Metal Oxide Silicon Field Effect Transistors (MOSFET)

F1 Engineering Savita 5-4-23 D2

  • It is a voltage-controlled three-terminal device that is used for switching and amplification purposes.
  • The terminals are the drain, gate, and source.
  • MOSFETs are of two classes: Enhancement mode and depletion mode. Each class is available as an n-channel or p-channel.
  • The voltage at the gate controls the operation of the MOSFET. In this case, both positive and negative voltages can be applied to the gate as it is insulated from the channel.
  • With a negative gate bias voltage, it acts as a depletion MOSFET while with a positive gate bias voltage, it acts as an Enhancement MOSFET.
  • MOSFET has high input resistance and low output resistance in common drain configurations.
