| Abstract(in English) | We have been developing the adiabatic quantum-flux-parametron (AQFP) as an ultra-low-power superconductor logic. Latches, which store logic data in logic circuits, are indispensable components in the realization of AQFP digital computing systems. Among them, feedback latches, which hold data by using a feedback loop, have advantages in terms of their wide operation margins. Their drawbacks are their large junction counts and long latency. Therefore, we propose a majority gate-based feedback latch for AQFP logic with a reduced number of junctions. We designed and fabricated the proposed AQFP latches, and experimentally confirmed their correct operations. The measured operation margins agree well with the simulation results. |
