Below is a suggested schematic update for the electret microphone bias network:
-
Electret Microphone:
- Add an Electret Microphone component.
- Connect its negative pin directly to Ground.
-
Bias Resistor:
-
Decoupling/AC Coupling Capacitor:
You can use the “Apply changes” option to update your schematic with these components and wiring:
- Place the Electret Microphone and connect its negative pin to Ground.
- Wire R1 (2.2kΩ) between VCC and the microphone's positive pin.
- Connect C1 from the junction (microphone output) to the subsequent amplifier input.
This network will provide the necessary biasing for your electret condenser microphone while ensuring that the DC bias is decoupled from the AC signal path.

The chosen components are a common starting point for an electret microphone bias network. A 2.2kΩ resistor is typically used to provide the necessary bias current from a 5V supply, and a 1µF capacitor is appropriate for AC coupling—blocking the DC bias while passing the audio signal.
Keep in mind that the exact values might be fine-tuned based on your specific microphone's datasheet and the required frequency response, but these are widely used and suitable for many electret condenser microphone applications.
