This paper presents a new analytical model to suppress RLC
resonance effects in power/ground lines due to a decoupling
capacitor. First, the resonance frequency of an RLC circuit
which is composed of package inductance, decoupling
capacitor, and output drivers is accurately estimated. Next,
using the estimated resonance frequency, a suitable decoupling
capacitor size is determined. Then, a novel design methodology
to suppress the resonance effects is developed. Finally, its
validity is shown by using 0.18 µm process-based-HSPICE
simulation.
