    摘要: An integrated MEMS inertial sensor device is described. The device includes a MEMS inertial sensor overlying a CMOS substrate. The MEMS inertial sensor includes a drive frame coupled to the surface region via at least one drive spring, a sense mass coupled to the drive frame via at least a sense spring, and a sense electrode disposed underlying the sense mass. The device also includes at least one pair of quadrature cancellation electrodes disposed within a vicinity of the sense electrode, wherein each pair includes an N-electrode and a P-electrode.
