Poll result: What parameters should be mandatory in ADC papers?

Poll: What ADC parameters should be mandatory in ADC implementation papers?

Back in July 2011, I raised the question “What parameters should be reported in a good ADC paper?”, and I also asked you what parameters you felt should be mandatory to report in ADC implementation type of papers, when applicable. The poll has been simmering for a while now, and your verdict as of May 28, 2012 is shown above.

Sampling rate (or bandwidth) is the parameter that most of the voters felt should be mandatory to report, closely followed by signal-to-noise-and-distortion ratio (SNDR). I kind of expected these two to come out on top. The lowest ranking parameters in this poll are effective resolution bandwidth (ERBW), self-noise, and intermodulation distortion (IMD).

There are some results that surprised me: I didn’t expect to see the low interest in nominal ADC resolution (N) and power dissipation (P). Only half of the voters want to require authors to report power dissipation, and as little as one third (!) wish to enforce the reporting of nominal resolution when applicable. Interesting, indeed.

What do you say? Are these results expected? Does the ranking list match your personal parameter preferences as well? Are your top two parameters also fs and SNDR (ENOB)?

I’ll keep the poll active, so if you want to have a say too, just make your choices below.

  2. Hello,

    The one thing I would mention is that when they publish graphs showing the FFT, they don’t normalize the plots. That way we can see how linear it is for a given input voltage. It is not fair to show good linearity while at the same time not knowing what the input voltage was.


    • Yes, it should be mandatory to report the input magnitude in dBFS or absolute voltage/current, and always together with the full-scale range in absolute voltage/current. The latter is valuable also for other assessments, such as putting the relative noise levels (SNR) in relation to the absolute swing/headroom.
