Abstract :
We introduce an optimized Josephson double array generating two independent voltages up to 1.5V using only one microwave input. Such an array, combined with the quantum Hall resistance, can provide the basic traceability for an electricity metrology laboratory from DC voltage to capacitance. We describe the array and present preliminary experimental results from DC measurements. Extending the output voltage up to 10V is discussed
