Abstract

This paper proposes an adaptive shuttering scheme to overcome the speed dependent distortion in swipe-type fingerprint sensor. Adaptive shuttering is achieved by displacement measurement based on pattern matching for two line images obtained from two rows of pixels. A compact, low-power pattern matching circuit is proposed as well. The proposed adaptive scheme was adopted to optical swipe-type fingerprint sensor to verify. The sensor was fabricated with 90nm CMOS process. The total area of the prototype sensor is only 3200μm×160μm and consumes 3.2mW. Experimental results demonstrate that the prototype chip produces speed-artifact-free image with 40μm×40μm resolution despite of irregular finger motion.
