抑制同步开关噪声的超带宽电磁带隙结构研究
Research on the structure of ultra-wideband electromagnetic band gap for suppression of synchronous switch noise
摘要
Abstract
Aiming at the problem of restraining the synchronous switch noise between the power plane and the ground plane in printed circuit board,a new 2-D electromagnetic band gap(EBG)structure is proposed,which is based on etching the fold gap on the corners of the square metal patch to reduce the effective capacitance. The fold is used to increase the effective capaci-tance of the adjacent patch. The unit lattice is made up of the fold and square metal patches with gap. The simulation results indicate that compared to the Z-bridged EBG structure with the same parameters,the stop band range of BS EBG is from 220 MHz to over 20 GHz when inhibition depth is -30 dB,and the relative bandwidth is increased by about 15%,the lower-cut-off frequency is decreased by 110 MHz.关键词
