A sensing device having a microelectromechanical structure made of semiconductor material, and a control loop for controlling the microelectromechanical structure, the microelectromechanical structure including a stator element and a rotor element electrostatically coupled together, and the control loop including a position interface supplying a position signal indicative of the position of the rotor element, and a one-bit quantizer receiving the position signal and supplying a corresponding bit sequence. The sensing device further includes a calibration device for calibrating the microelectromechanical structure, including a microactuator made of semiconductor material and coupled to the rotor element, and a driving circuit for driving the microactuator, and receiving the bit sequence and supplying to the microactuator a driving signal correlated to a mean value of the bit sequence in a given time window.
