| Research Abstract |
Quantum AC voltage standard has been researched, which is based on a single-flux-quantum (SFQ) digital-to-analog (D/A) converter and a high-precision inductive voltage divider (IVD). We have developed a reliable fabrication process for large-scale SFQ circuits. New modulation methods have been proposed and examined for higher accuracy of the output waveforms of the D/A converter. We have also developed an IVD system including filters with sufficiently high precision for the metrology applications.
