摘要：

A direct contact finger mouse realized in 0.7-mu m digital CMOS is presented. It is based on the motion detection of the fingerprint images acquired with a capacitive sensor. Stroking and tapping the chip surface with the finger causes movement of the cursor and clicking-like mouse. By properly partitioning analog collective computation and digital processing, a power consumption of about 900 mu W at 5 V is achieved. The sensor area is 3.8 x 3.8 mm(2), and overall chip size is 7.7 x 6.7 mm(2).
