What are the advantages and disadvantages of MOSFET?

Answer 1

Advantages:-

1- mosfet are small compare to bjt's so it fabricated easily and space saving scheme on the ic's

2- mosfet's input impedance are very high so they do not load the circuits. loading effect doesn't arise.

3- operating frequency is very high so may be used at higher frequencies.

4- used in digital circuits for it's reliability.

5- effect of noise is less than bjt. so high signal to noise ratio.

6-mosfets are unipolar devices so reverse saturation current doesn't exist.

7- it consume less D.C power rather than BJT.

Disadvantages:-

handling is not easy-

Mosfet is very sensitive to electrostatic charge so it may be destroy when you touch the pins of a mosfet devices by hand.

trans conductance is low than BJT.
