I am trying to model a delta sigma ADC model for ADS131A04. I am using the existing model in MATLAB https://in.mathworks.com/help/physmod/sps/examples/delta-sigma-adc-with-noise.html. Now I have to modify the model as per my ADC. I want the information on how to set Vref, Clock, Tsim, Fs, Integrator block in demodulator block.

Hello Siva,
You can set Fs based on your sampling rate and clock is determined by Fs. Your reference voltage is based on your range of input. However, you may need to modify the simple example circuit you are looking at to support both positive and negative input values. Tsim is 1/Fs/10. The integrator block does not need changed as it operates based on Fs.
Regards,
Joel
