Brief Study of NoiseShaping SAR ADC – Part C
The topic of noiseshaping SAR ADC will come to an end in this post. In Part A, I briefly talked about the concept of noise shaping applied to sigmadelta modulators. In Part B, I introduced one special property of SAR … Continue reading
Brief Study of NoiseShaping SAR ADC – Part B
In the previous post, I’ve shared some basics of sigmadelta ADC. In this post, before we look at the noiseshaping SAR ADC, let’s again do a warmup. The zdomain linear model for a 1storder sigmadelta modulator: The linear model has … Continue reading
Brief Study of NoiseShaping SAR ADC – Part A
Sometimes it is much easier to become a fan of something when you only know something about it. Just like SigmaDelta ADC, it is so complicated that even though I have learned it for several times I still can’t fully understand it! Nevertheless, I am … Continue reading
