A 500-dpi AC capacitive hybrid flip-chip CMOS ASIC

A fingerprint detection technology that supports navigation, pointer, and fingerprint acquisition is described. The hybrid system consists of a silicon sensor substrate flip-chipped onto a mixed-signal ASIC. The sensor is linear and the finger is swiped over to scan the fingerprint. The navigation a...
