Abstract
A microelectromechanical acceleration sensor system including a microelectromechanical acceleration sensor element for detecting acceleration values acting on the acceleration sensor element, a sigma-delta analog-to-digital converter for converting the analog output signals of the acceleration sensor element into digital output signals, and a first signal generator element and a second signal generator element. The first signal generator element is connected between the acceleration sensor element and the analog-to-digital converter and being configured to apply a predetermined signal value to the output signals of the acceleration sensor element. The signal value of the first signal generator element corresponding to an acceleration value that is greater than the average gravity acceleration, and the second signal generator element being connected in a signal processing direction downstream from the analog-to-digital converter and being configured to correct the digital output signals of the analog-to-digital converter by the signal value of the first signal generator element.
