Advantages of Mos diode

1. It can be applied for magnification. Due to the high input impedance of FET amplifiers, the capacity of coupling capacitors can be very small, so electrolytic capacitors are not required.

2. High input impedance is very suitable for impedance transformation. It is commonly used for impedance transformation in the input stage of multi-stage amplifiers.

3. It can be used as a variable resistor.

4. It can be conveniently used as a constant current source.

5. It can be used as an electronic switch.

6. Great flexibility in circuit design. The gate bias can be positive, negative, or zero. A transistor can only operate under positive bias, while an electron diode can only operate under negative bias. In addition, high input impedance can reduce the load on the signal source and make it easy to match with the previous stage.
