noisy cap
which cap has the lowest noise at 0.22-1uF? I am using a X7R and it picks up a lot of noise when I use it couple ac signal for inverting amplifier. Found that out after a lot of probing.
If I remove the cap and leave it hanging, no noise at all.
What cap should I use? this is for pre-amp for electret microphone.
thanks
