Optimization of Superconducting Microstrip Interconnects for Rapid Single-Flux-Quantum Circuits

Artikel i vetenskaplig tidskrift, 2005

In this paper, the issues related to the optimization of superconducting passive interconnects are discussed. The results of the microwave optimization of bends, vias connections and crossings of the superconducting microstrip lines (SMSL) are reported. The optimum design of the SMSL cross gives more than 95% of transmission and can be well used in two busses cross design with up to 14 signal wires. The results have been confirmed by time-domain simulations and measurements.
