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 results of a programmable voltage standard circuit with double-stacked arrays, where two junctions are fabricated in each stack. Although a mask defect prevents operation of one-eighth of the fabricated junctions, the remaining circuit, with a total of 57 344 junctions, succeeded in producing 1.93V output with operating current range greater than 1mA for the combined 13 sub-arrays.
