When the germanium heated up -- a natural outcome of being part of an electrical circuit -- the transistor would have too many free electrons. Since a transistor only works because it has a ...

On the other hand, checking with the datasheet for the pinout will eliminate this problem, and when drawing the schematic, the FET symbol ... driving circuit – it has an NPN transistor, but ...

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.

In this module on MOSFETs (metal-oxide-semiconductor field-effect transistors), we cover the following topics: History of the development of MOSFETs, Device structure, Device types, Circuit symbols, ...
