dynamic range scaling in delta sigma modulator
Aug 05th, 2013, 9:06am  
Hi all,

For 5th order DSM design, I am using schreier's toolbox.
In that we have a function called scaleABCD.
I would like to know what does xlim stand for here.

Because in real circuit,we have vdd, refh,vcm and refl. How can I correlate the xlim Vs the variables mentioned above?

Thanks in advance.

hi there
guess you dont have the Schreier's textbook with you on ADCs
'Understanding delta sigma converters'

The explanation for this is given on the page 402.

xlim -->The limit on the states. May be given as a vector
