Abstract
A method for configuring a bypass capacitor for use in conjunction with an integrated circuit device is disclosed. In an exemplary embodiment of the invention, the method includes selecting mechanical dimensions for the bypass capacitor, the mechanical dimensions causing the bypass capacitor to exhibit electrical losses at a clock frequency of the integrated circuit device. The bypass capacitor preferably includes a ferroelectric dielectric material. In addition, the selection of mechanical dimensions for the bypass capacitor determines a mechanical resonance frequency for the bypass capacitor, with the mechanical resonance frequency corresponding to the clock frequency.
