Hi,
I am trying to design a second-order incremental ADC, I am wondering how can I achieve that by adjusting the code mentioned in "UNDERSTANDING DELTA-SIGMA DATA CONVERTERS" (mainly the code starting from p.167) using the "delta sigma toolbox" in Matlab
Here is the block diagram for the design I am trying to build

I am just wondering, since there is a feed-forward and feedback loop, how would I "use" the toolbox to accommodate that?
Anyone who has designed this can walk me through how to find all those capacitor (ratio) values?
A brief walk-through of the toolbox will be super helpful, too!
Thanks a lot!
