Title:

L-IOT: a flexible platform for IoT autonomous systems : from ultra low power to low power applications

Abstract:

The Internet of Things is expected to comprise billions of connected devices, many of which will be wireless sensor nodes (WSN) communicating through a network. The nodes are spatially distributed and able to measure physical or environmental conditions while transferring data through a wireless link. Energy management and versatility are key issues for those objects are they are, most of the time, autonomous while handling many different applications requiring different performances. To cope with, we propose, in this talk, a flexible platform called L-IOT suitable for simple wake-up applications as well as more computing demanding applications. It is thus possible to achieve either ultra low-power with an Always-Responsive system or low power with an On-Demand system related to applicative constraints. The Always-Responsive system is based on many wake-up sources and a specific IT controller collecting wake-up information from: RF, sensors, harvesting or timer. A soon as enough energy is available and if the application requires it, the On-Demand system is woken-up with a standard M0+ micro-controller and specific co-processors for cryptography, data fusion, etc. Flexibility is also brought to this platform by many adaptive analog and digital building blocks globally optimized for high energy efficiency and potentially degraded in case of low energy availability.

Bio:

Edith Beigné joined CEA-LETI MINATEC in 1998 first working on RFID systems for biomedical applications. She focused then on asynchronous systems and circuits specifically for ultra low power mixed-signal systems and cryptographic circuits. Since 2005, she is in charge of the low power design team within the digital laboratory developing fine-grain power control and local voltage and frequency scaling innovative features. Since 2009, her main focus is to manage power and variability issues in advanced technology nodes for high energy efficiency. She was leading complex innovative SoC design in 65nm, 32nm bulk and now in 28nm and 14nm FDSOI technologies for adaptive voltage and frequency scaling architecture based on GALS structures. Her main focus is today automatic performance regulations for ultra low power circuits. She is part of ISSCC, ICCAD, ISLPED, DATE and ASYNC committees and JSSC editor.
