An electronic circuit for a microphone and a microphone are disclosed. In an embodiment, the electronic circuit includes a sigma-delta modulator having a configurable resolution and a mode selector, wherein the sigma-delta modulator is selectively operable in at least two operation modes and the mode selector is configured to determine a desired operation mode dependent on an externally provided control signal and to select the resolution of the sigma-delta modulator according to the determined operation mode.

Electronic circuit for a microphone and microphone

An electric circuit for regulating a bias voltage for a transducer of a microphone, the electric circuit including a bias voltage generator configured to generate the bias voltage for the transducer of the microphone and including a sound pressure detector configured to detect the sound pressure which impacts the transducer of the microphone. The bias voltage generator is configured to generate the bias voltage with a linear increasing gradient or linear decreasing gradient in response to the sound pressure detected by the sound pressure detector exceeding or falling below at least one threshold value of the sound pressure.
