Abstract
A vibrating structure gyroscope includes an annular resonator arranged to vibrate in a plane in response to electrostatic driving forces and a set of capacitive drive electrodes arranged to apply a voltage creating an electrostatic driving force to excite a primary cos nθ resonance along a primary axis at a primary frequency f, such that Coriolis forces, resulting from an angular rate applied about an out-of-plane axis, induce a secondary cos nθ resonance along a secondary axis at a secondary frequency f. The gyroscope also includes digitally-controlled first and second sets to creating a static electrostatic balancing.
