Abstract
Measures for regulating the electrical bias voltage at the measuring capacitor of a MEMS sensor element are described. A base voltage is applied to the measuring capacitor and regulated in such a way that the potential difference between the two electrode sides of the measuring capacitor corresponds to the setpoint voltage. The base voltage is regulated in a low-voltage range.
