IEEE EMC Society Distinguished Lecture Talk - The Myth about Ground

on December 5, 2018 from 6:00 PM to 8:00 PM

Speaker Dr. Zhiping Yang, Senior Hardware Manager at Google
Topic Info

Talk title: The myth about ground

GROUND is widely used in high-speed circuit modeling and simulation. However, there are a lot of misconceptions and misunderstandings about ground in the high-speed circuit industry. Does ideal ground really exist? If not, why do we use it in simulations? Should we connect the reference node of S-parameter model to ideal ground? Is ground bounce real and well defined? Should we put partial inductance and resistance on the ground net? What can we do or cannot do with S-parameter model? These questions are commonly asked by high-speed circuit designers. Answers from different people may be quite different and even contradictory. In this presentation, these questions will be answered with some simple, but powerful examples. At the end, the audience should have a better understanding about the ground and how to use it in high-speed simulations.

Speaker Bio

Zhiping Yang (S’97-M’00-SM’04) received his B.S. and M.S. degrees in Electrical Engineering from Tsinghua University, Beijing, China, in 1994 and 1997, respectively. He received his Ph.D. degree in Electrical Engineering from the University of Missouri-Rolla in 2000.  From 2000 to 2005, he worked for Cisco Systems, San Jose, CA, as a Technical Leader. From 2005 to 2006, he worked for Apple Computer, Cupertino, CA, as a Principal Engineer.  From 2006 to 2012, he worked in Nuova Systems (which was acquired by Cisco in 2008) and Cisco Systems, San Jose, CA, as a Principal Engineer.  From 2012 to 2015, he worked for Apple, Cupertino, CA, as a Senior Manager.  He is currently a senior hardware manager in Google Consumer Hardware Group.  His research interests include signal integrity and power integrity methodology development for Die/Package/Board co-design, high-speed optical module, various high-speed cabling solution, high-speed DRAM/storage technology, high-speed serial signaling technology, and RF interference.  He has published more than 40 research papers and 17 patents.  His research and patents have been applied in Google Chromebook, Apple iPhone 5S/6/6S, Cisco UCS, Cisco Nexus 6K/4K/3K, and Cisco Cat6K products.   Dr. Yang is a senior IEEE member and received 2016 IEEE EMCS Technical Achievement Award.
