Embodiments provide a MEMS microphone, comprising an output interface for providing an output signal of the MEMS microphone, and comprising a memory, wherein the output interface is configured to provide, in a normal mode of operation, a microphone signal as the output signal of the MEMS microphone, and wherein the output interface is configured to provide, in an initialization mode of operation, a data signal as the output signal of the MEMS microphone, wherein the data signal carries an information stored in the memory.

MEMS microphone

A system includes an analog-to-digital converter (ADC) and a digital modulator coupled to the ADC, wherein the digital modulator comprises an output for providing a digital signal, wherein the digital modulator comprises a main signal path and a feedback path, and wherein the feedback path comprises a first digital gain stage having a first adjustable gain range.
