Research Abstract

Single-flux-quantum (SFQ) integrated circuits, which combine SFQ circuits with loss-less superconducting passive transmission lines (PTLs), have extremely high-speed and low-power abilities. In this study, a technique to connect SFQ logic gates directly with PTLs was studied and a new cell library was developed. It was demonstrated that the junction number and power consumption of SFQ circuits were considerably reduced with this technique. FFT signal processors were also developed based on this technique for their digital-signal-processor application, and their high-speed operation was demonstrated.
