摘要：

A binary sequence of series arrays of shunted Josephson junctions is used to make a 14-b D/A converter. With 13 bias lines,any step number in the range -8192 to +8192 -1.2 V to +1.2 V can be selected in the time required to stabilize the bias current (a few microseconds). The circuit is a fast accurate de reference, and it makes possible the digital synthesis of ac waveforms whose amplitudes derive directly from the internationally accepted definition of the volt.
