简介
This manuscript presents the development of an integrated analog interface able to convert differential capacitive sensors variations into a DC voltage. The presented circuit exploits the architecture developed in previous works of the same authors, based on autobalancing bridge techniques, further improving its performances through the linearization of the input/output characteristic and the achievement of the full-range sensor variations capability. The interface takes advantage of Low Voltage and Low Power integrated circuit design techniques, optimizing performances for flux and force sensor. Simulated results with the AMS 0.35um standard CMOS technology have shown a very good agreement with the theoretical model developed, obtaining an error lower than 2.5% and a total power consumption of 5 mW. Moreover, waiting for the chip production, a discrete element board has been also implemented and …
