Design and Modeling of Digital Superconducting Logic Circuits

Abstract

The main objective of this research is to design a superconducting digital signal processor with low power and high-speed performance using RSFQ (Rapid Single Flux Quantum Logic) digital superconducting logic and digital RQL (Reciprocal Quantum Logic). Initially the basic superconducting gate operations are simulated and verified. Then the basic operations like 1 bit half adder, 2 bit full adder, counter and a CSA (Carry Save Adder) are designed using both digital RSFQ and the digital RQL superconducting logic newline
