Power Optimisation in IoT Circuits

The Internet of Things (IoT) demands new challenges in the design of computing and electronics components. One of the challenges is the power reduction of this expanding network of connected devices, where the majority is permanently connected. In a large set of applications, another significant issue is reliability, especially on critical areas as health and transport. This talk shows an overview of physical design strategies that we have developed to reduce power consumption and to increase reliability in circuits that are components of the IoT, as the reduction of the number of transistors in IoT devices, using optimisation techniques and the physical design of circuits tolerant to radiation effects.

Ricardo Reis received a Bachelor degree in Electrical Engineering from Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, Brazil, in 1978, and a Ph.D. degree in Microelectronics from the National Polytechnic Institute of Grenoble (INPG), France, in 1983. Doctor Honoris Causa by the University of Montpellier in 2016. He is a full professor at the Informatics Institute of Federal University of Rio Grande do Sul. His main research includes physical design automation, design methodologies, fault tolerant systems and microelectronics education. He has more than 500 publications including books, journals and conference proceedings. He was vice-president of IFIP (International Federation for Information Processing) and he was also president of the Brazilian Computer Society (two terms) and vice-president of the Brazilian Microelectronics Society. He is an active member of CASS and he received the 2015 IEEE CASS Meritorious Service Award. He was vice-president of CASS for two terms (2008/2011), representing R9. He is the founder of the Rio Grande do Sul CAS Chapter, which got the World CASS Chapter of The Year Award 2011 and 2012, and R9 Chapter of The Year 2013, 2014, 2016 and 2017. He is a founder of several conferences like SBCCI and LASCAS, the CASS Flagship Conference in Region 9. He was the General or Program Chair of several conferences like IEEE ISVLSI, SBCCI, IFIP VLSI-SoC, ICECS, PATMOS. Ricardo was the Chair of the IFIP/IEEE VLSI-SoC Steering Committee, vice-chair of the IFIP WG10.5 and he is Chair of IFIP TC10. He also started with the EMicro, an annually microelectronics school in South Brazil. In 2002 he received the Researcher of the Year Award in the state of Rio Grande do Sul. He is a founding member of the SBC (Brazilian Computer Society) and also founding member of SBMicro (Brazilian Microelectronics Society).

Design of ultra low power circuits and sensors for biomedical application

The realization of ultra-miniaturized microsystems to measure physiological parameters on or inside the human body presents major technological challenges related to the design and power consumption of sensors and circuits. This talk will first review the concepts, results and conclusions of a UCL project aiming at an eye pressure sensing implant for glaucoma monitoring. In this frame, novel designs and optimizations were needed for the transfer and conversion of energy, very sensitive pressure sensor and read-out circuits, and for the wireless data transmission, to target an implant volume of a few mm3 only and a power consumption of about 100 uW. Secondly, the extension of the developments towards ultra-thin SOI CMOS microsystems for strain and temperature monitoring on bones or on the skin will be reported.

Denis Flandre received the EE and PhD degrees from Université catholique de Louvain in 1986 and 1990, resp. Since 2001, he is full-time Professor at UCL. He has authored more than 1000 technical papers or conference contributions. He is co-inventor of 12 patents. He has lectured many short courses on SOI technology, devices and circuits. He is involved in R&D on SOI MOS devices, digital and analog circuits, as well as sensors and MEMS, for high-speed, low-voltage low-power, microwave, biomedical, radiation-hardened and high-temperature electronics and microsystems. He is co-founder of CISSOID (SOI and high-reliability IC products), and scientific advisor of INCIZE (Semiconductor characterization and modeling for digital, analog/RF and harsh environment design) and e-peas (Energy harvesting and processing solutions for IoT applications). He has been a member of EU Networks of Excellence on High-Temperature Electronics, SOI technology, Nano-electronics and Micro-nano-technology, and of the SOI Industry Consortium.
