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 ...

Transistors provide this isolation ... B1b). Absence of critical biasing. We do not want to have to set the operating point of each device to a high level of precision. A device with the input ...

In this module on MOSFETs (metal-oxide-semiconductor field-effect transistors), we cover the following topics: History of the development of MOSFETs, Device structure, Device types, Circuit symbols, ...
