Abstract

Energy-efficient design approaches for always-on imaging will be reviewed. Circuit design techniques including dynamic voltage scaling (DVS), dynamic current scaling (DCS), and dynamic frequency scaling (DFS) will be described. In addition, energy-efficient architecture for image signal readout will be described. Finally, power reduction techniques by adaptively suppressing spatial and temporal bandwidth of image signals will be introduced. These energy-efficient design approaches will be illustrated with design examples including 1.36 μW/Frame adaptive CIS for wireless sensor node, 3.4 μW/Frame CIS with integrated feature extractor for objectdetection, and 45.5 μW (@ 15fps) always-on CIS for mobile and wearable devices.
