Title: Development and investigation of intrinsically shunted junction series arrays for ac Josephson voltage standards
Published: June 13, 2010
Abstract: Different types of intrinsically shunted Josephson junctions have been developed and inves¬tigated for ac voltage standard applications at PTB. The first type for generation of voltages up to 10 V is driven by a 70 GHz sinusoidal microwave signal and consists of 69,632 series-connected junctions, where the number of junctions per segment follows a binary sequence. The second type, which is driven by short current pulses, contains up to 5,000 junctions and enables the synthesis of intrinsically accurate ac waveforms.
