Ultimate performance of the RSFQ logic circuits

A new family of dc-powered Josephson junction digital devices, the Rapid Single Flux Quantum (RSFQ) logic, is described. The devices use overdamped Josephson junctions and two-junction interferometers to store, pass and process the digital information presented in form of single flux quanta. We have carried out extensive numerical simulation of the dynamics of the RSFQ logic gates and of some more complex circuits including serial full adder and reversible shift register, within the standard microscopic-theory ("Werthamer") description of Josephson junctions. The minimum clock cycles of the basic RSFQ circuits turn out to be as small as 2.5 ps. The most promising ways to use the RSFQ logic circuits at the present stage of development of the Josephson junction digital technology are discussed.

Design issues for interconnects in densely packaged RSFQ structures

The manufacturing process of LTS RSFQ circuits is quite similar to that of the semiconductor chips, thus providing the possibility of an ultra high-density packaging similar to the modern semiconductor logic circuits. However, the miniaturization of the interconnects does not enhance their performance. The present work highlights the impact of the parasitic interactions between the superconductive interconnects on the correct logical functionality and the upper bias current margins of the LTS RSFQ circuits.
