All these components are built on a base of the semiconducting ... What does "NPN" or "PNP" mean in terms of a transistor? "NPN" and "PNP" refer to the arrangement of the different types of ...

William Shockley improved on this design with his junction transistor, a three-layer sandwich of different types of semiconductor. The diagram illustrates the basic design of an NPN junction ...

[William Fraser], however, has come up with a design using just three components ... hooked up to a 2N3904 NPN transistor and an 85-turn coil. It won’t start oscillating on its own, but when ...

Fairchild uses npn transistors in DCTL configuration [for ... just can’t take a circuit breadboarded with conventional components and use the same design in diffused silicon microcircuitry ...

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

Bipolar transistors are available as individually packaged discrete components as well as by the hundreds of thousands on a single chip. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other ...
