I keep getting "Simulator returned no data". I've gone through the troubleshooting page, ensuring that none of the mistakes are present. I've also gone and moved around each component, to ensure they're actually connected. However, I can't seem to get it to successfully return, or evaluate either the simulator or solver.

I'm just getting started in this, so I'm sure it's something trivial. Here is the diagram:

Ok.. so I got this one to solve. I think I understand what I need to do for the signal generator + amp voltage.

However, now the behavior of the frequency response is not what I expected. The output voltage keeps getting amplified. It's like there is a cycle, but I can't see where.

Actually.. it's the Input that keeps getting amplified like crazy... that seems even weirder to me.

Here is another approach. I built this one based on this video: https://youtu.be/S7jrirsfkNw?t=1360

I'm not getting the same results. My output is from 3 to 5v... where it should be the same, but the current should be greater.
