Abstract

We have developed a programmable Josephson voltage standard based on an array of superconductor–insulator–superconductor junctions. The junctions are damped by an external frequency-dependent shunt circuit, which allows operation at Shapiro steps with n>1. We derive optimization criteria for the design parameters for a fast and stable array with low power consumption. An array able to generate 1.0 VRMS ac voltage signal with sub-ppm accuracy is experimentally demonstrated. Theoretically it is also shown that a fast programmable 10 V array can be realized.
