  • 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

  • Patent number: 10177653
    Abstract: An impedance circuit for a charge pump arrangement and a charge pump arrangement are disclosed. In an embodiment, the impedance circuit includes a first current mirror circuit with a first bias serving as a current input terminal, a first output serving as a current output terminal and a first input for coupling with a pre-selected potential. The impedance circuit further includes a first charge pump for biasing the first current mirror circuit with a first reference current, wherein the first charge pump includes a first biasing output coupled with the first bias of the first current mirror circuit.
