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. WebMOSFETs are of two classes: Enhancement mode and depletion mode. Each class is available as n-channel or p-channel; hence overall they tally up to four types of …
