Huh? why is it occilating?

Ctrl goes to ground through a capacitor and GND is directly grounded

It is not oscillating... I think that is numerical noise that is present in EC simulations, check out hurz's circuits you'll find some demonstrations in there...

Yeah, there are many interpretations of that noise. I believe it to be encoded on purpose to destabilize oscillators, and such, because in an ideal environment, nothing can truly oscillate.

No, I've seen that noise in some of my circuits, this is not one thing like it.

Yes it is definetively numerical noise

No circuit can create a signal that has "voltage gaps", where the instantaneous voltage is not determined and after that suddenly start at some level again.

I think it emulates the thermal noise of resistors

amogh123 my thought exactly. Or ground noise. See in a perfect environment nothing will oscillate. So i guess Igor put in some fail safes if your phone can't ,,shake to start''.

I might actually know what this is, there is really just >3< grounds so, there is 3 different outputs.

No, most likely it's numerical noise, or a small noise generator, to kick-start oscillators. I made a circuit a while back and it seema that EC doesn't have a perfect ground either. The ground is covered with white noise but at such an attenuation, that it poses no noise at all. I think the lowest value i measured was around -150 -160dB. That may partially be causing the noise
