Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the ...

In this module on BJTs (bipolar junction transistors), we will cover the following topics: BJT Device structures, Energy band diagrams, Active bias, Leakage current, Recombination in base, Hoe ...

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.

There was no doubt about it, point-contact transistors were fidgety. The transistors being made by Bell just didn't work the same way twice, and on top of that, they were noisy. While one lab at ...
