  • Systems and methods for isolation of torque and sense capacitors of an accelerometer
    Patent number: 7409862
    Abstract: A Micro Electromechanical Systems (MEMS) accelerometer device having a proof mass flexibly attached to a substrate. The device includes one or more sense capacitors formed between the proof mass and the substrate, one or more torque capacitors formed between the proof mass and the substrate, and an isolation device that electrically isolates cathodes of the sense capacitors from cathodes of the torque capacitors on the proof mass.
