Advantages, disadvantages and application of FET over BJT
Advantages
1. FET gas high input impedance of
several mega ohms.
2. The noise produced by a FET is less
than that produced by a BJT.
3. FETs are less effect by radiation
compared to BJT.
4. FET has no offset voltage at zero
drain current and hence it forms an excellent signal chopper.
5. FETs are voltage controlled devices.
6. FETs have better thermal stability.
