Beschreibung
Zusammenfassung:	A method for operating a capacitive MEMS sensor. The method includes: supplying a defined electrical potential on a deflectably mounted, seismic mass of the MEMS sensor; capacitively inducing a vibrational motion of the seismic mass with the aid of a clocked electrical control voltage; compensating for fluctuations in the supplied electrical potential on the seismic mass caused by the clocked electrical control voltage, by selectively charging and/or discharging an electrical storage element connected to the seismic mass in accordance with the frequency of the clocked electrical control voltage.
