Patent ID: 7444868

Claim:
A MEMS inertial sensor, comprising: one or more proof masses adapted to oscillate at a motor drive frequency; at least one sense electrode positioned adjacent to each of the one or more proof masses, the sense electrode adapted to sense proof mass motion along a sense axis perpendicular to a drive axis of the one or more proof masses; and a plurality of torquer electrodes positioned adjacent to each of the one or more proof masses, wherein the torquer electrodes comprise: one or more first torquer electrodes adapted to selectively control Coriolis-related motion of the one or more proof masses along the sense axis; and one or more second torquer electrodes adapted to selectively control quadrature-related motion of the one or more proof masses along the sense axis; and one or more time-varying rebalancing voltages applied to said torquer electrodes, the rebalancing voltages adapted to maintain a fixed capacitance between each sense electrode and its corresponding proof mass.
