    How to create a delta-sigma modulator in PSoC Creator

    peli.fidelman

       Hi,

         

      I need to create a delta-sigma modulator for a signal that isn't necessarily positive, for example lets say that the signal is in the range (-1,1)[V].  

         

      I'll need an option to reset the modulator between different conversions.

         

      This project is for a PSoC 5 architecture.

         

      I noticed that there are analog primitives in PSoC creator. two of which can be relevant:

         

      1. ds_mod (DS Modulator).

         

      2. scblock.

         

      neither of them has a data sheet so I'm not sure how to use them. 

         

      Any Ideas which is best to use and how to define it correctly? 

         

      Attach is a screenshot of the primitives.

         

      Thanks,
