    摘要: According to one embodiment, a sensor includes a sensor element, and a controller. The sensor element includes a first sensor part. The first sensor part includes a first movable part which can vibrate. Vibration of the first movable part includes a first component and a second component. The controller is configured to perform to third mode operations. In the first mode operation, the controller is configured to derive a first rotation angle of the first movable part based on a first amplitude of the first component and a second amplitude of the second component. In the second mode operation, the controller is configured to derive a first angular velocity of the first movable part based on a change of a control signal. In the third mode operation, the controller is configured to supply a third mode signal to the first sensor part.

    摘要: In a first aspect, the angular rate sensor comprises a substrate and a rotating structure anchored to the substrate. The angular rate sensor also includes a drive mass anchored to the substrate and an element coupling the drive mass and the rotating structure. The angular rate sensor further includes an actuator for driving the drive mass into oscillation along a first axis in plane to the substrate and for driving the rotating structure into rotational oscillation around a second axis normal to the substrate; a first transducer to sense the motion of the rotating structure in response to a Coriolis force in a sense mode; and a second transducer to sense the motion of the sensor during a drive mode. In a second aspect the angular rate sensor comprises a substrate and two shear masses which are parallel to the substrate and anchored to the substrate via flexible elements.
