本研究提供了一個利用週期性結構來減少訊號跨槽所產生的雜訊。平行板模態是帶線的寄生模態,它會被不連續結構激發,再和原本來自鄰近訊號線的串音雜訊疊加,使訊號完整性惡化。本論文的目標為降低平行板模態,進而提升訊號完整性。提出的想法為使用高阻抗表面來製造平行板模態的禁帶,抑制訊號跨槽產生的雜訊。
This thesis offers an application of corrugated surface with metal protrusions to suppress parallel plate mode induced by stripline crossing moat on reference plane. Parallel plate mode is the parasitic mode in stripline, excited by discontinuities or different dielectric, and so on. It would bring about another noise to adjacent traces. The total noise on quiet line is the combination of inherent crosstalk and parallel plate mode, this thesis focus on improving parallel plate mode. In order to decline pp-mode, high impedance surface is used in the circuit structure. Adding several metal protrusions on the top reference plane of stripline could make the surface impedance bigger at certain frequency bands, which means the stopband of parallel plate mode. Similarly, it could decrease the peak-to-peak value of noise in time domain. This study provides an idea about periodic structure to decline the noise from trace over moat and enhance the signal integrity on the transmission lines.
