Prof. Christian

This work is the design and characterization of a sample-and-hold circuit based on a novel implementation of the bootstrapped low-voltage analog CMOS switch. The heart of this circuit is a new low-voltage and low-stress CMOS clock voltage doubler. Through the use of a dummy switch, the charge injection induced by the bootstrapped switch is greatly reduced, resulting in improved sample-and-hold accuracy. Experimental results in a 0.18 um digital CMOS process show that a resolution greater than 10 bits can be obtained with a 1.0 V supply voltage. Circuit operation is also possible for supply voltages close to the transistor threshold (e.g., 0.65 V).

Biography:

is a Professor at the Universite du Quebec a Montreal (UQAM, Canada). Chris has a bachelor (first class honors) in electro-mechanical engineering, a M.A.Sc. (first class honors), and a Ph.D, respectively, all in electrical engineering. He worked with the Microelectronics Division of IBM (Essex, VT) as an Advisory Engineer. He served as a Consulting Engineer for ASIC North Inc. (South Burlington, VT). Most recently, he served as Advisory Engineer for Integrity Design and Research Corporation (Essex, VT). Dr Fayomi is a reviewer for the Natural Sciences and Engineering Research Council of Canada (NSERC) for their Discovery, Collaborative Research and Development, and Ideas to Innovation Grants. He also served as a reviewer for several journals and conference papers. In the context of biomedical circuits and systems, Dr. Fayomi has studied and proposed practical circuit techniques and design methods for low-voltage and low-power circuits with emphasis on solutions that do not require process enhancements. He has published widely. Based on Google search the result found at the Microsoft Academic Search is a total of 49 publications with 823 citations. He received three awards including the Best Analog Research Paper Award (23rd IEEE International Symposium on Integrated Circuits and System Design, 2010) and the Excellence in Teaching (UQAM, Canada). He has served as Chair-Elect for CASSFlexible (Circuits and Systems Society Flexible) which is a special interest group within the IEEE Circuits and Systems Society whose interests are Flexible Hybrid and Printed Electronics (FHPE) encompassing all aspects of the multi-disciplinary supply chains thereto but with emphasis on FHPE circuits and systems.
