Abstract :
Aim of this paper is to describe the simultaneous switching noise (SSN) mitigation by means of a novel electromagnetic band gap (EBG) structure with double L metal patches and two connected branches. The proposed EBG achieves -40 dB of stop band over two distinctive frequencies range: 1 GHz - 4.3 GHz and 5.8 GHz - 8 GHz respectively. The impact of the proposed design on the signal integrity of a single-ended trace passing from the top layer to the bottom layer by means of two via transition is investigated in time domain by calculating eye-diagrams and time domain reflectometry (TDR). A partial EBG model is finally proposed to provide a better performance in term of signal quality while keeping the noise suppression level of the full EBG model.
