Brief Study of Noise-Shaping SAR ADC – Part B

In the previous post, I’ve shared some basics of sigma-delta ADC. In this post, before we look at the noise-shaping SAR ADC, let’s again do a warm-up. The z-domain linear model for a 1st-order sigma-delta modulator: The linear model has … Continue reading
