==Advantages of FET==

* The main advantage is its high input resistance in the order of 100M ohms.

Thus, FETit is a voltage-controlled device.

It shows a high degree of isolation between input and output.

* FETIt is a unipolar device, depending only upon majority current flow.

* FETIt is less noisy and is thus found in FM tuners for quiet reception.

* It is relatively immune to radiation.

* It exhibits no offset voltage at zero drain current and hence makes an excellent signal chopper.

* It has thermal stability.
