    Abstract: A gyroscope includes a body (6), a driving mass (7), which is mobile according to a driving axis (X), and a sensing mass (8), which is driven by the driving mass (7) and is mobile according to a sensing axis (Y), in response to rotations of the body (6). A driving device (3) forms a microelectromechanical control loop (18) with the body (6) and the driving mass (7) and maintains the driving mass (7) in oscillation with a driving frequency (ω D ). The driving device (3) comprises a frequency detector (25), which supplies a clock signal (CK N ) at the frequency of oscillation of the driving mass (7), and a synchronization stage (29), which applies a calibrated phase shift (Δϕ) to the clock signal (CK N ) so as to compensate a phase shift caused by components (20, 21, 22) of the loop (18) that are set between the driving mass (7) and the control node (25a).

    Abstract: The integrated magnetic sensor (19) for detecting an external magnetic field, is formed by a body (21) of semiconductor material having a surface (25); an insulating layer (28, 36, 37) covering the body of semiconductor material; a magnetically sensitive region, for example a Hall cell (22), extending inside the body; and a concentrator (33) of ferromagnetic material, extending on the Hall cell and having a planar portion (35) extending parallel to the surface of the substrate on the insulating layer (28, 36, 37). The concentrator (33) terminates with a tip (34) protruding peripherically from, and transversely to, the planar portion (35) toward the Hall cell (22). When the magnetically sensitive region is a sensing coil (3a-3d) of a fluxgate sensor, it is formed on the substrate, embedded in the insulating layer, and the tip (47) of the concentrator can reach as far as the sensing coil.
