In the AC equivalent circuit shown in Fig, if Iin is the Input current and Feedback Resistance is very large, the type of Feedback
A. Voltage – Voltage Feedback I<sub>in</sub>
B. Voltage – Current Feedback
C. Current – Current Feedback
D. Current – Voltage Feedback
Please scroll down to see the correct answer and solution guide.
Right Answer is: B
SOLUTION
Procedure to identify the type of Feedback:
(1) Identify the element responsible for the Feedback.
(2) If Feedback element is directly connected to the output node, it indicates voltage sampling otherwise it indicates current sampling.
(3) If Feedback element is directly connected to the Input node it indicates shunt Mixing otherwise it indicate series mixing.
∴ It is voltage current Feedback.
