Abstract:
A capacitor circuit includes a first capacitor line including a film capacitor and a second capacitor line including a ceramic capacitor that are connected in parallel with each other. The second capacitor line includes an inductance element that is connected in series with the ceramic capacitor. The inductance element is set to a value such that a series resonant frequency of the first capacitor line and a series resonant frequency of the second capacitor line are matched.
