Abstract
An angular rate sensor includes first and second proof masses spaced apart from a surface of a substrate. One each of first and second drive systems is interconnected with one each of the first and second proof masses. The first and second drive systems enable drive motion of the first and second proof masses along both of first and second axes in an orbital drive direction at a drive frequency, the first axis being perpendicular to the surface of the substrate and the second axis being parallel to the surface of the substrate. The sensor is sensitive to angular velocity about a third axis oriented parallel to the surface of the substrate and perpendicular to the second axis, and the drive frequency of the drive motion of the first and second proof masses changes in response to the angular velocity of the angular rate sensor about the third axis.
