Nexxim Simulator > Voltage-Controlled Resistor, Linear
Linear VCR Netlist FormatThe format for a linear voltage-controlled resistor (VCR) is: Gxxxx out+ out- VCR in+ in- [TRANS=]transfactor [MAX=val] [MIN=val] [M=val] [TC1=val] [TC2=val] [SCALE=val] out+ is the positive node and out- is the negative node of the resistor. VCR is required for the G element voltage-controlled resistor type. in+ and in- are the positive and negative nodes for the control voltage. The label TRANS= is optional, but the transfactor must be given. transfactor is the conversion factor from input voltage to output resistance.
Linear VCR Netlist ExampleGres1 22 23 VCR 32 33 200 MAX=1000 MIN=50 NotesThe functional equation for the linear VCR is: R(n+, n-) = [transfactor ´ (V(in+) - V(in-)) ´ SCALE ´ (1 + DT ´ TC1 + DT2 ´ TC2)] / M If the result is less than MIN, R(n+, n-) = MIN If the result is greater than MAX, R(n+, n-) = MAX
