The fingerprint-readout function is widely used in high-tech devices such as notebooks, advanced keyboards, and automated access control, but it is quite rare to find it on the market as a stand-alone ...

In this paper, a CMOS readout circuit for capacitive fingerprint sensor fabricated by using low temperature polycrystalline silicon thin-film transistor (LTPS-TFT) process is presented. Based on ...

Novel capacitive fingerprint sensor techniques are described. We propose a novel sensor cell architecture to obtain high sensitivity, wide output dynamic range, and contrast adjustment. For the ...

Finger sensor circuit diagram showing sensing traces (33), drive/shield electrodes (35) and switches (42, 43). When not being used for fingerprinting purposes, the drive/shield electrodes can also ...

On low-voltage subsystems like a fingerprint sensor, the designer is frequently asked to provide two power rails to supply the I/Os (3.3 V, for instance) and the core voltage (1.8 V or 1.5 V, for ...

UPEK®, Inc. today announced the launch of Protector Suite 2009 software, the latest version of the award-winning fingerprint sensor software alre ...
