Abstract
A microelectromechanical systems (MEMS) accelerometer with extended operational capabilities beyond a closed-loop saturation. The present invention combines the closed-loop feedback signal and the measured proof-mass position into a hybrid acceleration measurement, which effectively provides an operating range equal to the traditional closed-loop operating range plus the sensor's mechanical open-loop range.
