how to find out gm(transconductance) and its derivatives at perticular frequency?.Iam using cadence tool and spectrerf simulator.please respond..............
Re: how to find out gm and its derivatives at particular frequency
Hi erikl, I may not say clearly: whay I want is \[\frac{\partial I_D}{\partial V_G_S} \] over frequency. by using deriv() function, how to plot in frequency domain?
See my first answer above. This works for one single operating point Ids=f(Vgs) only. If you want this for several Vgs operating points, you can sweep it (use "Parametric Analysis").
