Christian Schuster received the Diploma degree in physics from the University of Konstanz, Germany, in 1996, and the Ph. D. degree in electrical engineering from the Swiss Federal Institute of Technology (ETH), Zurich, Switzerland, in 2000. Since 2006 he is full professor and head of the Institute of Electromagnetic Theory at the Hamburg University of Technology(TUHH),Germany. Prior to that he was with the IBM T.J.Watson Research Center, Yorktown Heights, NY, where he was involved in high-speed optoelectronic package and back plane interconnect modeling and signal integrity design for new server generations. His currents interests include signal and power integrity of digital systems, multiport measurement and calibration techniques, and development of electromagnetic simulation methods for communication electronics.
While a channel may pass a test, the remaining margin and thus its resilience against geometry or material variation in production may not be observable. However, such variations are critical because they may impede the performance or cause high volume manufacturing (HVM) products to fail. This coalition of authors has developed and demonstrated a polynomial chaos expansion (PCE) flow to analyze a full-featured 100GBASE-KR4 link starting from geometry specification to Channel Operating Margin (COM) margin at the receiver. Read on to see their award winning paper on the subject.
