Virtual ground

[Mike(Mont)]

Figured it was easier to start a new thread but it's the same problem--coil goes to ground and I want to isolate it from the other circuits. The battery (voltage regulator), the signal generator all go to ground and I do not want the coil signal connected to these.

It just seems like this is what i might need but have no electronics knowledge here. I've watched some videos on this but that's as far as i got. I would appreciate if if anyone could steer me to a place I could learn more about this in order to design something. Thanks.

Well, at least I think that is what I need. Not really sure about anything here.

This article talks about the TLE2426 noise reduction.

Pretty sure I am over my knowledge ability here so don't anybody spend too much time on this or you will get frustrated with me for sure.

This is not your regular coil circuit and I think I need to get some professional help. I mean WITH THE CIRCUIT!!!
