Abstract
A gyroscope includes a vibratory structure, and a control mechanism including at least a first electrode, and at least a second electrode adjacent the first electrode, wherein the vibratory structure is separated from the control mechanism by a gap, wherein to drive a vibration in the vibratory structure, the control mechanism is configured to apply an alternating electrical voltage between the first electrode and the second electrode, and wherein to sense motion in the vibratory structure, the control mechanism is configured to apply a direct current voltage bias between the first electrode and the second electrode.
