  "textContent": "A microelectromechanical gyroscope device (1) has: a detection structure (2), provided with a mobile mass; and an integrated electronic circuit (4), coupled to the detection structure and which provides a bias signal (S) to the detection structure to cause its oscillation at a resonance frequency and acquires a detection signal (S) from the detection structure indicative of a detected angular velocity. When the gyroscope device is powered, the integrated electronic circuit implements a start-up phase, following a previous power-down, wherein the mobile mass is biased to have an increase in the oscillation up to a target oscillation amplitude, followed by a maintenance phase at the target oscillation amplitude. The integrated electronic circuit is provided with a time counter stage (12) for measuring a duration of a time interval from the previous power-down and adjusts the bias of the mobile mass during the start-up phase as a function of the measured duration of the time interval.",
