Abstract / Description: 

Through decades of scaling the size of computing has gone to virtually zero. In foreseeable future, computing will be all around us, in mostly invisible forms, leading to hundreds of billions of connected computing-devices, sensors, things and people. The future smart connected world relies on energy-efficient computing and communication systems to enable battery operated always on always connected devices. The need for multi-Gbps wireless communication with battery-operated devices and extremely low-power self-sustainable sensor nodes will create an energy-gap that calls for order-of-magnitude energy-efficiency improvements in communication systems. Today's mostly-static wireless systems are designed for worst case channel, process and use case conditions, leading to sub-optimal power consumption when the respective conditions are not at worst case. This talk will highlight the design of context-adaptive zero-margin communication systems that adapt itself to real-time channel conditions, manufactured process-variations and use-cases to always operate with minimum power possible.

Shreyas Sen received his M.S.E.C.E. and Ph.D. degrees in Electrical and Computer Engineering from Georgia Tech, Atlanta, USA, in 2009 and 2011. He is currently working as a Senior Research Scientist in Signaling Research Lab, Intel Labs, Hillsboro, OR on high speed I/O and short range wireless. He had held intern positions with RFIC design group, Qualcomm in 2008 and a high-speed I/O group, Rambus in 2009. His research interests include design and test of analog/RF and mixed-signal circuits for high speed communication systems and low-power, variation-tolerant adaptive RF systems. He has authored/co-authored 2 book chapters, over 72 journal and conference papers and has 8 patents granted/pending.

Dr. Sen is a recipient of the Intel Corporation PhD Fellowship 2010-11, IEEE Microwave Theory and Technique Society (MTT-S) Graduate Fellowship Award 2008, UC Berkeley GSRC Margarida Jacome Best Poster Award 2007, IEEE ICCAD Best-in-Track Award 2014, IEEE VTS Honorable Mention Award 2014, Intel Lab Divisional Recognition Award 2014, Intel Lab Quality Award 2012, 2nd Best Paper Award in IEEE MTT-S RWS 2008, SRC Inventor Recognition Award 2008 and Young Engineering Fellowship (IISC Bangalore) in 2005. He serves as a Program Committee member of IEEE International Test Conference, IEEE VLSI Design among others. Dr. Sen has served as a Session Chair in DAC 2011, 2012 and ITC 2014.
