Abstract
A gyroscope assembly includes a sense proof mass and a compensation proof mass. The sense proof mass has a sense frequency response in a sense dimension and is configured to move in a drive dimension in response to a drive signal, and to move in the sense dimension in response to experiencing an angular velocity about a sense input axis while moving in the drive dimension. And the compensation proof mass has, in the sense dimension, a compensation frequency response that is related to the sense frequency response.
