In this article, we propose a double-sided electromagnetic bandgap (DS-EBG) structure for glass interposers (GIs) with low substrate loss to suppress power/ground noise. For the first time, we validated wideband power/ground noise suppression in the GI using the proposed DS-EBG structure based on dispersion analysis and experimental verification. We experimentally verified that the proposed DS-EBG structure achieved the power/ground noise suppression (below −40 dB) between 2.5 and 8.9 GHz in the GI. Derived stopband edges, $f_{L}$ and $f_{U}$ based on the dispersion analysis, and 3-D electromagnetic (EM) simulation showed a good correlation with measurements. The effectiveness of the proposed DS-EBG structure on the power/ground noise suppression is verified by analyzing noise propagation in the power distribution network and coupling to the GI channel. Using the 3-D EM simulation, we verified that the proposed DS-EBG structure suppressed the power/ground noise coupling and improved the eye diagram of the GI channel. Finally, we propose a design methodology to broaden the isolation bandgap or miniaturize the dimensions based on the dispersion analysis.

使用双面电磁带隙结构的低损耗玻璃中介层中的宽带电源/地噪声抑制

在本文中，我们提出了一种用于玻璃中介层 (GI) 的双面电磁带隙 (DS-EBG) 结构，其具有低基板损耗以抑制电源/接地噪声。我们首次使用基于色散分析和实验验证的 DS-EBG 结构验证了 GI 中的宽带电源/地噪声抑制。我们通过实验验证了所提出的 DS-EBG 结构在 GI 中的 2.5 和 8.9 GHz 之间实现了电源/地噪声抑制（低于 -40 dB）。导出的阻带边缘， $f_{L}$ 和 $f_{U}$ 基于色散分析和 3-D 电磁 (EM) 模拟显示出与测量值的良好相关性。通过分析配电网络中的噪声传播和耦合到 GI 通道，验证了所提出的 DS-EBG 结构对电源/地噪声抑制的有效性。使用 3-D EM 仿真，我们验证了所提出的 DS-EBG 结构抑制了电源/地噪声耦合并改进了 GI 通道的眼图。最后，我们提出了一种基于色散分析来扩大隔离带隙或缩小尺寸的设计方法。
