Analog-intensive systems and integrated circuits for ubiquitous electronics

Guest Speaker: Dr. Simone GambiniABSTRACT:
Moore's law has decreased unit logic transistor cost to such an extent that communication is starting to rival computation as the main value-generating proposition in the semiconductor industry. While we are already exploiting the benefits of interconnected smart-phones, notebooks and laptops, future electronic devices will have both increased connectivity with other electronic devices, as well as much greater ability to interconnect with the environment to perform sensing and modification of physical quantities in their proximity. To accomplish these tasks both a low power, reconfigurable wireless subsystem as well as extensive mixed signal acquisition and processing sections to interface with several different sensors are required.I will introduce this talk showing examples of my past work in ultra-low power A/D conversion and MEMS-based wireless receivers.I will then focus on a fully integrated ultra-short-range bi-directional wireless system that avoids the use of a time reference by employing clock recovery techniques, and employs a dual-mode receiver and real-time error-estimation to improve interference robustness maintaining a state-of-the-art power dissipation of 300pJ/bit for the complete receiver. I will conclude showing ongoing work in low-voltage sensor-interfaces for chronical brain implants, and phase-spreading techniques for interference suppression in ultra-wideband systems.BIOGRAPHY:
Simone Gambini received the B.S. (cum Laude) from the University of Pisa in 2004, and the Diploma from Sant'Anna School of Advanced Studies in the 2004, both in Electrical Engineering. In 2009, he received the Ph.D. in Electrical Engineering from the University of California, Berkeley, where, he worked with Prof. J. Rabaey and E. Alon on low power ultra-short range transceivers and data acquisition circuits. Since 2010, he has been with Telegent Systems, a fabless semiconductor startup developing highly integrated mobile TV tuners. Prior to Telegent, he held industrial positions at Intel Research, Hillsboro,OR and Philips Research, Eindhoven.
Simone received the Analog Devices Outstanding Student Designer Award , an A-SSCC Best Student Paper Award and the U.C. Berkeley EECS Predoctoral Prize in 2006 and an Intel Foundation Ph.D. Fellowship in 2008. His research interests are in low-power wireless systems and integrated sensor interfaces.
