  Talk Title: Design of Silicon-Based Envelope-Tracking Power Amplifiers (ET-PA) for Highly-Efficient Broadband Wireless Applications; also a Briefing on Medical Electronics Research in My Group
  
  Abstract: The latest broadband wireless (4G/WLAN) standards utilize inherent spectral-efficient modulation schemes with high peak-to-average power ratios (PAPR) and wide signal bandwidth, which demand high linearity RF power amplifier (PA) design techniques that can offer excellent power-added efficiency (PAE) at both the maximum peak power and the power back-off levels to provide power saving. As suggested by the recent market trends and the literature, the dynamic power-supply modulation techniques (e.g., the envelope-elimination-and-restoration (EER) and the envelope-tracking (ET) schemes) are among the most effective methods for RF PA efficiency enhancement at both peak and back-off output power modes for various DoD and commercial applications. I would, therefore, present some of the latest design techniques, research, and market trends of high efficiency supply-modulated RF PAs, with emphasis on the silicon-based ET-PA design done in my group. I will also provide a brief highlight on some of the medical electronics research in my group.
  
  Biography: Donald Y.C. Lie (S’86–M’87–SM’00) received his B.S.E.E. degree from the National Taiwan University in 1987, and the M.S. and Ph.D. degrees in electrical engineering (minor in applied physics) from the California Institute of Technology, Pasadena, in 1990 and 1995, respectively. He has held technical and managerial positions at companies such as Rockwell International, Silicon-Wave (now Qualcomm), IBM, Microtune Inc., SYS Technologies, and Dynamic Research Corporation (DRC). He is currently the Keh-Shew Lu Regents Chair Professor in the Department of Electrical and Computer Engineering, Texas Tech University, Lubbock, Texas, and also an Adjunct Professor in the Department of Surgery, Texas Tech University Health Sciences Center. He has brought in multi-million dollars research funding and also designed real-world commercial communication products sold internationally. He was a Visiting Lecturer to the ECE Department, University of California, San Diego (UCSD) during 2002-2007 where he taught upper-division and graduate-level classes and affiliated with UCSD’s Center of Wireless Communications (CWC) and co-supervised Ph.D. students. Dr. Lie has been serving on the Executive Committee of the IEEE Bipolar/BiCMOS Circuits and Technology Meeting (BCTM), SiRF, MWSCAS, TSWMCS, and also on various Technical Program Committees (TPCs) for IEEE RFIC Symp., VLSI-DAT, ISCAS, PAWR, IEEE-NIH LiSSA, BIOCAS, etc. Dr. Lie has been awarded with the US NAVY SPAWAR SSC San Diego “Center Team Achievement Award”, Spring 2007; won 3 DRC Silver Awards of Excellence, 2005-2007; received IBM "FIRST" chairman patent award, 2001-2002 and Rockwell International’s “FIRST” engineering awards, 1996-1998. He and his students have won several Best Graduate Student Paper Awards and Best Paper Awards in international conferences in 1994, 1995, 2006, 2008 (twice), 2010 (twice), 2011, 2012, and 2013. Dr. Lie has been serving as an Associate Editor of IEEE Microwave and Wireless Components Letters (MWCL) since 2010, and as the Associate Editor-in-Chief (EiC) for the Open Journal of Applied Biosensor (OJAB) and on the Editorial Board of i-manager’s Journal on Electrical Engineering. He was a Guest Editor of IEEE Journal of Solid-State Circuits (JSSC) in 2009, the Special Topic Editor for IEEE MWCL in 2012. He has consulted for several IC design companies and an international research institute, and also for one of the best IP/Patent laws firms in the world. Dr. Lie has co-founded the NoiseFigure Research Inc. with his former student Dr. Lopez, and has coauthored over 150 peer-reviewed papers and book chapters and holds six U.S. patents. Dr. Lie’s group has published three most downloaded TOP 100 papers on the IEEE Xplore™ in Sept, 2012, June 2012, and Sept. 2009, respectively. His research interests are: (1) power-efficient RF/Analog IC and System-on-a-Chip (SoC) design and test; and (2) interdisciplinary and clinical research on medical electronics, biosensors, and biosignal processing.
