Delta Sigma Modulator - Capacitor value

[tom.73545]

Hi all..

At the moment I am designing a first order delta sigma modulator. I would like to ask you regarding the value of the capacitor and resistor used in the integrator (the circuit used is op-amp with R in inverting input and C in the feedback network). Could someone share about this matter? Is there any different if I use op-amp with lower gain for the integrator?

Thanks in advance!

Thanks for the reference. Unfortunately I don't have that book, but I will see maybe it is available somehow online or in the library. Thanks once again.

This book is called as "Green Book".

The following is called as "Yellow Book".
Amazon.com: Delta-Sigma Data Converters: Theory, Design, and Simulation (9780780310452): Steven R. Norsworthy, Richard Schreier, Gabor C. Temes: Books

Both books are vary famous book on Delta-Sigma Modulation techniques.
You should have "Green Book" at least along with the following.
