Abstract

A multiple resonant frequency decoupling capacitor is presented. The decoupling capacitor comprises a plurality of capacitive elements, each having a different resonant frequency to define a frequency bandwidth for noise supression. One of the capacitive elements having a resonant frequency indicative of the clock frequency of an integrated circuit being decoupled by the capacitor. Further, at least one other capacitive element having a resonant frequecny indicative of a harmonic frequency of the clock frequency.
