Hi all.
I am investigating some properties of SD modulators and i would like to find some analytical equations for output spectrum of second order SD modulator as a function of input DC voltage.
If anyone can advice me some source (a book or an article) i will be thankful. :)
Alex.

I'm not sure if there exists a strict analytical expression for the output spectrum of an SDM. In my opinion the best sources of information on the subject are:
R.Schreier, G.Temes "Understanding Delta-Sigma Data Converters", IEEE Press
"Data Converters: Theory, Design, and Simulation", Ed. by S.R.Norsworthy, R.Schreier, G.C.Temes. IEEE Press, 1997
