    Tool(software) of reading data from curves

    Tool(software) of reading data from curves I once used a very small but useful software (tool), which can read and save the data from a figure just by clicking the mouse. It's very useful when people want to read out the values from certain curves in a figure of a technical paper. Otherwise...

    how to get Cgg~Vg in Spice3

    I know how to do it in hspice, but I don't know how to do it in Spice3f5. in hspice, we can do .param g=1.0 ... .ac lin 1 100K 101K sweep g lin 200 -2.0 2.0 but in spice3, .param and sweep can not be used. So if you know how to do it in spice3f5, please help. Thank you very much!

    how to get Cgg~Vg in Spice3

    Hi, I'm wondering how to do the spice3 simulation to get capacitance(for example cgg, cgd, cgs) versus Vg as Vg changes from -2 to 2V? Freq. maybe 1MHz. Can anybody provide a simple spice3 netlist? Thank you very much! Allen

    surface plot question, help!!!

    How could I plot a 3d surface graph where both x and y are functions of x? I could not use surf(x,y,z) as usual. For example, to plot a plane passing through 3 points (1,0,0), (0,1,0) and (0,0,1), how could I do it? Thanks a lot!
