High Overshoot Correction Method in Voltage Regulators

This paper proposes a method of voltage overshoot correction during the load switching-off in the integrated circuits (ICs) where the negative feedback voltage regulators are used. Method uses fictive dynamic load to compensate the fast switching-off process of the actual load. The effect occurs in all regulators where the settling time of voltage regulators is larger compared with the switching time of the actual load. The proposed method gives a chance to the negative feedback regulator to keep the output voltage within a safe range and keep the thin gate low voltage transistors in safe operating mode.
