Abstract:
An acceleration-sensing device having error correction includes a stator having at least one conductor affixed to a surface and a proof mass having a first conductor affixed at a first location relative to the at least one conductor affixed to a surface of the stator. The proof mass includes a second conductor affixed at a second location relative to the at least one conductor affixed to a surface of the stator, wherein an excitation signal applied to the first conductor of the proof mass brings about a force on the proof mass in the plane of motion of the proof mass that is substantially equally opposed by a force resulting from an excitation signal applied to the second conductor of the proof mass in the plane of motion of the proof mass.
