Claim 16:
17. A device, comprising:
a microelectromechanical system (MEMS) gyroscope including:
a substrate;
a first mobile mass suspended over the substrate;
a second mobile mass suspended over the substrate; and
an elastic coupling structure including:
a first arm coupled to the first mobile mass, the first arm having a first stiffness;
a second arm coupled to the second mobile mass, the second arm having a second stiffness;
a first connection arm coupled to the first arm and extending from the first arm, the first connection arm having a third stiffness greater than the first and second stiffnesses;
a second connection arm coupled to the second arm and extending from the second arm, the second connection arm having a fourth stiffness greater than the first and second stiffnesses; and
a central compliant portion coupled to the first connection arm and coupled to the second connection arm, the central compliant portion extending from the first connection arm to the second connection arm, the central compliant portion having a fifth stiffness less than the third and fourth stiffnesses.
