碩士 === 國立臺灣大學 === 電信工程學研究所 === 94 === Embedded Electromagnetic Band-Gap-enhanced structures for the ultra-wide band noise suppression on split power/ground planes, signal line crossing slot, and decoupling capacitor combination are proposed, designed, examined, and validated. 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.
