Abstract
An exemplary voltage correction circuit includes a high-pass filter coupled with an integrated load, and an active clamp coupled with the high-pass filter in a closed-loop feedback arrangement. The high-pass filter includes an impedance network having a frequency response defining a lower frequency boundary of a passband of the voltage correction circuit, and the active clamp has a frequency response defining an upper frequency boundary of the passband of the voltage correction circuit. The active clamp is adapted to receive an input voltage proportional to a load transient within the passband and to generate an output current of the voltage correction circuit that cancels the effects of the load transient. A loop gain of the voltage correction circuit is greater than or equal to one within the passband and is less than one for frequencies lower than the lower frequency boundary and higher than the upper frequency boundary.
