Hi All,
I have been working on CT-DS ADC. It is a single bit quantizer.
From my understanding, say we take NRZ DAC in the feedback and we design the ADC for the DAC amplitude of 1 and DAC width of 1 such that the area of DAC is equal to 1. With the integrator say being 1/s and the sampling frequency is 1Hz, the integrated output of the integrator would ramp up to 1 and then become constant. The sampling at 1Hz would then give output as 0,1,1,1,.... as would be the case with the impulse response of
\frac{{z}^{ -1}}{1-{z}^{-1 } } .
Now, if I change my frequency of sampling from 1Hz to say fs, what all coefficients will I need to change and to what?
