Abstract :
A new method to compare the Quantized Hall Resistance (QHR) with a conventional resistance standard is proposed. This new method uses a Binary junction programmable Josephson array specifically designed to have a center tap to simultaneously measure the voltage of the QHR and the test resistance. This new method is expected to compete in uncertainty with the Cryogenic Current Comparator at lower cost.
