Fields of expertise
MissionThe Electronics Laboratory (ELab) know-how has originally been built around CMOS analog and mixed-signal ICs design. It has progressively been extended to MOS device physics and modeling. Some results obtained in modeling and circuit design techniques are translated into specific software tools as a subset of the main commercial CAD environment. Today, the main focus of the Elab in the field of IC Design, is concentrated on: - Ultra low power sensors interface, - High efficiency energy harvesting, - Electronics for Smart buildings management, - Real time electronics dedicated to Power grids emulation for smart grid technologies, - Smart power design and modeling for automotive applications.
