    摘要: A micromechanical motion sensor is capable of detecting a deflection imparted to an oscillatably mounted bar spring element excited to a permanent periodic oscillation by an electrostatic oscillating drive to which a periodic drive voltage is applied. To compensate non-linearities of the resonance frequency response of the bar spring element, a sum of a normal drive voltage signal and a compensation drive signal may be applied to a comb drive. In an alternative embodiment, separate compensation comb drive units may be additionally provided to the comb drive units used for the oscillation drive and a compensation voltage signal may be applied to them to compensate for the non-linearity.
