RFIC design innovation for silicon-based D-band phased arrays
Abstract: D-band spectrum has attracted considerable interest to accommodate the explosive growth in wireless data capacity and emerging sensing applications. To overcome severe path loss and limited transistor performance at such high frequencies, the use of a large-scale phased array transceiver is essential. I will present RFIC design innovations to accelerate the development of a D-band phased array, including a passive phase shifter for calibration-free, precise phase control, a compact and low-power phased array transceiver, and low-noise bidirectional amplifier.
Bio: Dr. Wooram Lee is an Associate Professor with the Department of Electrical Engineering, Penn State University, University Park, PA, USA. He received his B.Sc. and M.S. degrees in electrical engineering from the Korea Advanced Institute of Science and Technology (KAIST) in 2001 and 2003, and his Ph.D. degree at Cornell University in 2012. From 2015 to 2020, he was a Research Staff Member in the RF Circuits and Systems Group at the IBM T. J. Watson Research Center, where he was involved with the development of high performance mmWave phased array circuits and systems and high-speed serial link transceivers for optical communication. He was also an Adjunct Assistant Professor at Columbia University from 2017 to 2020. From 2012 to 2015, he was with Broadcom, CA, where he worked on multi-Gbps CMOS transceivers and data converters for broadband communication in optical, copper and backplane applications.
Prof. Lee serves as an Associate Editor for the IEEE Transactions on Microwave Theory and Techniques, a Guest Editor for the IEEE Journal of Solid-State Circuits, a member of the Technical Program Committee of the IEEE BiCMOS and Compound Semiconductor Integrated Circuits and Technology Symposium (BCICTS), and International Microwave Symposium (IMS). He received the Best Student Paper Award (as a faculty advisor in 2023), and Best Industry Paper Award (in 2019) from IEEE Radio-Frequency Integrated Circuits (RFIC) Symposium, 2022 Asia-Pacific Microwave Conference (APMC) Prize (as a co-recipient), the IEEE Solid-State Circuits Predoctoral Fellowship (the sole winner) for 2010-2011 and the Samsung Graduate Fellowship for 2007-2012. He received the Best Paper Award of the IEEE Radar Conference in 2009.
