MOSFET (Field Effect Transistor) is a transistor whose conductivity is controlled by a lateral electric field. Its main types include: Enhancement type: conducts when the gate voltage is higher than the threshold voltage. Depletion mode: conducts when the gate voltage is zero. MOSFETs are widely used in power control, analog/digital circuits, amplifiers, oscillators, microprocessors and memories.

MOSFET: a type of field effect transistor

MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a type of A field-effect transistor (FET) whose conductivity is controlled by a lateral electric field.

Principle of MOSFET

MOSFET consists of three layers of semiconductor materials, namely source, drain and a semiconductor layer called the body. There is a thin insulating layer between the source and drain called the gate oxide.

When a voltage is applied to the gate, it creates an electric field in the body. This electric field changes the conductivity of the body, allowing current to flow between the source and drain. By varying the gate voltage, the degree to which the MOSFET conducts can be controlled.

Types of MOSFET

There are two main types of MOSFET:

  • Enhancement-mode MOSFET:When the gate It is turned on when the pole voltage is higher than the threshold voltage.
  • Depletion mode MOSFET: Will conduct even if the gate voltage is zero.

Applications of MOSFETs

MOSFETs are widely used in a variety of electronic devices, including:

  • Power controls and switches
  • Analog and Digital Circuits
  • Amplifiers and Oscillators
  • Microprocessors and Memory
