    Abstract: PROBLEM TO BE SOLVED: To at least partially overcome a conventional defect. SOLUTION: A sensing device 50' comprises a microelectromechanical structure, and a control loop 53' for controlling the microelectromechanical structure. The microelectromechanical structure comprises a stator element and a rotor element coupled together. The control loop 53' comprises a position interface 56 supplying a position signal VOUT indicative of the position of the rotor element and a one-bit quantizer 66 receiving the position signal VOUT and supplying a corresponding bit sequence OUT. The sensing device 50' comprises calibration devices 84 and 86 for calibrating the microelectromechanical structure and including a microactuator coupled to the rotor element and driving circuits 84 and 86 for driving the microactuator, and receiving the bit sequence OUT and supplying a driving signal VCAL correlated to a mean value MBS of the bit sequencer OUT to the microactuator in a given time window.

    Abstract: A digital high-pass filter (12) has an input (IN), an output (OUT), and a subtractor stage (20), having a first input terminal, a second input terminal and an output terminal. The first input terminal of the subtractor stage (20) is connected to the input (IN) of the digital high-pass filter (12) and the output terminal is connected to the output (OUT) of the digital high-pass filter (12). A recursive circuit branch (21) is connected between the output (OUT) of the digital high-pass filter (12) and the second input terminal of the subtractor stage (20). Within the recursive circuit branch (21) are cascaded an accumulation stage (23), constituted by an integrator circuit, and a divider stage (24). The cutoff frequency (f t ) of the digital high-pass filter (12) is variable according to a dividing factor (den) of the divider stage (24) .
