| 20140374849 | ANGULAR RATE SENSOR WITH QUADRATURE ERROR COMPENSATION - An angular rate sensor includes a substrate, a drive mass flexibly coupled to the substrate, and a sense mass suspended above the substrate and flexibly coupled to the drive mass via flexible support elements. An electrode structure is mechanically coupled to, but electrically isolated from, the drive mass and is spaced apart from the substrate so that it is not in contact with the substrate. The electrode structure is configured to produce a signal that indicates movement of the sense mass relative to the electrode when the sensor is subjected to angular velocity. When the angular rate sensor experiences quadrature error, the drive mass, the sense mass, and the electrode structure move together relative to the sense axis. Since the sense mass and the electrode structure move together in response to quadrature error, there is little relative motion between the sense mass and the electrode structure so that quadrature error is largely eliminated. | 12-25-2014 |
