Abstract :
This paper describes the results of a preliminary analysis of ultra-fast low-power superconductor digital switches based on Rapid Single-Flux-Quantum (RSFQ) technology. In particular, RSFQ-based crossbar, Batcher-banyan, and shared bus switching cores have been considered, and the possible parameters of these circuits have been estimated. The results show that the proposed RSFQ digital switches with overall throughput of 7.5 Tbps operating at an internal clock frequency of /spl sim/60 GHz and dissipating very little power could effectively compete with their semiconductor and photonic counterparts.
