Hello everyone, I want to plot gm vs. Vgs plot for a CNFET model. I am having trouble in plotting this curve. I do get Id vs. Vgs plot but how plot gm using the expression builder ?? I mean I put this thing in the Expression blank: derivative (I(Vdd))/derivative(Vgg); Result blank: Gm.... but I get the error that "derivative must take node object" ...
Also, by directly editing the netlist as .print Gm(nFET) or .print dc gm = par('gm(nFET)' ; no plot is obtained. I use HSPICE Ver: A-2008.03 .
please help me out. :-? Thanks in advance!
