Abstract
A sensor has a suspended mechanical resonator being responsive to one of a linear acceleration and an angular velocity of the sensor such that a first area and a second area are subjected to opposite elongation movements and responsive to the other such that the first area and the second area are subjected to a common elongation movement, a first mechanical-electrical interface interacting with the first area, a second mechanical-electrical interface interacting with the second area, a common mode signal generator coupled to the mechanical-electrical interfaces with a common mode signal output, a differential mode signal generator coupled to the mechanical-electrical interfaces with a differential mode signal output, a first processing circuit coupled to the differential mode output, with an output for a first processed signal, and a second processing circuit coupled to the common mode output with an output for a second processed signal.
