Title: Sigma delta model validation
Post by cdbular on Apr 30^th, 2008, 11:47am

Do you know of any study or paper about sigma delta modulation models that includes correlation between noise sources.
How can I validate a model i am working on?
Thanks in advance

Which correlations do you want to implement?

We did some models for sigma-delta modulators, but didn't take into account correlating noise sources

Regards,

Stefan

In the model I am using has jitter noise and thermal noise from the OTA and from the switches resistances of the SC ingtegrator. I am triying to fing correlations beetween those noise sources.
