Ramp ADC Bug Video

Deyan Levski, University of Oxford, UK, publishes a companion video to his IISW 2017 paper "A 12-bit Column-Parallel Flash TDC-Interpolated Ramp ADC with Online Digital Delay Element Correction" explaining a bug causing a larger than expected DNL in the ADC - quite a rare, possibly unique, video where an original designer explains his own bugs:

  2. What an honor to see this here! Should I have known I would have done a better and shorter demo. This link appeared on the last slide of the IISW presentation and intended to elaborate on the DNL glitching on every 16th code, as the 9-minute presentation slot was not enough for this.

    Anyway, thanks Vladimir for posting it.
