摘要： 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.

摘要： A method is described for balancing the phase-locked loop of an electronic analyzing device which analyzes the output signal of a sensor device, a yaw rate sensor in particular using the Coriolis effect having an oscillating mass which undergoes a deflection under the effect of an external yaw rate on the sensor device and the output signal representing a yaw rate signal, the electronic analyzing device having in addition to the phase-locked loop, a control loop, a quadrature control loop in particular, and the control loop is provided with a controller having an input and an output as well as with a modulator or mixer having an input which has a first electrical connection with the output of the controller. In order to reduce the percentage of sensor devices produced which, however, cannot be balanced the first electrical connection is interrupted between the output of the controller and the input of the mixer and a second electrical connection is produced between the output of the controller and the input of the mixer, the second electrical connection being made by connecting an attenuating element in between.

摘要： A method and an apparatus for synchronous demodulation of the multiply modulated rotation rate signal of a rotation rate sensor which comprises a spring-mass system that oscillates at its natural resonant frequency, and at least one capacitor for ascertaining a Coriolis effect acting on the spring-mass system or a rotation rate, the rotation rate being ascertained by a time-variable capacitance change, brought about by the rotation rate, of the at least one capacitor by multiple demodulation of a multiply modulated electrical signal that comprises a time-variable first electrical signal and a second electrical signal, overlaid thereon, at the natural resonant frequency of the rotation rate sensor, the amplitude of the second electrical signal of the time-variable capacitance change of the at least one capacitor being correspondingly modulated. To substantially reduce the outlay for synchronous demodulation, the first electrical signal is generated so that it exhibits a time-invariant phase relationship to the natural resonant frequency of the rotation rate sensor.

The device includes a starter loop for putting the sensor in a state of excitation via a starter signal via at least one of the sensor elements and for generating a sensor quantity, with the sensor quantity being a measure of a response of the sensor to the starter signal, and the starter signal having a substantially constant amplitude. A detector loop coupled to at least one of the sensor elements is also provided in the device for providing a measurement signal correlating with the motion parameter. The device further includes an analysis unit for providing an output voltage representing the motion parameter as a function of the measurement signal, a correction unit for keeping a substantially constant correlation between the output voltage and the motion parameter and for generating a correction signal as a function of the sensor quantity, and a multiplier providing the correction signal to the analysis unit.

摘要： A rotation rate sensor is described that operates on the principle of a resonant vibration gyrometer and is excited by an amplitude-regulated oscillator loop. This sensor is used for instance to ascertain the yaw speed of a vehicle. The effect of Coriolis acceleration is evaluated, which is a measure for the current yaw speed. To monitor the operability of the sensor and the associated electronics, an integrated self-test function is used, which as a so-called BITE function introduces a defined interference variable after actuation of a test input. This defined interference variable leads to an estimatable output voltage, whose occurrence is evaluated for error detection.
