Hello
I would like to ask derivative problems in cadance
what I want to do is to change dy ( when deriv form is d(vgs)/d(idc)
I want to get d(idc)/d(vgs) - I could only sweep idc on dc analyses)
first I ploted idc vs vgs by changing x axis from idc to vgs
now I need to get d(idc)/d(vgs) and d^2(idc)/d(vgs)^2
how can I do this?? when I use deriv. in calulator it derivates only by the sweeped parameter on dc analyses,idc
