What is MOSFET

MOS is the abbreviation of MOSFET. MOSFET metal oxide semiconductor field effect transistor (MOSFET) is called Metal Oxide Semiconductor Field Effect Transistor (MOSFET) for short.

Generally, it is metal oxide semiconductor field effect transistor, or metal insulator semiconductor. G: Gate gate; S: Source; D: Drain drain. The source and drain of MOS transistor can be switched, and they are both N-type regions formed in the P-type background. In most cases, the two regions are the same, and even if the two ends are switched, the device performance will not be affected. Such devices are considered symmetrical.

FETs are divided into PMOS (P channel type) and NMOS (N channel type), which belong to insulated gate FETs
