Direct measurement of standard cells with a Josephson junction array voltage standard

摘要

The dynamic parameters of standard cells in a circuit for the direct measurement of a standard cell with a Josephson junction array voltage standard were analysed. The parameters of the models of a null-detector and a standard cell were experimentally determined. It was found that it is possible to directly measure a standard cell with a voltage standard, with an uncertainty of about 0.001 ppm.
