Abstract
A gyroscope includes a first drive mass driven in a first drive motion along a first axis, the first drive motion generating a first sense motion of a first sense mass in response to rotation of the gyroscope. The gyroscope further includes a second drive mass driven in a second drive motion along a second axis that is transverse to the first axis. The second drive motion generates a second sense motion of a second sense mass in response to rotation of the gyroscope. A drive spring system interconnects the two drive masses to couple the first and second drive motions so that a single drive mode can be implemented. The sense motion of each sense mass is along a third axis, where the third axis is transverse to the other axes. The sense motion is translational motion such the sense masses remain parallel to the surface of the substrate.
