Abstract
Various embodiments of the invention allow to reduce unwanted high-Q oscillations in capacitive MEMS sensors. In certain embodiments, stabilization of high-Q MEMS sensors is accomplished through a dedicated ultra-low power circuit that provides a bias voltage to one or more sensor electrodes during an OFF-phase. The bias voltage forces a balance condition that eliminates perturbations and enables smooth transitions that, ultimately, result in shorter sensor settling times.
