CMOS Capacitive Fingerprint Sensor Based on Differential Sensing Circuit with Noise Cancellation
In this paper, we introduce a differential sensing technique for CMOS capacitive fingerprint detection. It employs a new capacitive-sensing cell structure with charge sharing detection and readout circuit. The proposed technique also can eliminate the effect of parasitic capacitances by employing pa...
