    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.

    摘要: A multi-axis integrated MEMS inertial sensor device. The device can include an integrated 3-axis gyroscope and 3-axis accelerometer on a single chip, creating a 6-axis inertial sensor device. The structure is spatially with efficient use of the design area of the chip by adding the accelerometer device to the center of the gyroscope device. The design architecture can be a rectangular or square shape in geometry, which makes use of the whole chip area and maximizes the sensor size in a defined area. The MEMS is centered in the package, which is beneficial to the sensor's temperature performance. Furthermore, the electrical bonding pads of the integrated multi-axis inertial sensor device can be configured in the four corners of the rectangular chip layout. This configuration guarantees design symmetry and efficient use of the chip area.
