— Progress toward a Josephson voltage standard for fast dc measurements and accurate ac waveform synthesis is described. A superconductor-normal-superconductor (SNS) junction process is used to make 5 mA critical current arrays with up to 32 768 junctions. With rf excitation at 11 GHz these arrays generate milliampere constant-voltage steps. A bias control(More)
