Metal-Oxide Semiconductor Field-Effect Transistor (MOSFET)

BJTs were studied in the previous chapter. Metal-oxide semiconductor field-effect transistor (MOSFET) (Figures 8-1 and 8-2) is another important type of transistor that is used in electronic circuits. MOSFETs are electronic devices used to switch or amplify voltages in circuits. It is a voltage controlled device and is constructed by three terminals. The terminals of MOSFET are named as follows: gate, drain, and source. This chapter studies the MOSFETs.
