Op-amp saturation Because the output voltage and current of the op amp are limited, another criterion is to make sure that the op amp will not saturate with the selected inductor. An AEF is typically saturated by the output current instead of the output voltage, which is attributed to the low impedance of the injection path.Operational Amplifiers (5th Edition) -George Clayton, Steve Winder.
