In the FET circuit shown below:
The nature of feedback and impedance levels are given in the following statements:
(i) It is current series feedback
(ii) It is voltage series feedback
(iii) The input resistance is increased by feedback.
(iv) The output resistance is increased. The correct statements are:
-
- (i) & (ii)
- (ii) & (iii)
- (ii) & (iv)
- (ii), (iii) & (iv) (i) & (ii)
Correct Option: B
Since the voltage is feedback therefore the type of feedback is voltage feedback and since the feedback is in loop form.
Hence the circuit represents voltage-series feedback.
In voltage-series feedback input impedance after feedback, is increases and output resistance decreases.
Hence alternative (B) is the correct choice.
