How does the gain of an ideal operational amplifier vary with frequency?

  1. It increases linearly with increasing frequency
  2. It decreases linearly with increasing frequency
  3. It decreases logarithmically with increasing frequency
  4. It does not vary with frequencyالإجابة الصحيحة

الشرح

The ideal op-amp model assumes infinite gain at all frequencies, so by definition gain does not change with frequency. Real devices depart from this because internal compensation rolls the open-loop gain off above a low corner frequency.
