FET
The Field-Effect Transistor(FET) is a semiconductor device which can perfom all the functions of a bipolar transistor.It operates in a fundamentally diffrent way. There are three kinds of FET avalible: the Junction Field-Effect Transistor(JFET),the Insulated Gate Field-Effect Transistor(IGFET) and the Vertical Metal Oxide Silicon power field effect transistor(VMOS). The IGFET is more often known as Metal Oxide Silicon Field-Effect Transistor(MOSFET).The MOSFET can be subdivided into two classes: the enhancement type and the depletion type. All four classes often can be obtained in either n-channel or p-channel versions so a total of eight different types of fet are avalible.  hossein amiri
