Adaptive Architectures, Circuits And Technology Solutions For Future Iot Systems

Considering different sources of variations encountered by integrated circuits and systems today, adaptivity is a key challenge for designers. More specifically, this paper will propose different techniques, in the IoT domain, to cope with process-voltage-temperature variations as well as applicative and environmental variations. An overview of different techniques is given in the paper to be applied on gateways and also on IoT sensor nodes. Techniques like Adaptive Voltage and Frequency Scaling, adaptive imagers, wake-up radios or flexible security will be discussed. In any case, global power management is discussed in order to reach high energy efficiency and minimum energy losses while considering changing power supply environment.
