Regarding PNOISE results obtained from Spectre-RF

sarfraz

Hi,
What sort of spectral density is obtained when we do Pnoise analysis in Spectre-RF.
Is it power spectral density of phase or is it power spectral density of voltage?

Best Regards
Sarfraz

  • Thank you for the quick response. My apologies, I am using cadence 6.1 and MMSIM 11.1. So just to verify for this version when I run PNOISE, noise type ->modulated. PM = DSB, AM =DSB, LSB = SSB, USB = SSB? Therefore, if I'm interested in SSB PM the results I see are actually 3db higher than they should be? Thank you for the help.
