Abstract
In this paper, the time resolution of Josephson balanced comparators with shunt resistance is theoretically estimated. A general expression is obtained for the time resolution of the linearly growing strobe pulse. It is shown that the time resolution deteriorates by a factor of (1+2R N /R S 8/15 (R S is the shunt resistance, and R N is the normal resistance of the Josephson junction), while shunting improves the sensitivity of balanced comparators, as is proven in [20]. Estimates show that it is possible to reach subpicosec time resolution for balanced Josephson comparators with shunt resistance.
