Abstract

A yaw-rate sensor having a resonant driving frequency and a resonant Coriolis frequency. In addition, the yaw-rate sensor has at least one operating voltage, of which the resonant Coriolis frequency is a function. The resonant Coriolis frequency is adjusted to the resonant driving frequency with the aid of an adjustment voltage. A change in the resonant Coriolis frequency as a result of a change in the operating voltage may be compensated for, in that a suitably changed adjusting voltage may be produced from a compensation circuit.
