Those ADC Literature Surveys

Posted on July 23, 2012 by Dai

Murmann’s ADC Performance Survey Recent ADC designers in the scientific world usually take Murmann’s Spreadsheet as a benchmark for their ADC performance. The survey  contains experimental data from two top conferences (ISSCC & VLSI Symposium) between 1997 and now (2012), … Continue reading →

ADC Performance B: INL vs. THD

Posted on March 28, 2012 by Dai

In the previous post, I’ve looked at the relation between DNL and SNR. In DNL plot, where the variation of the nonlinearity error just looks like noise, so it’s easy to imagine that the SNR will be degraded due to … Continue reading →

ADC Performance A : DNL vs. SNR

Posted on March 27, 2012 by Dai

Recently I pick up Wang Xiaobo‘s essays again. One sentence from him made a deep impression on me: do what you like is ‘have’; do what you don’t know why you are doing is ‘not have’. Then I came here … Continue reading →

Derive kT/C from Equipartition Theorem

Posted on February 20, 2012 by Dai

It’s better to know(actually have to know) kT/C if you design ADCs. First, let’s take a look at its inverse-derivation (for detailed explanation, please go for elsewhere, there are lots of…): Then, comes the dessert of today – Equipartition Theorem … Continue reading →

Noise Figure of ADC

Posted on November 23, 2011 by Dai

Recently, I’m studying some RF basics. When comes to the noise performance of a wireless system, noise figure (NF) is frequently used as a characterization term. It is defined as Noise figure is a measure of how much the signal-to-noise ratio … Continue reading →
