MOS Field Effect Transistors (MOSFETs) topics include: The basics of MOSFET, device structure, physical and small signal operation of MOSFET, basics of MOSFET configurations and circuit biasing, body effect and discrete MOSFET circuits. Metal-oxide-semiconductor field-effect transistors (MOSFETs) are electronic devices that are used to control or amplify voltages in circuits. They are the most common type of transistor today.  MOSFETs are typically three-terminal devices with gate (G), drain (D), and source (S) terminals. They are voltage-controlled devices that use an insulated gate to... Show more
