An integrated micro-electro-mechanical gyroscope, comprising: a microstructure, having a first mass, which is free to oscillate along a first axis; a driving device coupled to said first mass, for maintaining said first mass in oscillation at a resonance frequency (ω R); inertial sensor means (6, 104, 106), which are mechanically coupled to said first mass so as to be fixedly drawn by said first mass along said first axis and have an axis of detection perpendicular to said first axis, said inertial sensor means (6, 104, 106) including: a second mass movable with respect to a rest position (Y 0) along said axis of detection; and displacement-detecting means (104, 106) for detecting a displacement of said second mass according to said axis of detection, wherein said displacement-detecting means (104, 106) include a force feedback loop, supplying electrostatic forces tending to bring back said second mass into said rest position (Y 0) in response to a displacement of said second mass according to said axis of detection; characterized in that said force feedback loop is of a purely analog type and comprises discrete-time switched-capacitor circuits; and in that the displacement-detecting means (104, 106) are configured to use a single pair of terminals (108c, 108d) of the second mass in time-division both for reading the displacements of the second mass and for actuation of the electrostatic forces. a microstructure, having a first mass, which is free to oscillate along a first axis; a driving device coupled to said first mass, for maintaining said first mass in oscillation at a resonance frequency (ω R); inertial sensor means (6, 104, 106), which are mechanically coupled to said first mass so as to be fixedly drawn by said first mass along said first axis and have an axis of detection perpendicular to said first axis, said inertial sensor means (6, 104, 106) including: a second mass movable with respect to a rest position (Y 0) along said axis of detection; and displacement-detecting means (104, 106) for detecting a displacement of said second mass according to said axis of detection, wherein said displacement-detecting means (104, 106) include a force feedback loop, supplying electrostatic forces tending to bring back said second mass into said rest position (Y 0) in response to a displacement of said second mass according to said axis of detection; a second mass movable with respect to a rest position (Y 0) along said axis of detection; and displacement-detecting means (104, 106) for detecting a displacement of said second mass according to said axis of detection, wherein said displacement-detecting means (104, 106) include a force feedback loop, supplying electrostatic forces tending to bring back said second mass into said rest position (Y 0) in response to a displacement of said second mass according to said axis of detection; characterized in that said force feedback loop is of a purely analog type and comprises discrete-time switched-capacitor circuits; and in that the displacement-detecting means (104, 106) are configured to use a single pair of terminals (108c, 108d) of the second mass in time-division both for reading the displacements of the second mass and for actuation of the electrostatic forces.
