Abstract :
We have developed an accurate synthesized voltage source for AC and DC metrology, based on the quantized pulses of Josephson junctions. We demonstrated this technique in experiments with arrays of junctions clocked at 6 Gbit/s and synthesized sine waves with millivolt amplitudes at frequencies up to 1 MHz.
