This talk will focus on Systems-on-Chip (SoCs) presented as part of the UAE SRC (Semiconductor Research Corp) Center of Excellenceon Energy Efficient Electronic Systems (aka ACE4S http://www.src.org/program/grc/ace4s/) involving researchers from 5 UAE Universities looking at developing new technologies aiming at innovative self-powered wireless sensing and monitoring SoC platforms. The research targetsapplications in self-powered chip sets for use in public health, ambient intelligence, safety and security and IoT.ACE4S is the first SRC center of excellence outside the US.

One such application, which we will discuss in details, is a ground breaking self-powered SoC platform for wearable health care. More specificallywe will present a novel fully integrated ECG signal processing system for the prediction of ventricular arrhythmia using a unique set of ECG featuresextracted from two consecutive cardiac cycles. Two databases of the heart signal recordings from the American Heart Association (AHA) and the MITPhysioNet were used as training, test and validation sets to evaluate the performance of the proposed system. The system achieved an accuracy of 99%.The ECG signal is sensed using a flexible, dry, Graphene-based technology and the system is powered up by harvesting human thermal energy. The systemarchitecture is implemented in Global foundries’ 65 nm CMOS process, occupies 0.112 mm2 and consumes 2.78 micro Watt at an operating frequency of 10 KHz and from a supply voltage of 1.2V. To our knowledge, this is the first SoC implementation of an ECG-based processor that is capable of predictingventricular arrhythmia hours before the onset and with an accuracy of 99%.

Biography: Mohammed Ismail a prolific author and entrepreneur in the field of chip design and test, spent over 25 years in academia and industry in the US and Europe.He obtained his BS and MS from Cairo University, Egypt and His PhD from the University of Manitoba, Canada in 1983, all in electrical engineering.

He is the Founder of the Ohio State University's (OSU) Analog VLSI Lab, one of the foremost research entities in the field of analog, mixed signal and RF integrated circuits and served as its Director. He also served on the Faculty of OSU's ElectroScience Lab. He held a Research Chair at the Swedish Royal Institute of Technology (KTH) where he founded the RaMSiS (Radio and Mixed Signal Integrated Systems) Research Group there. He had visiting appointments in Finland (Aalto university), Norway (NTH and University of Oslo), the Netherlands (Twente University) and Japan (Tokyo Institute of Technology).

He Joined KUSTAR, the UAE in 2011, where he held the ATIC (now Mubadala Technology) Professor Chair and is Founding Chair of the ECE Department. He is the Founding Director of the Khalifa Semiconductor Research Center (KSRC) and Co-Director of the ATIC-SRC Center of Excellence on Energy Efficient Electronic systems (ACE4S) targeting self-powered chip sets for wireless sensing and monitoring, bio chips and power management solutions. He recently joined Wayne State University, Detroit, Michigan as Professor and Chair of the ECE Department. His current research focuses on "self- healing" design techniques for CMOS RF and mm-wave ICs in deep nanometer nodes, energy harvesting and power management, wearableBiochips and SoCs for IoTs.

Dr.Ismail served as a Corporate Consultant to over 30 companies and is a Co-Founder of Micrys Inc., Columbus, Ohio, Spirea AB, Stockholm, Firstpass Technologies Inc., Dublin, Ohio and ANACAD-Egypt (now part of Mentor Graphics/Siemens).

He advised the work of over 50 Ph.D. students and of over 100 M.S. students. He authored or co-authored over 20 books and over 170 journal publications, 300 conference papers and has 14 US patents issued and several pending. He is the Founding Editor of the Springer Journal of Analog Integrated Circuits and Signal Processing and serves as the Journal's Editor-in-Chief. He served the IEEE in many editorial and administrative capacities. He is the Founder of the IEEE International Conference on Electronics, Circuits and Systems (ICECS), the flagship Region 8 Conference of the IEEE Circuits and Systems Society and a Co-Founder of the IEEE International Symposium on Quality Electronic Design (ISQED). He received the US Presidential Young Investigator Award, the Ohio State Lumley Research Award four times, in 1992, 1997, 2002 and 2007, IEEE 2016 CAS Society best paper award and the US Semiconductor Research Corporation's Inventor Recognition Award twice. He is a Fellow of IEEE.
