Abstract
Disclosed herein is a device including a MEMS sensor configured to generate a first differential capacitance representing a change in capacitance from a first original sensing capacitance value and a second differential capacitance representing a change in capacitance from a second original sensing capacitance value, with the first and second original sensing capacitance values being mismatched. A compensation circuit is configured to generate outputs for compensating the first and second differential capacitances for the mismatch. A capacitance to voltage converter receives the first and second differential capacitances and the outputs of the compensation circuit as input and generates an output voltage as a function thereof.
