Abstract
We present a new record output voltage of 275 mVrms, which is a 25% improvement over the maximum achieved with previous ac Josephson voltage standard circuits. We demonstrate operating margins for these circuits and use them to measure the harmonic distortion of a commercial digitizer. Having exceeded the threshold of 125 mVrms for a single array of Josephson junctions, we propose an 8-array circuit capable of achieving 1 Vrms.Proceedings Title
