摘要/Abstract

摘要：

为改善共面EBG（Electromagnetic BandGap）结构的SSN（Simultaneous Switching Noise）抑制性能, 通过在EBG结构单元设计中使用组合单元法, 提出一种适用于高速电路SSN抑制的共面混合桥电磁带隙（HB-EBG：Hybrid Bridges EBG）结构。实测结果表明, 在抑制深度为-40 dB时, HB-EBG结构阻带范围为225 MHz~15 GHz。与LBS（L-shaped Bridges and Slits）EBG结构相比, 在保持高频段SSN抑制性能的同时, 阻带下限截止频率由432 MHz降至225 MHz, 有效降低了带隙中心频率。信号传输特性的研究结果表明, 当采用局部拓扑并选择合适的走线策略时, 该结构在保持良好的SSN抑制性能的同时, 能实现较好的信号完整性。

Abstract:

To improve the SSN （Simultaneous Switching Noise) suppression performance of the planar EBG （Electromagnetic Band-Gap) structure, a novel pla
nar HB-BG (Hybrid Bridges EBG) is proposed by applying the concept of “united cells method” in the unit cell. In our proposed HB-BG, the -40 dB stopband is
achieved from 225 MHz to 15 GHz. The lower cutoff frequency is decreased from 432 MHz to 225 MHz as compared to the EBG structure with LBS (L-shaped Bridges and Slits). A lower band-gap center frequency is also obtained. The signal transfer characteristics of the localized HB-EBG are studied. Wideband SSN suppression and good signal integrity are successfully verified by simulations and measurements.

Key words: electromagnetic band-gap (EBG), signal integrity (SI), power integrity (PI), simultaneous switching noise (SSN), stopband
