Title:  Electromagnetic Band Gap Structure for Common Mode Filtering of High Speed Diff Signals

Abstract: High Speed differential signals have become common place in the computer industry.  While the use of differential signaling can significantly improve the signal integrity, it does not eliminate EMC concerns.  Small amounts of rise/fall time mismatch, in-pair skew, or amplitude mismatch can create significant amounts of common mode signals, which, in turn, cause EMI emissions.  Discrete common mode filters are not commonly used due to their impact on the intentional signal as well as their cost.  Electromagnetic band gap (EBG) structures can filter unwanted common mode energy without reducing the signal integrity of the intentional signal.  This presentation will discuss how to design EBG common mode filters and show their use by simulations and measurements.

Bio:  Dr. Bruce Archambeault is an IEEE Fellow, an IBM Distinguished Engineer Emeritus and an Adjunct Professor at Missouri University of Science and Technology.  He received his Ph. D. from the University of New Hampshire in 1997.  His doctoral research was in the area of computational electromagnetics applied to real-world EMC problems.  He has taught numerous seminars on EMC and Signal Integrity across the USA and the world, including the past 15 years at Oxford University.

Dr. Archambeault has authored or co-authored a number of papers in computational electromagnetics, mostly applied to real-world EMC applications.  He currently serves as the President of the EMC Society.  He is the author of the book “PCB Design for Real-World EMI Control” and the lead author of the book titled “EMI/EMC Computational Modeling Handbook”.
