Dual-Frequency-Bias Programmable Josephson Voltage Standard Circuit

This paper presents a 2 V programmable Josephson voltage standard with dual microwave frequency inputs and multiple output taps. The design provides three main features: (1) output voltages with nanovolt resolution, (2) the ability to perform a microwave frequency self-check based on a null voltage measurement, and (3) additional voltage output taps providing simultaneous 10:1 (or 5:1) divided voltage reference for resistive divider calibration. With low heat dissipation this device is well suited for implementation with a compact cryocooler as a turnkey traveling system.
