    摘要: A MEMS sensor comprises a substrate and at least one proof mass having a first plurality of combs. The proof mass is coupled to the substrate via one or more suspension beams such that the proof mass and the first plurality of combs are movable. The MEMS sensor also comprises at least one anchor having a second plurality of combs. The anchor is coupled to the substrate such that the anchor and second plurality of combs are fixed in position relative to the substrate. The first plurality of combs are interleaved with the second plurality of combs. Each of the combs comprises a plurality of conductive layers electrically isolated from each other by one or more non-conductive layers. Each conductive layer is individually coupled to a respective electric potential such that capacitance between the combs varies approximately linearly with displacement of the movable combs in an out-of-plane direction.
