Ultra-low-power systems for IoT

A Ph.D. candidate at Leti has developed an analog-digital converter and a signal filtering architecture that are setting new energy efficiency records. The innovation leverages 28 nm FD-SOI and a new, event-driven, signal processing mode, which means the systems are activated by the signal’s behavior—such as exceeding a given intensity threshold—rather than by a clock cycle. The research has resulted in several publications and two patents. The converter also earned the top slot in a Stanford University database for energy efficiency. Future applications will include IoT, a field in which current systems are not nearly energy-efficient enough to enable self-powering communicating objects with integrated energy harvesting systems.
