Microwave-driven Josephson junction arrays are the basis for dc and ac voltage standards, whose accuracy derives from quantized voltage pulses. These pulses are also used to synthesize voltage-noise reference signals that are used in noise thermometry systems. This article describes our recent demonstration of voltage synthesis in a high-transition-temperature YBa2Cu3O7-δjunction circuit.
