Claim 16:
17. A MEMS device comprising:
a MEMS sound transducer, wherein the MEMS sound transducer comprises a membrane structure and a counter electrode structure, wherein the membrane structure and the counter electrode structure are arranged to provide a differential excitation and read-out configuration of the MEMS sound transducer or to provide a single-ended excitation and read-out configuration of the MEMS sound transducer; and
control circuitry comprising:
a supply signal provider for providing a high-level supply signal,
a read-out circuitry for receiving an output signal from the MEMS sound transducer, and
a switching arrangement for selectively connecting the MEMS sound transducer to the supply signal provider, and for selectively connecting the MEMS sound transducer to the read-out out circuitry based on a control signal,
wherein the control circuitry is configured to provide the control signal having an ultrasonic actuation pattern to the switching arrangement during a first condition of the control signal, wherein the ultrasonic actuation pattern of the control signal triggers the switching arrangement for alternately coupling the high-level supply signal to the MEMS sound transducer.
