题目：Signal and power integrity of high speed digital interconnects 主讲人：Professor Jong-Gwan Yook --School of Electrical and Electronic Engineering, Yonsei University, Korea --IEEE EMC Society Distinguished Lecturer (Year 2012-2013) 主持人：李秀萍教授时间：2014年12月12日下午14:30—16:30 地点：教三—428 摘要：In this talk, signal and power integrity (SI/PI) of the mobile high definition link (MHL) system, having discontinuous and asymmetric structures have been analyzed. In the SI/PI analysis of the MHL system, three dimensional (3D) electromagnetic (EM) solver and time domain reflectometry (TDR) method are carried out. As a result, the differential signals with the discontinuous reference plane experience the degeneration of transmission characteristics due to the impedance mismatch at the discontinuities in return current path of the signals. Moreover, it is found that the SI/PI characteristics of the differential signal could be significantly degenerated, when the asymmetric guard traces with ground via holes for electromagnetic interference (EMI) reduction are located closer to the signal trace than the balanced reference plane. Therefore, SI/PI can be guaranteed with widely open eye diagram using the symmetric and continuous reference plane for the coupled signal lines in the high-speed digital interconnect. Also, wideband power plane isolation technique will be presented for enhanced power integrity. For the analysis of the quite complicated overall system, divide-and-conquer strategy has been successfully demonstrated. 主讲人简介： Jong-Gwan Yook has received the B.S. and M.S. degrees in electronics engineering from Yonsei University, Seoul, Korea, in 1987 and 1989, respectively, and the Ph.D. degree from the University of Michigan, Ann Arbor, USA, in 1996. He is currently a Professor with the School of Electrical and Electronic Engineering, Yonsei University. His main research interests are in the areas of theoretical/numerical electromagnetic modeling and characterization of microwave/millimeter-wave circuits and components with the emphasis on electromagnetic compatibility (EMC), design of radio frequency integrated circuits (RFIC) and monolithic microwave integrated-circuit (MMIC), analysis and optimization of high-frequency high-speed interconnects, including RF micro-electromechanical systems (MEMS), based on frequency as well as time-domain full-wave methods, and development of numerical techniques for multi-physics and multi-scale problems. Recently, his research team is developing various biomaterial as well as vital signal sensors, such as carbon-nano-tube RF biosensor for nanometer size antigen-antibody detection as well as remote wireless non-contact vital signal monitoring sensors. Professor Yook has served as a Distinguished Lecturer for the IEEE EMC society in the period of year 2012-2013 and received the Changsung Best Lecturer award in 2012. He also received the Excellence in Research and eaching award in Yonsei University in year 2005, 2006, 2009, and 2011. He was also serving as a Chair of the Korean EMC society in 2009-2012 and hosted EMC Korea workshops during this period. He has supervised more than 30 Ph.D. and over 80 M.S. graduate students. In the last fifteen years he has published more than 300 peer reviewed international as well as domestic journal papers and numerous international conference papers, and has advised various industries (Samsung, LG electronics, to name a few) and Korean Government for EMC and computational sciences aspects. http://portal.bupt.edu.cn//html/main/col51/2014-12/04/20141204161751177847992_1.html
