Abstract:
1. A MEMS gyroscope comprising: a first resonator configured for sensing rotation about a first axis x in a device plane, the first resonator including a first pair of shuttles suspended by a first plurality of suspension flexures and interconnected by a first fork, the first plurality of suspension flexures configured to allow the first pair of shuttles to be rotationally dithered in the device plane and to tilt out-of-plane about respective tilt axes y a second resonator configured for sensing rotation about a second axis y normal to the first axis in the device plane, the second resonator including a second pair of shuttles suspended by a second plurality of suspension flexures and interconnected by a second fork, the second plurality of suspension flexures configured to allow the second pair of shuttles to be rotationally dithered in the device plane and to tilt out-of-plane about a tilt axis x a first set of Coriolis sensing electrodes underlying the first pair of shuttles and positioned along an axis x a second set of Coriolis sensing electrodes underlying the second pair of shuttles and positioned along the first resonator tilt axes y
