Abstract

We have simulated and Laid out a Single Flux Quantum(SFQ) AND gate for Arithmetic Logic Unit by using XIC, WRspice and Lmeter. This circuit is a combination of two D Flip-Flop. D Flip- Flop and dc SQUID are the similar shape from the fact that it has the a loop inductor and two Josephson junction. We also obtained operating margins and accomplished layout of the AND gate. We got the margin of $\pm$42% over.
