发明名称 Device for bias potential generation for an oscillating rotation speed sensor
摘要 The invention relates to a device for generating bias voltages for the electrodes of a rotation rate sensor. By evaluating a rotation rate signal and a quadrature signal, control signals are generated, using an adaptive quadrature compensator, that are converted by means of a bias voltage generating arrangement into bias voltages that are delivered to the electrodes of an electrode arrangement disposed underneath the seismic mass or masses of the rotation rate sensor. As a result, the sensor structure can be inclined in such a way that the quadrature signal occurring at the output is minimized. In accordance with a further feature of the invention, the bias voltages generated by the bias voltage generating arrangement are modified, as a function of the output signal of a bandwidth adjusting circuit, in such a way that the amplitude frequency response of the detection motion has a desired bandwidth.
