Hello,I am trying to figure out the development shown bellow of the SIGMA DELTA ADC transfer function. However the definition of Vref, and Vint are the same except the time if n-1 instead of n. very non imtuitive explanation. I cant find anywhere in the internet a similar switch capacitance implementation. Is there some anternative source of switch capacitor i can follow its development?
Thanks.

Hello there :)
Since a sigma-delta modulator loop is non-linear and
complex to analyze, the behavioral study of the system and
its effect of circuit non-idealities can be done using
SIMULINK® and MATLAB® model simulation.
