Patent ID: 8752429

Claim:
A microelectromechanical device comprising: a microstructure including a fixed structure and a driving mass movable with respect to the fixed structure with a first degree of freedom according to a driving axis; and a sensing device forming a microelectromechanical loop with the microstructure, the microelectromechanical loop being configured to keep the driving mass in oscillation according to the driving axis at a driving frequency; wherein the sensing device comprises: a discrete-time sensing interface coupled to the microstructure and configured to sense a discrete-time position of the driving mass with respect to the driving axis, the sensing interface including a discrete-time charge amplifier configured to sense the discrete-time position of the driving mass and provide a discrete-time detection signal that indicates the discrete-time position of the driving mass; and a controller configured to control an oscillation amplitude of the microelectromechanical loop based on the discrete-time detection signal that indicates the discrete-time position of the driving mass.
