Hybrid analytical modeling of noise coupling to signal traces in a power bus with embedded film capacitor

Abstract

An accurate hybrid analytical method is proposed to determine the coupling of switching noise to signal traces in a multilayer power bus with embedded film capacitor. We used the induction equivalent theorem to derive the solution of noise coupling and the segmentation method to calculate the electric field of the noise in a power bus. The proposed method was verified by measurements of impedance parameters in the frequency domain.
