Parameter variations cause unavoidable nonuniformities in Infra-Red Focal Plane Arrays and other integrated sensors. Since these nonuniformities change slowly with time, calibrating sensors one-time only is not suitable{much more frequent calibration is required. We have developed an algorithm that continually calibrates an array of sensors that contain gain and ooset variations. This algorithm has been mapped to analog hardware and designed and fabricated with a 2um CMOS technology. Measured… CONTINUE READING
