The structure is composed of three-dimensional interdigital capacitors (3D-IDC) and series U-shaped transmission lines periodically. The EBG structure can be miniaturized based on the LTCC fabrication technology. A theoretical circuit model which considers the inductive coupling in the 3D-IDC will be developed to predict the stop band. The accuracy of the proposed model will be verified by comparing with both the full-wave simulation and the measurement results. This modeling method is also employed to study the variation of band gap dependent on different geometrical parameters for the 3D-IDC and the U-shaped transmission line. A prototype is implemented using the LTCC technology with the dimension 1.2mm?3.8mm?0.728mm. Both simulation and measurement show the rejection band is from 2GHz to 5.5GHz. Over 25dB noise reduction in the stop band could be achieved. In addition, the suppressive ability is also verified in the chip-package co-simulation. From the simulation result, significant reduction of power noise could be found both in digital and mixed signal circuits.Abstract (Chinese)……………………...……………………………….Ⅰbstract……………………………………………………………...…..Ⅱable of Contents……………………………………………………..…Ⅲist of Figures………………………………………………...……........Ⅴcronyms…………………………………………………………...…..Ⅷhapter 1 Introduction.1 Research Motivation………………………………………..……1.2 Simultaneous Switching Noise (SSN) in Power Distribution Network (PDN) of IC packages………………………………….2.3 Chapter Outline of This Paper……………………………………4hapter 2 Various Solutions to SSN Problem.1 Component……………………………………………..………..6.1.1 Decoupling Capacitors…………………………………….6.1.2 Ferrite Beads……………………………...……………….11.2 Electromagnetic Band Gap Structure…………………………...14.2.1 Embedded EBG Structure…………………………..…….15.2.2 Coplanar EBG Structure………………….……………….19.3 Photonic Crystal Power/Ground Layer…………………………22hapter 3 A Miniaturized EBG Structure as A Component.1 Design Concept…………………………………………………27.2 Theoretical Model and Band Gap Prediction…………......…….31.2.1 Theoretical Model of The 3D-IDC………………..….…...31.2.2 Prediction of Stop Band……………….……...…......…....40.2.3 Parameter Effect on The Band Gap………...………..…....45.3 Power Integrity Performance and Co-simlation…………….......50.3.1 Fabrication and Measurement………………..….………..50.3.2 Chip and Package Co-simulation…….……...…………....53.3.2.1 Digital Noise Coupled to Digital Circuit………...55.3.2.2 Digital Noise Coupled to RF Circuit…………….58hapter 4 Conclusion eference 653663330 bytesapplication/pdfen-US寬能隙結構同步切換雜訊低溫共燒陶瓷製程EBGSSNLTCCthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/188282/1/ntu-98-R96942015-1.pdf
