摘要

Superconducting converters between RSFQ subsystems in the return-to-zero (RZ) mode and semiconductor electronics in the non-return-to-zero (NRZ) mode are conceived, simulated (SPICE, CADENCE) and optimized (ABAK) for data transmission at 10 GHz clock frequency and low power dissipation. An error correction scheme with a majority gate is used. RZ-to-NRZ converters with only 21 Josephson junctions are implemented with the 1 kA/cm~2 Niobium technology in Karlsruhe and tested successfully at 4.2 K and 500 MHz. Improvements in fabrication and instrumentation will enable measurements at microwave clock frequencies.
