Abstract :
We are developing MoSi2-barrier stacked-junction arrays for Josephson voltage standards in order to increase the output voltage, operating bandwidth, and operating margins. In this paper we present measurements of a programmable voltage standard circuit with double-stacked arrays, where two junctions are fabricated in each stack. Although a mask defect prevented operation of one-eighth of the fabricated junctions, the remaining circuit, with a total of 51,344 junctions, succeeded in producing an output of 1.93 V with a range of operating current greater than 1 mA for the combined 13 subarrays
