TL;DR: In this paper, the authors expressed their gratitude to all the people who inspired and helped me during my study in Georgia Tech. But they did not have much electromagnetic background, and their continuous support, guidance and encouragement led to my accomplishments and this dissertation would not been possible without their supports.
Abstract: To my family iv ACKNOWLEDGEMENTS I would like to express my gratitude to all the people who inspired and helped me during my study in Georgia Tech. This dissertation would not been possible without their supports. First and foremost being Prof. Madhavan Swaminathan, my academic advisor, who gives me the precious opportunity to work on the cutting-edge research in EPSILON group. I want to express my sincere appreciation to him. I still remember when I first joined EPSILON group four years ago, I did not have much electromagnetic background. It is his continuous support, guidance, and encouragement led to my accomplishments and this dissertation. His enthusiasm, patience in research will influence me throughout my life in the future. Also, I would like to extend my gratitude to my committee Suresh Sitaraman, for their time and help, and their valuable feedback to the research work in this dissertation. I would like to thank all the current and past members of the EPSILON group. Your friendship, opinions and help will always be appreciated. I am grateful to Dr. for his support and help in the early-stage of my research. I also would like to express my thanks to Dr. Jianyong Xie for spending his time on lots of technical discussions. I was fortunate to work with kind and genius colleagues who have graduated from EPSILON Antonio Astorino. It is fortunate for me to have so many colleagues working on various research topics and I learnt a lot from all of you. I also would like to express my gratitude to professors with whom I took my graduate courses: Prof. G. T. Zhou who provides me lots of help during my graduate study in Georgia Tech-Shanghai dual master degree program. Prof. Biing Hwang Juang whom I had lots of discussions before I start my PhD study. learnt lots of fundamental knowledge of various subjects by taking your courses. Finally, I owe my deepest gratitude to my family. Each time I encountered difficulty and setback, my parents are always there providing selfless love and support. All of my accomplishments throughout my life can not be achieved without the unconditional supports from my parents. This dissertation is dedicated to my parents. I wish their health and happiness.

TL;DR: In this article, a domain decomposition method (DDM) with a novel modeling of the DGS-EBG-based PDN is presented, and analytical models for the partitioned parts of the PDN are developed, and their impedance parameters are analytically extracted.
Abstract: In this paper, we present the power integrity analysis of a power distribution network (PDN) employing a segmentation technique based on the electromagnetic bandgap (EBG) structure with a defected ground structure (DGS). For efficient analysis of power integrity, a domain decomposition method (DDM) with a novel modeling of the DGS–EBG-based PDN is presented. In the DDM, analytical models for the partitioned parts of the PDN are developed, and their impedance parameters are analytically extracted. The resonant modes for the power integrity analysis are rigorously examined using the DDM and electric-field distribution. The effect of the DGS–EBG stopband on the resonant modes are analyzed. The proposed DDM and power integrity analysis are verified using full-wave simulation and measurements. The DDM result shows good agreement with the full-wave simulation and measurements.

TL;DR: In this article, a novel time-domain approach is proposed to extract the equivalent circuit models of power/ground planes by time domain reflection and time domain transmission waveforms, which can accurately predict the resonance behaviour of power and ground planes over a wide frequency range.
Abstract: Resonance noise, or power/ground bounce noise, between the power and ground planes of high-speed circuit packages is one of the main concerns of signal integrity or power integrity issues. A novel time-domain approach is proposed to extract the equivalent circuit models of power/ground planes by time-domain reflection and time-domain transmission waveforms. The extracted model can accurately predict the resonance behaviour of power/ground planes over a wide frequency range. These models can be efficiently incorporated into the HSPICE simulator for the consideration of power/ground bouncing noise in high-speed circuits.

TL;DR: In this article, the authors improve the power noise and eye diagram signal on printed circuits board design by impedance matching, where the power integrity introduces measured power initialization sequence, rails, and timing, and the eye diagram of signal improvement is compared for jitter, clock, and voltage noise.
Abstract: The objective of this study was to improve the power noise and eye diagram signal on printed circuits board design. The method was to analyze the transmission signal and improve signal integrity by impedance matching. The power integrity introduces measured power initialization sequence, rails, and timing. The eye diagram of signal improvement from the experimental result was compared for jitter, clock, and voltage noise. The result shows the improvement of the signal transmission on printed circuits board design to achieve optimal signal integrity.

TL;DR: Through proposed modelling method, this work will discuss High Frequency Suppression Structure with two approaches: the stop-band and pass-band in Z-shape and bandstop filter, which can effectively isolate the power and ground noise.
Abstract: With the development of high technology, the high-speed digital electronic circuit miniaturization, high operating frequency and high-speed transmission of data have continued to improve their functions. Because of the rapid development of semiconductor process, the electronic components become smaller, faster and faster processing speed. Compared to the past electronic circuit systems, the new electronic system will produce unpredictable electromagnetic interference (EMI), signal integrity (Signal Integrity, SI), power integrity (Power Integrity, PI) and other issues. That is to say, Electromagnetic Compatibility (EMC) has become an important topic in today's design of electronic circuits. Through proposed modelling method, we will discuss High Frequency Suppression Structure with two approaches: the stop-band and pass-band in Z-shape and bandstop filter. In the model, the PCB is divided into five segments of different sizes and rectangular power and ground plane. The High Frequency Suppression Structure are composed of two bandstop filters, rectangular resonant cavity and the Z-shape power bus. Finally, we can effectively isolate the power and ground noise.
