AQFP gate can decide the state by small input current, so AQFP circuit is expected to operate with large fan-out. Recently, test circuit of fan-out 4 AQFP splitter and 3 to 8 decoder (includes fan-out 8 splitter) correctly operated. In this study, we considered the interference between large fan-out splitters and other gates in simulation to achieve correct operation of fan-out 8 (or larger) splitters, and measured test circuit of splitters.
