  • Self-calibrating oversampling electromechanical modulator and self-calibration method
    Patent number: 7461553
    Abstract: An oversampling electromechanical modulator, including a micro-electromechanical sensor which has a first sensing capacitance and a second sensing capacitance and supplies an analog quantity correlated to the first sensing capacitance and to the second sensing capacitance; a converter stage, which supplies a first numeric signal and a second numeric signal that are correlated to the analog quantity; and a first feedback control circuit for controlling the micro-electromechanical sensor, which supplies an electrical actuation quantity correlated to the second numeric signal.
    Type: Grant
    Filed: December 5, 2006
    Date of Patent: December 9, 2008
    Assignee: STMicroelectronics S.r.l.
    Inventors: Ernesto Lasalandra, Fabio Pasolini, Valeria Greco
