  • ELECTRET CAPSULE
    Publication number: 20230292056
    Abstract: The present invention relates generally to the field of electret capsule, and more particularly to a circuit configuration of an impedance converter integrated in an electret capsule such as for use in condenser microphones. The electret capsule of a microphone may include a gate biasing field effect transistor (FET) to facilitate biasing of a low noise FET. Advantageously, the use of low noise FET in the electret capsule of a microphone provides for a reduced cost, while achieving lower self-noise.
