In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

A new type of transistor structure, invented by scientists at the University of Illinois at Urbana-Champaign, has broken the 600 gigahertz speed barrier. The goal of a terahertz transistor for ...

Just as the common emitter amplifier and common base amplifier each tied those respective transistor terminals to a fixed potential and used the other two terminals as amplifier input and output, so ...

The transistor laser, invented by scientists at the University of Illinois at Urbana-Champaign, has been full of surprises. Researchers recently coaxed the device to reveal fundamental properties of ...

In 1964, when I started working in the electronics industry, a single silicon transistor cost over £1 ($2.80 at the time, or about $22 at 2014 prices). These cheap ones were not very good and higher ...

CHAMPAIGN, Ill. — A new type of transistor structure, invented by scientists at the University of Illinois at Urbana-Champaign, has broken the 600 gigahertz speed barrier. The goal of a terahertz ...
