Abstract :
The programmable Josephson voltage standard combined with additional variable current source is proposed to be used as an ideal reference source. A stable reference source with sufficient current capability is required for low resistance ratio measurement, for example. Owing to the large Shapiro step of the PJVS array, a simple current source easily available with medium stability is sufficient for this purpose. Experimental result will also be presented to support the proposed idea
