Abstract:
1. A sensor, comprising: a yaw-rate sensor having a resonant driving frequency and a resonant Coriolis frequency, the yaw-rate sensor further having at least one operating voltage of which the resonant Coriolis frequency is a function; an arrangement configured to adjust the resonant Coriolis frequency to the resonant driving frequency using an adjustment voltage; and a compensation circuit, the aid of which a change in the resonant Coriolis frequency as a result of a change in the operating voltage is compensated for by adjustment of the voltage; wherein the sensor is controlled by a first voltage and a second voltage, where the second voltage is the sum of a voltage applied at a time, and a voltage change which occurs during operation of the sensor, where the voltage change is an input signal for the compensation circuit.
