converting this circuit to schematics will make it more confusing.
What made your netlist confusing to me, where a schematic would have
helped, is figuring out the interconnections between the subcircuits, and
between them and the other elements. Having nodes marked as "OUTPUT" that
are actually inputs to the subcircuit, does not help.
Your original note talked about both series and parallel connections, so I
expected to see both. Not seeing that, I had to do a bunch of tracing,
mentally re-constructing the missing schematic, to figure out whether this
was the series case or the parallel case.
So a schematic definitely would have helped. It would have made it less
confusing, not more.
actually the output should not have the distortion in -1.8kA ! and it
should continue constant like a diode :)
But you never described how this "distortion" manifests itself.
Specifically, what did LTspice calculate that differed from your hand
calculations of your formulas at the same operating point? (Indeed, did
you do any hand calculations at the point or points in question, that show
what the signal or signals ought to be?)
Saying that signals look funny is one thing. Saying that they are
incorrect requires some proof. You have not offered any proof that
LTspice's findings are incorrect. In doing that, I think that you would
probably find where the error is.
