers again. And things did not go quite as planned. I had been using the circuit on the right quite happily from a signal ...

A study by an engineering team from the University of Illinois has found that light and electrons can work together in transistor lasers to produce faster switching speeds than in any other device.

A single electron makes the difference between “on” and “off” for a new transistor made from a single carbon nanotube, whose minute size and low-energy requirements should make it an ideal device for ...
