“…This resonance peak may induce a serious problem for high-speed digital devices. To reduce the resonance peaks in the low-frequency ranges, combining a PDN with a decoupling capacitor can be considered [30][31][32][33]. However, an interaction between the decoupling capacitor and the PDN impedance can generate an additional resonance peak or just shift its frequency.…”

In this paper, we present the power integrity analysis of a power distribution network (PDN) employing a segmentation technique based on the electromagnetic bandgap (EBG) structure with a defected ground structure (DGS). For efficient analysis of power integrity, a domain decomposition method (DDM) with a novel modeling of the DGS–EBG-based PDN is presented. In the DDM, analytical models for the partitioned parts of the PDN are developed, and their impedance parameters are analytically extracted. The resonant modes for the power integrity analysis are rigorously examined using the DDM and electric-field distribution. The effect of the DGS–EBG stopband on the resonant modes are analyzed. The proposed DDM and power integrity analysis are verified using full-wave simulation and measurements. The DDM result shows good agreement with the full-wave simulation and measurements.
