how to sweep an equation which is formed using variables?

CKAITHANYA

Hi

I created an inverter with pmos and nmos and declared their widths as variables (Wp, Wn) by keeping the lengths constant. Now I want to plot VOUT vs  VIN  for different values of Wp/Wn ratio instead of doing parametric for Wp and Wn separately. I mean there is any way for directly sweeping the equation formed by variables.

    You could define your variable Wp to be (say) ratio*Wn and then sweep ratio for a fixed Wn. Does that do what you want? That seems fairly obvious, so maybe I've not understood your question.

    Regards,

    Andrew.
