  • Angular velocity sensor and method for operating the same
    Publication number: 20070199377
    Abstract: An angular velocity sensor includes first and second vibrators having a movable portion with driving and detecting purpose movable electrodes and a fixed portion with first and second side driving and detecting purpose fixed electrodes. The driving voltages applied to the first side driving purpose fixed electrode in the first vibrator is a first driving voltage including direct and alternating voltages. The driving voltage applied to the second side driving purpose fixed electrode in the first vibrator is a second driving voltage including direct and alternating voltages. At least one of the direct voltages, one of the alternating voltages, or one of duty ratios of the first and second driving voltages is controlled so that the first vibrator vibrates opposite to the second vibrator.
