Abstract
A sensor system includes a transducer for sensing a physical stimulus along at least two orthogonal axes and an excitation circuit. The transducer includes a movable mass configured to react to the physical stimulus and multiple differential electrode pairs of electrodes. Each of the electrode pairs is configured to detect displacement of the movable mass along one of the orthogonal axes. The excitation circuit is connectable to the electrodes in various electrode connection configurations, with different polarity schemes, that enable excitation and sampling of each of the orthogonal axes during every sensing period. For each sensing period, a composite output signal is produced that includes the combined information sensed along each of the orthogonal axes. The individual sense signals for each orthogonal axis may be extracted from the composite output signals.
