Quantification of EMI for power-ground plane and novel EBG structure for SSN suppression

Abstract

The partial element equivalent circuit (PEEC) method and the field equivalence principle are coupled by edge node voltage to quantify the radiation emission of a power/ground plane pair in this paper. Simulation results using the proposed method show a good agreement with the measurement. Meanwhile, in order to suppress the propagation of simultaneous switching noise (SSN) that leads to radiation in packaging, a novel electromagnetic bandgap (EBG) structure is proposed in this paper and it can achieve ultrawideband suppression of SSN.
