PROBLEM TO BE SOLVED: To provide a system and a method for reducing a voltage fluctuation such as the undershoot and/or overshoot of a supply voltage in an integrated circuit chip or the like. SOLUTION: According to one embodiment, a delay system 14 supplies the delaying section of a first reference signal in response to the supply voltage. A comparator 16 supplies a control signal controlling a protective device 18 on the basis of the delaying section of the first reference signal and a second reference signal. A voltage threshold is determined by the quantity of a delay supplied by the delay system, and the comparator supplies the control signal on the basis of the voltage threshold value.
