Özet
© 2014 Allerton Press, Inc.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 S8/15(R Sis the shunt resistance, and R Nis 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.
