Low Power Circuits for Future Digital Systems

As CMOS technology scales to deep submicron lengths, designers face new challenges in determining the proper balance of aggressive high performance devices and lower performance devices to optimize system power and performance for a given application. Determining this balance is crucial for battery powered handheld devices where device leakage and active power limit the available system performance. For high performance systems, similar trade-offs are being made between integration of increasingly high performance and leaky devices and the cost of cooling and power delivery. This talk will explore this question and describe research in developing low power techniques which exploit the capabilities of advanced CMOS technology.

Stephen Kosonocky Recieved a BS, MS, and PhD from Rutgers University, New Brunswick, NJ, in 1986, 1991 and 1994. From 1986-1992 he was a Research Scientest at Siemens Corporate Research in Princeton, NJ, where he worked on CMOS Digital and Analog circuit design. From 1992 to 1993 he was with Samsung Princeton Design Center where he worked on mixed signal BiCMOS video circuits. In 1994 he joined IBM T.J. Watson Research Center, Yorktown Heights, NY where he has developed prototype Embedded DRAM Systems-on-chip applications, contributed to the circuit, logic and Micro-architecture design of Daisy and Boa VLIW processors. In 2000 began leading a team on Low Power Circuits and Technology for Digital Communication Engines for hand-held applications, and since 2003 he is focusing the team on low power circuit techniques for high speed microprocessors. He has been awarded 8 U.S. Patents, with 19 Patents Pending and has received his Sixth Patent Plateau Award from IBM. He has been on the Technical Program Committees for the ACM/IEEE 2001, 2002, 2003, 2004International Symposium on Low Power Electronics & Design, IEEE 2002, 2003, 2004 International Solid State Circuit Conference, and the IEEE 2001, 2002, 2003, 2004 Symposium on VLSI Circuits. He has authored or co-authored over 30 publications. He was the IEEE Solid-State Circuit Society Membership Chair from 1998-2000 and a member of the IEEE Electron Device Society Membership Committee from 1997-2004, and Chair of a 1999 IEEE Technical Activities Board Focus Committee on retaining young members.
