Hi friends
For some theoretical LTspice work I need a model for a voltage controlled resistor that can produce both negative and positive resistance.
I thought of making a SUBCKT with a negative impedance converter made up of a single op-amp, but I think that kind of limits it's application. I would like it to be more simple and versatile like the ubiquitous resistor model in LTspice, would that be possible and what approach would most suitable?
