If you’re looking for dozens of new circuits and DIY electronics project ideas, Elektor has you covered. The Elektor Circuit Special 2024 is out! In the 132-page edition is packed with a range of ...

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 sensitive and simple structure to measure low mutual capacitance of fingerprint sensor in 130-nm CMOS technology is presented. The proposed fingerprint sensor is integrated with ...

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 ...

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 ...

A zero-sink-current Schmitt trigger and window-flexible counting circuit for fingerprint sensor/identifier Abstract: Pixel-parallel architecture with 1b ADC per pixel achieves 6.4/spl mu/W dissipation ...
