Abstract :
We present a pulse-driven asynchronous logic gate family based on a high-speed, low-power Josephson-junction device of rapid single-flux-quantum (RSFQ) circuits. Dual-rail logic is used and clock-free operation is realized. The proper operation of the circuits is confirmed by the numerical simulation which shows logic delays are about 60 ps for an AND and about 80 ps for an XOR. Power consumption is estimated to be 10 μW/gate
