This circuit is called a high-side switch – it enables you ... we typically just refer to them as NPN or PNP transistors. These are all under the transistor umbrella, but when people say ...

The NPN transistor is considered, but results obtained are germane to analysis of the PNP transistor as well ... was challenged by Bell management to invent a solid-state switch to replace mechanical ...

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.

Transistors are small, versatile semiconductor devices designed to switch or amplify electronic signals and ... The negative and positive connections made by a PNP transistor are also the reverse of ...
