Greetings!
Does anyone know how to create a true voltage controlled resistor in Pspice (using E, F, G, and H controlled sources)?
I found a great site on how to create a VCR using text-based Spice:
Voltage-Controlled Resistor
I am wondering if there is a way to do this in the graphical PSpice student version.
The problem I am having is defining the gain of a controlled source. In text-based Spice, you can make the gain of a controlled source variable (for instance, you can make the gain of a controlled voltage source equal to the current through one branch multiplied by the voltage across a resistor in another branch). I don't *think* you can do this in graphical Spice because the GAIN field of a controlled source requires a constant number - the program gives an error if I try to put some kind of equation in for gain.

why wouldn't you use LtSpice? BI, BV source equations work - no "student" limitations, free, active support
