A spectrum of the signal and the flat noise from DC to fs/2 in Figures 2 and 3 shows that the noise can be filtered to fs/(2•OSR) to improve the dynamic range and SNR. In this case, the oversampled ...
Delta-sigma modulation has emerged as a pivotal technique in CMOS technology for high-resolution analogue‐to‐digital conversion. By utilising oversampling and noise-shaping strategies, this method ...
In my previous blog, Which Is Better: SAR or Delta-Sigma ADCs?, I gave an overview of the delta-sigma and SAR (successive approximation register) ADCs. I discussed the technique of oversampling as it ...
