Influence of anharmonic current-phase relation on the time resolution of Josephson balanced comparator

In this study, we carried out the analysis of the resolution time of Josephson junction (JJ) balanced comparators with anharmonic current-phase relation (CPR). An expression for the time resolution was obtained in the case of linearly growing strobe current pulse driven via the junction. It is shown that the resolution time of balanced comparators is improved by the renormalized critical current of JJ with anharmonic CPR.
