An advanced fingerprint sensor LSI and its application to a fingerprint identification system

Abstract

We developed an advanced fingerprint sensor LSI that features a novel sensor structure, sensing circuit, and calibration circuit, using the 0.5-/spl mu/m CMOS process/sensor process. The LSI is reliable, sensitive, and tolerant to changes in the sensor surface conditions for capturing clear fingerprint image over long-term use. We also introduce a… (More)
