Yes, Chalil, you are correct. You have calculated the SNR using Richard's Sigma-Delta Toolbox itself.However, if we implement the same modulator using the difference...

3rd Order CIFF Sigma Delta ADC

New thread started 3 weeks ago
Hello everyone,I'm trying to verify the theoretical SNR of a Conventional 3rd-order single-bit CIFF Sigma-Delta ADC with an OSR of 60. The feedforward and gain coefficients...

Okay got it, but I'm still observing that the output is starting from 0 instead of 0.3ms. Is this expected behavior in Sigma-Delta ADCs?When I apply a step input...
