Double-stacked Nb junctions with NbxSi1-x barriers were inserted into previously successfully tested 1 V and 10 V designs for Programmable Josephson voltage standards (PJVSs) with bias frequency near 70 GHz. Despite non-optimum targeting of the junction electrical parameters, comparison of the two circuits allows evaluation and optimization of the 10 V circuit design.
