<p>The present invention has: a user circuit having a plurality of circuit modules each containing an availability ratio control circuit; and a power source noise suppression circuit that determines the amount of current fluctuation in the user circuit by monitoring the availability ratio of the plurality of circuit modules, and in accordance with the results of determining the amount of current fluctuation, controls, via each availability ratio control circuit, the availability ratio of the corresponding circuit module. Control is performed in a manner so that the current fluctuation cycle in the amount of current fluctuation is offset from the resonance frequency band of the power supply system.</p> |
