== Amplifier ==
FET as an amplifier.
==Advantages of FET==
* The main advantage is its high input resistance in the order of 100M ohms.
Thus, FET is a voltage-controlled device.
It shows a high degree of isolation between input and output.
* FET is a unipolar device, depending only upon majority current flow.
* FET is less noisy and is thus found in FM tuners for quiet reception.
==Disadvantages of FET==
* It has relatively low gain-bandwidth product.
* MOSFET has a drawback of being very susceptible to overload voltages,thus requiring special handling during installation.
