Abstract

We present experimental results on new programmable Josephson voltage standards based on frequency dependently damped superconductor-insulator-superconductor (SIS) junctions. We introduce a design able to generate two independent floating voltages up to 1.5 V using a microwave frequency of 70 GHz. The array is developed for dc and ac voltage and impedance metrology. The design is optimized in terms of speed, power consumption, and stability. Stimulated power generation is shown to affect the performance of long SIS arrays. The collective dynamics of Josephson junctions is analyzed and a boundary condition for the design of long arrays is derived.
