摘要:

提出一种新型超宽带电磁带隙结构,以抑制印刷电路板(PCB)上的同步开关噪声. 基于电磁带隙结构的理论分析和设计,对新型电磁带隙结构的阻带特性及信号完整性进行了仿真分析. 仿真结果表明, 与相同参数的Z型桥电磁带隙结构比较,新型电磁带隙结构的阻带带宽提高,下截止频率降低;同时使用差分线对传输信号时,新型电磁带隙结构电源平面保持了较好的信号完整性.

关键词: 同步开关噪声, 电磁带隙, 信号完整性, 电磁兼容性

Abstract:

A new ultra-wideband electromagnetic bandgap (EBG) structure is proposed for simultaneous switching noise suppression (SSN). A analysis and design of the bandgap properties of the new EBG structure is given, the characteristics of stopband and signal integrity are simulated, showing that the new EBG's stopband is improved, and the lower cut-off frequency is decreased comparing with the Z-bridged EBG structure with the same parameters. Meanwhile, signal integrity of the proposed EBG power plane can be improved by using differential transmission lines.

Key words: simultaneous switching noise; electromagnetic bandgap; signal integrity, electromagnetic compatibility
