Which factor is responsible for the gain of the op-amp to roll-off after a certain frequency is reached
A. Capacitive effect
B. Resistive effect
C. Inductor effect
D. None of the mentioned
Answer:A
Which factor is responsible for the gain of the op-amp to roll-off after a certain frequency is reached
A. Capacitive effect B. Resistive effect C. Inductor effect D. None of the mentioned
Explanation: The gain of the op-amp roll-off due to the presence of capacitive component, in the equivalent circuit of op-amp. The frequency increases as the reactance of the component decreases. 2. What remedy can be followed to maintain the operating frequency in the op-amps?
