ABSTRACT:
A device for inhibiting power supply voltage fluctuation that is caused by fluctuation of a load current generated by a load circuit. The device includes a current consumption circuit, a data generation circuit, and a D/A converter. The current consumption circuit is connected to a power supply and the load circuit to generate a consumption current that flows parallel to the load current of the load circuit. The data generation circuit controls the consumption current of the current consumption circuit in order to inhibit fluctuation of an output current of the power supply, which is the sum of the load current and the consumption current, when the load current rises and when the consumption current falls. The D/A converter converts the digital signal to an analog signal and provides the analog signal to the current consumption circuit.
