  "textContent": "The invention relates to the field of microelectromechanical systems (MEMS) gyroscopes. The MEMS gyroscope of the present invention drives oscillation of at least one proof mass in a primary drive mode at a first frequency and in a secondary drive mode at a second frequency, different to the first frequency. The primary drive mode and secondary drive mode are orthogonal. Sense circuitry measures oscillation of the at least one proof mass in a sense mode, which is orthogonal to the primary drive mode and the secondary drive mode, in order to determine the angular rate of rotation of the MEMS gyroscope about sense axes parallel to the movement of the at least one proof mass in the primary and secondary drive modes.",
