Professor, Electrical and Computer Engineering
Bang-Sup Song, the Charles Lee Powell Chair in Wireless Communication, came to UCSD in 1999, after 13 years on the faculty at the University of Illinois at Urbana-Champaign, where he directed the Coordinated Science Laboratory. He was on the technical staff at AT&T Bell Laboratories, Murray Hill, receiving a Distinguished Technical Staff Award from AT&T Bell Laboratories in 1986, a Career Development Professor Award from Analog Devices in 1987, and a Xerox Senior Faculty Research Award from the University of Illinois in 1995. An IEEE fellow, he has served as Associate Editor, a Guest Editor, and a Program Committee Member for IEEE Transactions on Circuits and Systems, IEEE Journal of Solid-State Circuits, IEEE International Solid-State Circuits Conference, and IEEE Symposium on Circuits and systems. He received his Ph.D. from the UC Berkeley in 1983.
The design of wireless devices remains one of the most dynamic of integrated circuit (IC) spheres. Systems now are converging on a generic architecture using analog front-ends and tail-ends of massive DSP engines (digital signal processors). Professor Song is well qualified to provide perspective on this trend given his expertise in CMOS integrated data converters in RF systems. Noteworthy is his work with low-spurious data converters (a key driver of this evolution), and their subsystems and enabling techniques: flash architecture, variations using interpolation, averaging, subranging, and folding. From these, pipelining arrangements are derived, combinations are evaluated based on their features, and resolution-enhancing techniques (self-trimming) can be introduced, along with improvements to dynamic linearity.
