Titre: SSCS Distinguished Lecture Tour / Silicon‐based Circuits and Systems at the Terahertz Frontier
Conférencier: Ullrich Pfeiffer , Université de Wuppertal, Allemagne
Lieu: École Polytechnique de Montréal, pavillon principal, Galerie Rolland ,
Date et heure:
lundi le 10 novembre 2014 de 13:00 à 14:00

Résumé: The push for novel applications in the sub‐mmWave region of the electromagnetic spectrum has raised the bar on RF circuit design and characterization. Continued device scaling enables circuits to operate at frequencies so high that contact‐less wafer testing (in free space) is the last resort. This talk will summarize this frontier. It follows practical CMOS and SiGe BiCMOS design examples including 0.5 THz high‐power oscillators, sub‐ harmonically operated receivers and transmitters up to 0.8 THz, and broadband direct detectors for active imagers running well beyond 1 THz.

Note biographique: Ullrich R. Pfeiffer received the diploma degree in physics and the Ph.D. in physics from the University of Heidelberg, Germany, in 1996 and 1999 respectively. In 1997 he worked as a research fellow at the Rutherford Appleton Laboratory, Oxfordshire England. From 1999‐2001 he was working as a Postdoctoral Researcher, at the University of Heidelberg on real‐time electronics for particle physics experiments at the European Organization for Nuclear Research (CERN), Switzerland. From 2001 to 2006 he was with the IBM T.J. Watson Research Center where his research involved RF circuit design, power amplifier design at 60GHz and 77GHz, high‐frequency modeling and packaging for millimeter‐wave communication systems. In 2007 he received a European Young Investigator Award and lead the THz electronics group at the Institute of High‐Frequency and Quantum Electronics at the University of Siegen, Germany. Since 2008 he holds the High‐frequency and Communication Technology chair at the University of Wuppertal, Germany. He was the co‐recipient of the 2004 and 2006 Lewis Winner Award for Outstanding Paper at the IEEE International Solid‐State Circuit Conference, the co‐recipient ofthe 2006 IBM Pat Goldberg Memorial Best Paper Award, the 2008 EuMIC Best Paper Award, the 2009 Best RFIC Oral Paper Presentation, and the 2010 EuMC Microwave Prize, and the 2012 Jan Van Vessem Award for Outstanding European Paper at the 2012 IEEE International Solid‐State Circuit Conference. He is a Senior Member of IEEE, and serves on the technical program committee of the International Solid‐State Circuits Conference, the European Solid‐State Circuits Conference, the Bipolar/BiCMOS Circuits and Technology Meeting, the Silicon Monolithic Integrated Circuits in RF Systems Conference, and the European Microwave Integrated Circuits Conference. He has authored and co‐authored 100+ publications and has been principal inventor and co‐inventor of 10+ US and international issued patents, relating to RF, millimeter‐wave, terahertz communication/imaging circuits and sensors.
