hi everyone
I am trying to simulate a sigma delta in simulink. I need a block for a 1 bit dac, to give the modulator a feedback. Can anyone tell me how to get this DAC.
 

Use a comparator block then a saturation block which would be your Vrefp and Vrefm. I forget if the comparator block has saturation build in it or not...
Hope this helps
Jgk
