Using the concept of cascading EBG structures with the different stop-band frequencies and band-edge estimation, the coupling noise between isolation islands can be significantly reduced. A compact size can also be achieved by spiral EBG structures with increasing number of turns to save the occupied area. For the ease and accuracy in the design of EBG structures, the modified inductance formula, the design diagram of spiral EBG structures, and the effective occupied area of EBG structures are also presented. A systematic design procedure is established and based on which, the design of EBG structures for suppressing undesired frequencies becomes more convenient, without resorting to the time-consuming full-wave simulator. In addition to the analysis for Embedded EBG structure, the application of Low Periodic Coplanar Photonic Band-Gap structure is discussed in this thesis. LPC-PBG structure is well-known for a good and wide-band ground-bounce reduction, but two main issue of signal integrity including the IR-drop and return path destruction are needed to be reconsidered in a high-speed digital circuit. Thus, some proposed PBG structures are discussed and analyzed with the design of power distribution network, for which the power integrity and signal integrity problem are taken into account.目 錄 第一章 研究動機與簡介............................... 1 1-1 研究動機..................................... 1 1-2 文獻回顧..................................... 2 1-3 章節概要..................................... 3 1-4 貢獻......................................... 4 第二章 接地雜訊的抑制............................... 6 2-1 高速數位電路接地雜訊現象與原因.............. 6 2-2 接地雜訊的抑制方法與比較.................... 8 2-3 電磁能隙結構簡介............................ 9 2-3-1 共平面式電磁能隙結構對於接地雜訊的抑制.. 9 2-3-1 內嵌式電磁能隙結構對於接地雜訊的抑制.... 11 第三章 電磁能隙結構基本設計方法..................... 18 3-1 內嵌式EBG結構設計概念....................... 18 3-2 縮小化螺旋式EBG結構......................... 20 3-3 等效電路模型與止帶設計...................... 22 3-4 內嵌式EBG結構設計流程圖......................... 28 第四章 電磁能隙結構參數分析與有效面積設計........... 39 4-1 幾何參數分析與討論.......................... 39 4-2 有效面積對抑制雜訊的影響.................... 45 4-3 內嵌式電容與螺旋縮小化結構的結合............ 47 第五章 電磁能隙結構於抑制寬頻雜訊之應用.............. 56 5-1 開槽平行板寬頻雜訊抑制...................... 56 5-2 訊號線跨槽線引發雜訊的改善.................. 60 5-3 結合去耦合電容最佳化的方法.................. 62 5-4 實驗模擬與驗證.............................. 65 第六章 低週期共平面式電磁能隙結構................... 81 6-1 共平面式PBG結構對於接地雜訊的抑制............... 81 6-2 電源層壓降問題的分析............................ 83 6-3 迴流平面破壞與訊號完整度的探討.................. 88 6-4 實驗模擬與驗證.................................. 91 第七章 結論......................................... 113 參考文獻.............................................. 1154463100 bytesapplication/pdfen-US電磁能隙結構低週期共平面式電磁能隙結構電阻壓降訊號完整度電源完整度接地雜訊Embedded Electromagnetic Band-GapLow Periodic Coplanar Photonic Band-GapIR-dropSignal integrityPower integrityGround bounce noisethesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/58736/1/ntu-95-R93942010-1.pdf
