Abstract

We have designed a SFQ (Single Flux Quantum) D2 Cell and Inverter(NOT) for a superconducting ALU (Arithmetic Logic Unit). To optimize the circuit, we have used Julia, XIC and Lmeter for simulations and layouts. We obtained the circuit margin of larger than $\pm$25%. After layout, we drew chip for fabrication of SFQ D2 Cell and Inverter. We connected D2 Cell and Inverter to jtl, DC/SFQ, SFQ/DC and RS flip-flop for measurement.
