WebA MOSFET works by either letting current flow across its terminals or not depending on the voltage applied. It operates on an electrical field effect produced by the voltage applied across the semiconductor surface adjacent to the metal oxide layer. As a result, this allows the MOSFET to work as either a p-type or n-type. Web14.

WebAn FET amplifier is an amplifier that uses one or more field-effect transistors (FETs). The most common type of FET amplifier is the MOSFET amplifier, which uses metal–oxide–semiconductor FETs (MOSFETs). The main advantage of a FET used for amplification is that it has very high input impedance and low output impedance . In detail … WebA MOSFET is a four-terminal device having source (S), gate (G), drain (D) and body (B) terminals. In general, The body of the MOSFET is in connection with the source terminal thus forming a three-terminal device such as a field-effect transistor. MOSFET is generally considered as a transistor and employed in both the analog and digital circuits.
