隨著科技的進步，IC時脈的提高，進而衍生出信號完整性(SI)和電源完整性(PI)等問題。本論文研究是利用開路殘段(open stub)結構，有效增強PI/SI的性能，分別在被動等化器和混合式電磁能間隙(EBG)結構上，加入開路殘段，藉由適當的設計，進一步提升兩者特性。增強式被動等化器，主要是利用開路殘段之電容性及電感性，在適當頻率下提供補償的效果，使頻率響應表現更為平坦，比起傳統被動等化器，它有更好的信號傳輸質量，此外，利用電鍍製程所殘留下來的電鍍線(Plating bars)設計此開路殘段，不僅可提升傳輸質量，更不會增加額外空間；混合式超寬頻EBG結構，主要是利用開路殘段所產生止帶，抑制特定頻率之雜訊，使止帶頻寬增加，此結構不僅擁有一般混合式EBG結構，在低頻部分的好表現，更有著超寬頻抑制的效果，此外，也對針對EBG結構所為人詬病的信號完整性問題，提出一＂接地線＂結構，有效改善單端傳輸線的信號傳輸質量。

With the advance of IC manufacture process, operating speed of the circuit systems gets higher, so does the demand for data communication. This phenomenon will induce the problem of signal integrity (SI) and power integrity (PI). Therefore, the purpose of this thesis is using open-stub structure to enhance the effective of signal and power integrity. The enhanced passive equalizer is using the frequency-dependent property of open stubs, so that makes the high-frequency part get a larger inductive to increase the equalizer performance. Compared the conventional passive equalizer with the proposed structure, a good performance has been demonstrated. In addition, by using plating bars to design the open-stub, it promote transmission quality and do not increase extra space. The ultra-wideban hybrid EBG structure, is using the stop band which caused by the opeb-stub to suppress certain frequency’s noise and increase the stop bandwidth. This structure not only has advantage of the hybrid EBG structure, but also has effect of ultra-wideband suppress. Moreover, we alse proposed the ground trace structure to solve the problem of Signal Integrity, and improve the signal quality of single-ended transmission line.
