[SOLVED] Plot in LTSpice - Vt0 vs. Vgs

[surpriya.7]

Hello,

Im trying to plot Vt0 vs. Vgs keeping a Vds constant.
In the 'pick a visible trace' list, I can see all the currents and the circuit voltages - but not the device parameters.

Please find the circuit below - its a real simple circuit.
Any help is appreciated.

Thanks
ssti

Vt0 is a constant of the model so there is no sensible plot with that as the x axis.

Are you people speaking of some kind of parametric anayisis?

In some SPICEs you can pick off model params - look for .mp()
or something like that.

The use for such sims is in things like predicting a Vgs-derived
pin electrical parameter, against WAT limits (presuming model
parameter ranges are fitted against WAT data). Though other
things (deltaL, k', Nss) will also play.
