Abstract: The gyroscope is formed by a driving system including a driving mass having an open concave shape; an accelerometer including a sensing mass and comprising mobile sensing electrodes; a linkage connecting the driving mass to the sensing mass. The sensing mass is surrounded on three sides by the driving mass and has a peripheral portion not facing the sensing mass. The mobile sensing electrodes extend integral with the sensing mass from the peripheral portion not facing the driving mass and are interleaved with fixed sensing electrodes. Thereby, there are no passing electrical connections extending below the sensing mass. Moreover the linkage includes springs placed equidistant from the center of gravity of the accelerometer, and the gyroscope is anchored to the substrate with anchoring springs placed equidistant from the center of gravity of the assembly formed by the driving system and by the accelerometer.

Abstract: A method of driving an inductive load connected to an output of a power stage includes comparing a signal representative of an instantaneous value of current flowing through the inductive load with upper and lower thresholds during a switching cycle. The method also includes alternately performing a magnetization phase during which current is forced through the inductive load, and a demagnetization phase during which a load inductance of the inductive load discharges through at least one of a slow recirculation discharge current path and a fast recirculation discharge current path. Switching is performed between the slow and fast recirculation discharge current paths during each switching cycle as a function of the comparison for reducing a ripple on an output signal from the power stage.
