Abstract

A programmable Josephson voltage standard chip using arrays of NbN/TiN/NbN/TiN/NbN double-junction stacks was fabricated and operated at 10 K. The circuit with over 260 000 junctions showed constant voltage steps at '}6V when driven with 11 GHz microwave bias. Further investigation is required to achieve 10 V operation at the desired 19 GHz design frequency.
