Thus the three basic bipolar transistor circuit configurations ... There are equivalent P-channel devices, just as there are PNP and NPN bipolar transistors. Were you to bias an n-channel JFET ...

You might not be familiar with how a FET works, how to use one and what are the caveats – let’s go through the basics ... you can add a NPN transistor section as shown – this inverts ...

The image below shows the cross-section of a basic NPN transistor, complete with labeled terminals. When a transistor operates in this manner,it is said to be in an active state. Bipolar transistors ...

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 are several basic types of RF transistors: Bipolar RF transistors: Consist of an N-type or P-type layer sandwiched between two layers of the opposite type. Both NPN and PNP configurations are ...
