i want to put a dc input on a switched capacitor integrator how can i do this

second i make a sigma delta modulator and iwant to put the dac in the integrator and make the feed back bits to control the switches how can i do this

Welcome to the PF.

What is the application? Is this for schoolwork?

Sounds like fun. I've moved the thread to the Homework Help, Engineering forum, which is where it belongs.

Now, can you please define some terms that you are using? At least to me, the terms are a bit off (it could be part of the language translation, or just a misunderstanding on my part or your part of the technical terms). Please write a bit about these:

** "a switched capacitor integrator"

** "a sigma delta modulator"

Once you define these a bit better, we may be able to offer some hints or pointers to sources of information to help you with your projects.
