Claim:
An angle measuring gyroscope which measures angular position arising from angular motion comprising: a substrate having a first surface; a first movable drive mass coupled to the substrate, movable in two orthogonal directions; a second movable slave mass, movable in two orthogonal directions; two sets of orthogonal drive electrodes coupled to the drive mass to drive the drive mass in two orthogonal directions and defined in a plane above the substrate; two sets of orthogonal sense electrodes coupled to the slave mass to sense movement of the slave mass in two orthogonal directions and defined in the same plane as the drive electrodes; and a two-degree of freedom suspension coupling the drive mass to the slave mass, the suspension restricting the range of motion of the drive mass to maintain movement of the drive mass within a linear regime, while allowing amplification of movement of the slave mass with respect to the drive mass.
