Minimum energy per operation is typically achieved in the subthreshold region where low speed and low robustness are two challenging problems. This paper studies the impact of Back Biasing (BB) schemes on these features for FDSOI technology. We show that Forward BB can help cover a wider design space in term of optimal frequency of operation while keeping(More)
For a massive yet sustainable Internet-of-Things, ultra-low power management and voltage regulation are required to operate the nodes on ambient energy harvesting (EH) while delivering the required supply voltages to the sensing, computing and communication blocks. Latest related results obtained in the electronic circuits and systems (ECS) group include(More)
Adding vision capabilities to wireless sensors nodes (WSN) for the Internet-of-Things requires imagers with high resolution and ultra-low power. Based on previous work [1], a time-based imager adapts the three key innovations from [3] and introduces new features: extended resolution, migration to a more mature CMOS technology and integration of a DC/DC(More)
