Donhee Ham earned a B.S. degree in physics from Seoul National University in 1996, where he graduated summa cum laude with the Presidential Prize, ranked top 1st across the College of Natural Sciences. Following a 1.5-year mandatory military service in the Republic of Korea Army, he went to Caltech for graduate training in physics. There he worked on general relativity and gravitational astrophysics while in physics. He changed his major to Electrical Engineering in 1998 and worked under Prof. Ali Hajimiri’s supervision and obtained a Ph.D. in electrical engineering in 2002 winning the Charles Wilts Prize awarded for the best thesis in Electrical Engineering. His doctoral work examined the statistical physics of electrical circuits. He was the recipient of the IBM Doctoral Fellowship, Li Ming Scholarship, IBM Faculty Partnership Award, IBM Research Design Challenge Award, and the fellow of the Korea Foundation of Advanced Studies.
In the past, my research interest has been focused on analog/mixed-signal integrated circuits for high-speed and low-power wireline communication systems and advanced packaging technologies. I’m also interested in biomedical systems (such as DNA sensing)and emerging techniques (such as solar energy). I have extensive integrated circuit design experience in both university and industry, where I led the development of over 20 integrated circuits, ranging from memory to phase-lock-loops, from low-noise NMR readout chips to high-speed data link chips (>10Gb/s), from graphene circuits to 3D integrated circuits.
I am co-recipient of the Journal of Solid-State Circuit (JSSC) Best Paper in 2009 and the Beatrice Editorial Excellence Award in the 2009 IEEE International Solid- State Circuits Conference (ISSCC).
In the past several years, I have published 7 ISSCC papers (5 1st-authored). I have published more than 30 peer-reviewed technical papers, 2 book chapters, and currently hold 4 U.S. patents and 10 pending patents.
Specialties:
1. analog/mixed-signal integrated circuits for high-speed wireline comm. systems: analog and digital PLLs, high-speed serdes, equalization circuits, clock generation & distribution
2. low-noise, low-frequency analog/mixed-signal ICs: LNAs, OPAs, DACs, etc.
Ricketts received his PhD in engineering and applied sciences from Harvard University and his BS and MS degrees in electrical engineering from Worcester Polytechnic Institute. Prior to joining academia, he spent eight years in industry developing more than 40 integrated circuits in mixed-signal, RF and power management applications. Ricketts’ research crosses the fields of physics, materials science and circuit design, investigating the ultimate capabilities of microelectronic devices and how these devices are harnessed by differing circuit topologies to produce the highest performing systems.
Nan Sun is Professor with Tsinghua University since 2020. He was Assistant and then tenured Associate Professor with University of Texas at Austin. He received B.S. degree from Tsinghua University in 2006, and Ph.D. degree from Harvard University in 2010. Dr. Sun received the NSF Career Award in 2013, and the IEEE SSCS New Frontier Award in 2020. He has published 28 JSSC papers and 47 ISSCC/VLSI/CICC papers. He has graduated 22 PhD students, 8 of whom are professors at top universities in the US and China. He serves on the Technical Program Committee of CICC and ASSCC. He was Associate Editor of TCAS-I, and a Guest Editor of JSSC. He serves as Distinguished Lecturer for IEEE Circuits-and-Systems Society from 2018 to 2020.
