Abstract
A complex single flux quantum(SFQ) circuit could be made up of various elementary cells such as JTL(Josephson transmission line), Splitter, XOR, DC/SFQ, SFQ/DC, T flip-flop, ‥‥, etc. In this work, we have designed and simulated a SFQ circuit, which consists of DC/SFQ, JTL and SFQ/DC, based on Nb/AlO$_{x}$Nb Josephson junction technology From the simulation, we could obtain the margins for various circuit parameters. And also we have successfully operated the circuit, which was fabricated with the same design, up to the input signal frequency of about 20 GHz.z.
