A test bench has been developed for systematic char- acterization of high-resolution analog-to-digital converters. The reference signal is generated by a programable Josephson voltage standard. Three 24-bit digitizers have been characterized. Noise performance has been measured at direct current using the Allan deviation, whereas integral nonlinearity has been measured with quasi-dynamic stepwise triangular waveforms at frequencies be- tween 0.5 Hz and 1 kHz. None of the digitizers outperforms all others for each tested characteristics. Therefore, such a systematic characterization provides the overview needed to identify the most suitable digitizer for a given application.

    • ...An exhaustive analysis of the resolution, the gain, the stability, and the integral nonlinearities (INL) is described in [13]...
    • ...Finally, to minimize the effects of the remaining digitizer nonlinearities, the amplitude of the PJVS waveform is adjusted to obtain a measured amplitude ratio r as close as possible to r =1 . Due to the slightly larger distortion observed close to full scale [13], the digitizer voltage range is selected to be at least four times larger than the waveform amplitude...
