Abstract:
We have developed and tested simple and inexpensive electronics for interfacing Rapid Single-Flux-Quantum (RSFQ) Josephson-junction circuits to room temperature digital systems. Voltage-level (Non-Return-to-Zero) bit signals with a swing of /spl sim/150 uV, developed on-chip by standard SFQ/DC converters, and in some cases amplified to 1.5 mV swing by HUFFLE-type circuits, are passed to the 300 K environment using a high density (40 channel) flexible coplanar waveguide assembly. AC-coupled, 2-3 stage microwave Si-bipolar amps, and Emitter-Coupled-Logic (ECL) buffers accomplish voltage level translation to the standard ECL levels, Using this technique, data rates in excess of 1 Gb/s per channel can be achieved at low cost per channel,.<>
