ABSTRACT
Calculations of the shape and the timing of single-magnetic-flux quanta (SFQs) generated by high-current-density "self-shunted" Josephson junctions are presented. The junction current is assumed to be due in part to multiple Andreev reflections within the high-transparency barrier. The SFQ pulses from these junctions show several differences when compared to those from lower-current-density resistively shunted Josephson junctions, the most important being that the pulses are significantly delayed in the self-shunted junctions, by as much as many times the pulse width. © 2001 American Institute of Physics.
