Schematic diagram of an electret condenser microphone with a JFET amplification stage built into the capsule
Summary
[edit]DescriptionElectret condenser microphone schematic.svg |
English: A typical electret microphone preamp circuit uses a FET in a common source configuration. The two-terminal electret capsule contains an FET which must be externally powered by supply voltage V+. The resistor sets the gain and output impedance. The audio signal appears at the output, after a DC-blocking capacitor.
