Abstract:
Waves are everywhere: the strings of musical instruments, a curious cloud pattern, the distribution of cars on a highway, and radio waves among mobile devices. In this talk, we focus on electromagnetic waves in high-frequency ICs, and discuss how they can be properly controlled to perform useful functions by engineering linear and nonlinear propagation media. Based on this approach, I will present four IC examples implemented in a CMOS process for 1) a new type of tunable delay line, 2) efficient clock distribution, 3) passive frequency division, and 4) <10-ps pulse generation.

Biography:
Wooram Lee is currently a Research Staff Member in the RF Circuits and Systems Group at the IBM T. J. Watson Research Center, where he is involved with the development of high performance mmWave phase array circuits and systems and highspeed serial link transceivers for optical communication. He is also an Adjunct Assistant Professor at Columbia University. 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 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. He received the IEEE Solid-State Circuits Pre-doctoral Fellowship for 2010-2011 and the Samsung Graduate Fellowship for 2007-2012. He was a recipient of the Best Paper Award of the IEEE Radar Conference in 2009.
