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 ...

These are all under the transistor umbrella, but when people say “transistor”, they usually mean BJT, and when people say “FET”, they usually mean “MOSFET”. You can imagine a FET as a ...

That said, the FET is a fascinating device. Join us as we take an in-depth look at their operation, and how and where you might use one. A diagram of an n-channel JFET. As the negative gate ...
