In this work we present the development of an integrated CMOS analog interface able to convert differential capacitive sensors variations into a DC voltage. The presented circuit is based on autobalancing bridge techniques improving its performances through the linearization of the input/output characteristic and the achievement of the full-range sensor variations capability. Comparison between theoretical and measured interface static behaviour results are reported.
