Dear all, if we tune the bit weight of a SAR ADC, would it only affect the error power contributed by the capacitor mismatch? In other words, I guess it won't change the error power contributed by the circuit noise. However, I have not found materials discussing this directly. Any suggestions to this matter would be highly appreciated, thanks!
Thank you for your reply. More specifically, when using LMS-based calibration methods, does the circuit noise affect the calibration results? Since the loop only aims to minimize the output mean-square-error, it may not tell whether or not this error comes from the circuit noise or the mismatch.
