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.
