Question

Common drain amplifier is an example of

• A. Current series feedback
• B. Voltage shunt feedback
• C. ​​​​​​Voltage series feedback
• D. Current shunt feedback

Answer 1

The correct option is C ​​​​​​Voltage series feedback

Ans : (a)

The common drain or source follower circuit is able to provide a very high input impedance and low output impedance and is used to act as a buffer amplifier. As per the input and output impedance we can sample the output voltage and feed to input in series with input voltage .This determines there is Voltage seires feedback .
