There are equivalent P-channel devices, just as there are PNP and NPN bipolar transistors. Were you to bias an n-channel JFET as you would a bipolar transistor with a positive bias on its gate ...

Just like with NPN and PNP transistors, there are N-FETs and P-FETs. N-FETs are like NPN transistors – the gate pin needs to have higher voltage than the source pin for the FET to open.

An integrated circuit (IC) technique developed by Fairchild Instruments in 1959 that creates transistors on a flat surface compared to the uneven surface of the earlier mesa process. The planar ...
