metal–oxide–semiconductor field-effect transistor is a device
used for amplifying or switching electronic signals. In MOSFETs,
a voltage on the oxide-insulated gate electrode can induce a
conducting channel between the two other contacts called source
and drain. The channel can be of n-typeor p-type, and is
accordingly called an nMOSFET or a pMOSFET (also commonly nMOS,
pMOS). It is by far the most common transistor in both digital
and analog circuits, though the bipolar junction transistor was
at one time much more common. More information on MOSFET can be
