Hi, I'm wondering how this circuit works. I understand that this is an electret microphone and the electret capsule (think J-fet) is what is amplifying the signal. What I don't understand is why there is a 0.1uF cap between the drain of the j-fet (or MC1) and the source ...or MICE (MICrophone Earth...I'm guessing....which is the LNA ground....I think). Wouldn't this provide a very low impedance to ground, filtering out the very signal we are trying to generate??? See PDF attached.
