Abstract

Implementation of programmable Josephson voltage standard (PJVS) circuits on cryocooler at 4 K is a challenge. The limited cooling power of the cryocoolers has to balance the heat dissipated by the PJVS circuit in order to maintain a stable temperature. Flat-spot measurements of various quantized voltages produced with all of the sub-arrays of the PJVS circuit current biased and operating at a temperature of 4.3 K produced a step width of 1.32 mA. This result was obtained with a cryostat that uses a 3 kW water-cooled compressor that generates about 270 mW of cooling power at the chip for this temperature.
