Abstract

The output voltage of Programmable Josephson Voltage Standard (PJVS) circuits has reached the 10 V benchmark, which was set over twenty years ago by conventional dc Josephson Voltage Standard (JVS) systems. The nonhysteretic Josephson junctions in these next-generation 10 V PJVS systems enable a number of advantages and additional features as compared with JVS systems. Most importantly, the new PJVS system will have comprehensive Turnkey automation and be able to fully characterize all operating margins of the device without operator participation. Inherent voltage-step stability and large current margins (1 mA), which eliminate the need for output filters, will enable new applications not previously possible with conventional JVS. Rapid settling time (200 ns) will enable the generation of both DC and stepwise-approximated AC voltages that will be metrologically useful up to a few hundred hertz. The lower microwave drive frequency (20 GHz instead of 75 GHz) will reduce cost and improve reliability of the system.
