Inductive Voltage Divider Ratio Measurement Based on Dual-Channel PJVS

This paper introduces a dual-channel quantum voltage synthesis system based on Josephson junction. And two AC quantum voltage signals with adjustable amplitude and phase are synthesized. A method is introduced to measure the ratio and phase difference of an inductive voltage divider based on the dual-channel AC quantum voltage system. It is proved that the ratio and phase difference of a inductive voltage divider can be traced to Josephson quantum voltage by precision comparison experiment with self-calibration method.
