A gyroscope includes a body, a driving mass, which is mobile according to a driving axis, and a sensing mass, which is driven by the driving mass and is mobile according to a sensing axis, in response to rotations of the body. A driving device forms a microelectromechanical control loop with the body and the driving mass and maintains the driving mass in oscillation with a driving frequency. The driving device comprises a frequency detector, which supplies a clock signal at the frequency of oscillation of the driving mass, and a synchronization stage, which applies a calibrated phase shift to the clock signal so as to compensate a phase shift caused by components of the loop that are set between the driving mass and the control node.
