He was a co-recipient of several awards including the 1993 IEEE Communications Society's Best Tutorial Paper Award, the IEEE Electron Devices Society's 1997 Paul Rappaport Award for the Best Paper in an EDS publication during 1997, the1999 DAC Student Design Contest Award, the first place in the 2004 DAC/ISSCC Student Design Contest Award (operational category), and the ISSCC 2007 Beatrice Winner Award for Editorial Excellence. He held the Analog Devices Career Development Chair from 1994 to 1997. He received the NSF Career Development award in 1995, the IBM Faculty Development award in 1995 and the National Semiconductor Faculty Development award in 1996 and 1997.

His research interests include micro-power digital and mixed-signal integrated circuit design, wireless microsensor system design, ultra-wideband radios, and emerging technologies. He is a co-author of Low Power Digital CMOS Design (Kluwer Academic Publishers, 1995), Digital Integrated Circuits (Pearson Prentice-Hall, 2003, 2nd edition), and Sub-threshold Design for Ultra-Low Power Systems (Springer 2006). He is also a co-editor of Low Power CMOS Design (IEEE Press, 1998), Design of High-Performance Microprocessor Circuits (IEEE Press, 2000), and Leakage in Nanometer CMOS Technologies (Springer, 2005).

He has served as a technical program co-chair for the 1997 International Symposium on Low Power Electronics and Design (ISLPED), VLSI Design '98, and the 1998 IEEE Workshop on Signal Processing Systems. He was the Signal Processing Sub-committee Chair for ISSCC 1999-2001, the Program Vice-Chair for ISSCC 2002, the Program Chair for ISSCC 2003, and the Technology Directions Sub-committee Chair for ISSCC 2004-2007. He is the Technology Directions Chair for ISSCC 2008. He was an Associate Editor for the IEEE Journal of Solid-State Circuits from 1998 to 2001. He served on SSCS AdCom from 2000 to 2007 and he was the meetings committee chair from 2004 to 2007. He is a Fellow of the IEEE. He is the Director of the MIT Microsystems Technology Labs.
