Good morning,
i wrote a simple text file as "noise file name" for a Vdc (analogLib) in cadence. When i plot the PSD, the first region (flicker noise region) is characterized by "humps, because of a non linear interpolation, i suppose. How can i select a linear interpolation for these point?
Thank you!
Dario

Hi Dario

I am not sure that Cadence/spectre can do the linear interpolation.

What you should do is a interpolation of your points in matlab, and then feed this to Vdc in cadence.

hope it helps
