Abstract

A MEMS device includes a MEMS sound transducer, and control circuitry. The control circuitry includes a supply signal provider for providing a high-level supply signal and 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 circuitry based on a control signal. The control circuitry provides the control signal having an ultrasonic actuation pattern to the switching arrangement during a first condition TX 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.
