Abstract :
Smart sensors are currently demanded in various kinds of applications to pave a way for better life. To reach this goal, it is necessary to provide energy-efficient solutions with analysis capability. Though state-of-the-art SoC´s can meet μW-level processing requirements, front-end sensors remain a bottleneck to be solved. In this paper, a few sensors based on event-driven techniques to improve energy-efficiency and accuracy will be first addressed. Then an ECG-SoC for mobile health-care applications will be described and illustrated.
