直角位相エラーおよび面外感知モードを検出するための電極構成を備えているＸＹ−軸ジャイロスコープ

摘要

Various embodiments include feedback circuits for tuning the drive modes of a shell-type gyroscope, while other embodiments include separate circuits for tuning the sense mode of a shell-type gyroscope to reduce or avoid quadrature errors. Still other embodiments include circuits to excite the sense modes (i.e., the out-of-plane modes) of a gyroscope without requiring the application of a rotation to the gyroscope, to ensure that the sense modes are aligned with the sense electrodes.
