Abstract(in English) To achieve high-speed operation of high-temperature superconductive single-flux-quantum (SFQ) circuit, we designed two basic circuits, i.e. through circuit and ring oscillator. In the present study, multi-layered structure including a grand plane was assumed. Stable operation of the through circuit was confirmed up to 30K based on the circuit simulation, that is taking into account the thermal noise. Using the same technique, we confirmed 80GHz operation of the ring-oscillator at the temperature of 30K as well. Moreover, it was found that the duration time of the SFQ pulse is 0.4ps-0.7ps and the characteristics of the SFQ pulse degrade above 40K.
