| 随着数字电路的噪声容限和时序容限不断减小，电源地平面上的同步开关噪声（SSN）成
为高速设计的主要瓶颈之一。而现有抑制SSN的方法存在各自的不足，因而提出采用电磁带

构(EBG)设计来抑制SSN，软件仿真证明该方法是有效的。基于对多种不同结构
EBG的研究，给出了EBG的设计思路和最新发展趋势，为今后的实际应用研究提供一定的参考
与指导。 |

| Abstract: |
| With the reduction of noise margin and timing margin in the digital circuit, sim
ultaneous switching noise (SSN) has become the bottleneck of the high speed desi
gn on the power plane,but existing SSN suppression methods have their shortcomin
gs. In this paper electromagnetic band gap (EBG) is adopted to restrain SSN,
its effectiveness is proved through simulation and the design methodology
and latest development tendency of EBG are presented in hope of providing some
references for future practical study. |
