摘要
A dual-mode actuation and sensing circuit actuates both modes of an axisymmetric gyroscope and senses both outputs thereof. The sum of the two outputs provides a self-sustaining closed-loop oscillation signal, while the difference of the two mode outputs is used for extracting differential rate information while rejecting the common-mode bias terms of the gyroscope to provide online bias calibration. The proposed system and method facilitates scale factor calibration of an axisymmetric gyroscope. Furthermore, the difference output of the dual-mode gyroscope can provide a mode-split indicator signal which can be used to automatically match the gyroscope modes.
