How does the gain of an ideal operational amplifier vary with frequency?
- A.It increases linearly with increasing frequency
- B.It decreases linearly with increasing frequency
- C.It decreases logarithmically with increasing frequency
- D.It does not vary with frequency (correct answer)
WhyAn ideal operational amplifier's gain does not vary with frequency. An ideal operational amplifier is defined as having infinite, frequency-independent open-loop gain, so by definition its gain doesn't vary with frequency at all, a simplifying assumption used for basic op-amp circuit analysis even though real op-amps do roll off at high frequency, answer D. Gain increasing or decreasing, linearly or logarithmically, with frequency describes real-world op-amp behavior, not the idealized model this question is specifically asking about.
