    摘要: An integrated MEMS inertial sensor device includes one or more three-axis MEMS inertial sensor devices, such as accelerometers, with dual or single proof mass configurations. These designs can be compact and can decouple the motion of each axis to minimize the measurement errors due to cross-axis sensitivity. Some embodiments include a frame to decouple the motion of two axes and to provide geometric symmetry. Some embodiments also include double-folded springs. In a specific embodiment, the three axes of an integrated MEMS accelerometer device are entirely decoupled. Thus, the actuation of each axis, through a force due to acceleration, has little or substantially no effect on the other axes.

    摘要: An integrated MEMS inertial sensing device can include a MEMS inertial sensor with a drive loop configuration overlying a CMOS IC substrate. The CMOS IC substrate can include an AGC loop circuit coupled to the MEMS inertial sensor. The AGC loop acts in a way such that generated desired signal amplitude out of the drive signal maintains MEMS resonator velocity at a desired frequency and amplitude. A benefit of the AGC loop is that the charge pump of the HV driver inherently includes a ‘time constant’ for charging up of its output voltage. This incorporates the Low pass functionality in to the AGC loop without requiring additional circuitry.

    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.
