I have a ring oscillator CMOS that i would like to sweep the values of transistor's width, lets say, from 500n to 10u, and i would like to plot the frequecy of that oscillator x width, opening the calculator and using the function "frequency" of a VT value, but it is not working, i guess because when i use DC sweep, the simulator doesn't calculate the VT value and therefore doesn't calculate the frequency. There is any way of plotting the frequency vs width?
In cadence Virtuoso , Ade L , XL or GXL
Sorry, i am a begginer
