• abstract: An optical cell has been designed and fabricated using standard digital 1.6 /spl mu/m CMOS technology. It has been designed for applications to sensors where the image acquisition time of fast moving objects or documents is of primary importance. The cell contains a photodiode working in storage mode and a shielded MOS capacitor acting as analog frame buffer. A chip prototype containing 64 linear arrays of 64 cells whose size is 36/spl times/36 /spl mu/m/sup 2/ has been tested and measurements have proved the functionality down to microsecond-range of exposure times. By virtue of the proposed read-out technique, the sensor architecture provides simultaneous image acquisition of irregular moving objects allowing precise detection of position and motion.
