Torsten Reuschel studied at Hamburg University of Technology (TUHH), Hamburg, Germany, and at University of Waterloo, ON, Canada. He received the B.Sc. degree in general engineering sciences and the M.Sc. degree (Hons.) in electrical engineering in 2010 and 2013, respectively. He is a research and teaching assistant with the Institute of Electromagnetic Theory, TUHH, and plans to complete his Ph.D. degree in 2018. Torsten’s current interests include the computationally efficient analysis and design of PCB-based links and their equalization.
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.
