Question

9. The maximum voltage gain of an op-amp is 100,000. The voltage gain at the cut-off frequency is:
a) None are correct
b) 97 dB
c) 50 dB
d) 100 dB

Answer 1

a) None are correct - The maximum voltage gain of an op-amp is a measure of its open-loop gain, which is the gain when no feedback is applied. The cut-off frequency refers to the frequency at which the gain of the op-amp begins to decrease. However, the question does not provide any information about the specific cut-off frequency being referred to, so it is not possible to calculate the voltage gain at that frequency.
