Claim 0:
1. A device, comprising:
a microelectromechanical system (MEMS) gyroscope including:
a substrate;
a first mass and a second mass, the first mass and the second mass being suspended over the substrate and extending, at rest, in a plane of extension defining a first direction and a second direction transverse to the first direction;
a drive structure coupled to the first mass and configured, in use, to cause a movement of the first mass in the first direction; and
an elastic coupling structure extending between the first mass and the second mass and configured to couple the movement of the first mass in the first direction with a movement of the second mass in the second direction, and
wherein the elastic coupling structure includes a first portion having a first stiffness and a second portion having a second stiffness, the second stiffness being greater than the first stiffness.
