Brief Bio
Youngcheol Chae is a professor of electrical and electronic engineering at Yonsei University and the CEO of XO Semiconductor, Inc., Seoul, Korea.
He received his B.S., M.S., and Ph.D. degrees from Yonsei University in 2003, 2005, and 2009, respectively. During his Ph. D. studies, he advanced oversampling ADCs through innovative design techniques including inverter-based amplifiers, which have been adopted today for many low-power data converters. From 2009 to 2011, as a post-doctoral researcher at Delft University of Technology in the Netherlands, he developed high-precision sensors and interface ICs.
After joining Yonsei University in 2012, he led a Yonsei Mixed-Signal IC group, focusing on innovative analog and mixed-signal circuits and systems for communication, sensing, and biomedical applications. This has resulted in 150+ peer-reviewed journal and conference papers and holds 50+ patents. Especially, his research team reported 60+ State-of-The-Art Chips in JSSC, ISSCC, and Symposium on VLSI Circuits.
Dr. Chae has been serving as a TPC member of the International Solid-State Circuits Conference (ISSCC), Asian Solid-State Circuits Conference (A-SSCC), and Custom Integrated Circuits Conference (CICC). He was a distinguished lecturer (DL) of IEEE Solid-State Circuits Society (SSCS). He received the ISSCC 2021 Takuo Sugano Award for Outstanding Far-East Paper, the Best Young Professor Award in Engineering from Yonsei University in 2018, the Haedong Young Engineer Award from the Institute of Electronics and Information Engineers (IEIE) Korea in 2017, the ISSCC Silkroad Award in 2017, the Outstanding Research Award of Yonsei University (2017, 2019, and 2020), and the Outstanding Teaching Awards of Yonsei University (2013, 2014). Currently, he is an Associate Editor of the Journal of Solid-State Circuits (JSSC) and Solid-State Circuits Letters (SSC-L).
