  • Electronic circuit for a microphone and microphone
    Patent number: 10516942
    Abstract: 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.
    Type: Grant
    Filed: October 9, 2015
    Date of Patent: December 24, 2019
    Assignee: TDK CORPORATION
    Inventors: Gino Rocca, Daifi Haoues Sassene, Fabrizio Conso, Marco De Blasi, Marco Grassi, Piero Malcovati, Andrea Baschirotto
  • Electric circuitry to regulate a bias voltage for a microphone
    Patent number: 10506357
    Abstract: 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.
