Question

describe mosfet and its features
​

Answer 1

Answer:

MOSFETs are tri-terminal, unipolar, voltage-controlled, high input impedance devices which form an integral part of vast variety of electronic circuits. Cut-off region is a region in which the MOSFET will be OFF as there will be no current flow through it.

Answer 2

MOSFET stands for Metal Oxide Silicon Field Effect Transistor or Metal Oxide Semiconductor Field Effect Transistor. This is also called as IGFET meaning Insulated Gate Field Effect Transistor. The FET is operated in both depletion and enhancement modes of operation.

In general, the MOSFET works as a switch, the MOSFET controls the voltage and current flow between the source and drain. The working of the MOSFET depends on the MOS capacitor, which is the semiconductor surface below the oxide layers between the source and drain terminal

FEATURES OF A GOOD MOSFET :-

A good MOSFET should have a reading of 0.4V to 0.9V (depends on the MOSFET type). If the reading is zero, the MOSFET is defective. When the reading is “open” or no reading, the MOSFET is also defective. When you reverse the DMM probe connections, the reading should be “open” or no reading for a good MOSFET.
