Chapter 29. field effect transistor

discrete semiconductor > multi-junction > field effect transistor

The term field-effect transistor encompasses a family primarily consisting of the junction field-effect transistor (or JFET, which is the simplest generic type) and the metal-oxide semiconductor field-effect transistor (or MOSFET, also sometimes known as an insulated-gate field-effect transistor, or IGFET). Because the principles of operation overlap considerably, the entire -FET family is grouped in this entry.
