Improved model of a negative impedance converter

Extends from Modelica.Electrical.Analog.Interfaces.TwoPin (Component with two electrical pins).

Information

This is an improved implementation of a Negative Impedance Converter with opAmps.
Note that the opAmp model has to take into account saturation of the output.
Note that p.i + n.i <> 0 due to the active opAmp (with implicit supply) inside!

Note:

If voltage v is prescribed, the current i can be unambiguously determined.
If current i is prescribed, in the range between the zero crossings the voltage v has 2 or 3 possible solutions.
