Patent ID: 7442918

Claim:
A MEMS oscillator, comprising: a body; a torsion member coupled to the body; a suspension coupled to the torsion member; and an oscillator body having a lateral extent away from a rotation axis defined by the torsion member and coupled to the suspension at a plurality of locations; wherein the suspension includes: a torque distribution member configured to distribute torque loads from the torsion member to substantially across the lateral extent of the oscillator body; an axial attachment member extending axially from the torque distribution member to the oscillator body, located substantially on-axis with the rotation axis; and two lateral attachment members extending from the torque distribution member to the lateral ends of the oscillator body along directions parallel to the rotation axis; wherein the axial attachment member is lower in cross sectional area than the torsion member to limit an amount of torque concentration where the axial attachment member couples with the oscillator body while reducing a lateral mode of motion or a pumping mode of motion, or combinations thereof.
