Semiconductor Electronics Materials Devices And Simple Circuits Ques 83
83. The voltage gain of an amplifier with $9 \%$ negative feedback is $10$ . The voltage gain without feedback will be
[2008]
(a) $90$
(b) $10$
(c) $1.25$
(d) $100$
Show Answer
Answer:
Correct Answer: 83.(d)
Solution:
- (d) Negative feedback is applied to reduce the output voltage of an amplifier. If there is no negative feedback, the value of output voltage could be very high. In the options given, the maximum value of voltage gain is $100$ . Hence it is the correct option.
