A yaw rate sensor () includes a movable mass structure () and a drive component () which is suitable for setting the movable mass structure () in motion (), and an analysis component () which is suitable for detecting a response () of the movable mass structure () to a yaw rate (&#x3a9;). A method for functional testing of a yaw rate sensor () includes the following steps: driving a movable mass structure (), feeding a test signal () into a quadrature control loop () at a feed point () of the quadrature control loop (), feeding back a deflection () of the movable mass structure (), detecting a measure of the feedback of the movable mass structure (), and reading out the response signal () from the quadrature control loop (). In the yaw rate sensor () and also in the method, the readout of the response signal () in relation to a processing direction () of the test signal () is provided between a feed point () for a test signal () and an actuator () for feeding back a deflection () of the movable mass structure ().

An oscillating circuit includes an analog oscillation element. The oscillating circuit includes at least one analog-to-digital conversion device. A method is for operating an oscillating circuit, in which a mechanical oscillator oscillates at a natural frequency. The oscillation amplitude is measured and digitized. A digital control signal is generated from this with the aid of a digital amplitude controller. A driving signal is generated, in turn, from the digital control signal, the driving signal driving the mechanical oscillator with the aid of a drive unit. This control loop stabilizes the oscillation amplitude.
