Abstract
In this study we carried out the analysis of the sensitivity of balanced comparators based on small Josephson junction. An expression was obtained for sensitivity in the case of linear growing strobe-pulse of voltage, and it was shown that, sensitivity is determined by the energy ratio-parameter of small size Josephson junction, temperature and sampling rate of comparator. Estimation gives the sensitivity at the level of nV.
