Pulse Generator of Asynchronous SAR ADC
When it comes to designing SAR ADC, I am like a tortoise and can never imagine the world of rabbits. Recently I got some time to ponder how the rabbits can run so fast. One of the critical factors is … Continue reading

Memos on FFT With Windowing
Coherent sampling is quite difficult to meet under the lab conditions. One has to go for windowing to characterize the dynamic performance of ADC. Though seminal papers and reports [12] lie on my desk for quite long time, I still feel … Continue reading
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
Noise Effect On The Distribution of ADC Output Codes
In the previous post, the probability of comparator decision with the existence of noise was calculated. In this post, the topic about noise and probability will continue. The whole topic is actually inspired by a 1986paper [1], which discusses noise effect … Continue reading
Brief Study of Dither C: Dithered DNL
In ‘Dither’ series B, I have shown dither reduces the harmonic distortion by decolalizing the code mapping of the analog signal from the transfer curve. So if we take a step further, we might say the main purpose of dither is … Continue reading
