Аннотация:A balanced current comparator based on high-T-c bicrystal Josephson junctions has been designed, fabricated, and experimentally tested, The operation of the balanced comparator has been demonstrated in the temperature range from 4.2 to 70 K. The correct sequence of switching of the Josephson junctions has been determined by de measurements for different values of operating frequency and signal current l(x). The threshold uncertainty Delta I-x of the balanced comparator, measured at 40 K, was 60 mu A at 40 GHz and 300 mu A at 240 GHz
