1/f corner calculation for noise analyses

illaoi

I am looking for a way to calculate the 1/f corner of my output noise, found this but not sure if this reflects my question.

how to capture 1/f noise in spectre - RF Design - Cadence Technology Forums - Cadence Community


  • I think you could use a similar approach, but it's the transition from 10dB/decade to a lower slope. What you could do is use the same kind of script, but plot(slope) so you could then see what the slope looks like vs the decade number. You would expect to see the slope changing between decade 7 and 8 - and then you can decide on what an appropriate point to choose the transition would be.
