摘要 该文根据电磁带隙结构的带隙形成机理及共面电磁带隙结构等效电路分析模型,通过引入新型的C-型桥接连线及开槽设计,提出了一种适用于高速电路同步开关噪声(SSN)抑制的带有狭缝的共面C-型桥电磁带隙(CBS-EBG)结构。实测结果表明,在抑制深度为-40 d B时,阻带范围为296 MHz^15 GHz,与LBS-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下降至296 MHz,有效降低了带隙中心频率。研究了局部拓扑下的信号传输特性,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,能够实现较好的信号完整性。 According to the physical mechanism and the equivalent circuit model of the planar Electromagnetic Band-Gap (EBG) structure, a novel planar EBG structure named CBS-EBG for Simultaneous Switching Noise (SSN) suppression in high-speed circuits is proposed by introducing the special C-shaped Bridges and Slits (CBS). Real-data experiment shows that -40 dB stopband is realized from 296 MHz-15 GHz. Compared with the LBS-EBG structure, the lower cutoff frequency decreases from 432 MHz to 296 MHz with a similar higher frequency range performance, and a lower band-gap center frequency is realized. The transfer characteristic of the signal under localized CBS-EBG is studied. Simulation and measurement are performed to verify the high performance of the proposed CBS-EBG both in SSN suppression and signal integrity with the local topology and appropriate routing policy.
