I know just ideal simulation (Z domain) for delat-sigma modulator by using Simulink/MATLab. But I want to know hot to include nonideal parameters (say opeamp gain, bandwidth, clock jitters, etc) for the system level simulation in Simulink/Matlab. Does anyone give me an adivece/ Does anyone know papers or reports about that? Any help is highly appreciated.
"mathematical transfer function" means z-domain function, right?
I am wondering how z-tansfer function (i.e. 1/z-1 for an integrator) chages by nonlinearity parameters???
sampling jitter sounds easy to understand (thanks to Markty!)
Thanks to all, too

The Details is on another paper by the same authors in JSSC.
I guess, I dont understand the simulink stuff.
it could really be useful to me, atleast for my thesis. so...
Can any person help me start the simulink with any simple examples? please upload or send to me via email.

This is a very good paper for delta/sigma ADC designers and it's exactly what I wanted know. Very very helpful.
Thanks a lot to everyone, especially zmliu!!
