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. P-FETs are like PNP transistors, too – the ...

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 ...
