A New Method for Designing QCA Circuits

Free registration required

Executive Summary

In this paper, the authors tried to solve some of the problems in logical designing based on Quantum-dot Cellular Automata (QCA) technology especially by using Null Convention Logic (NCL) instead of traditional Boolean logic and design circuits by using Locally Synchronous Globally Asynchronous (LSGA) method, and solve the problem of using feedback inside the QCA gates in this method, by design the gates that haven't any feedback. By this proposed method and designed gates the authors can design and build logical circuits based on QCA technology that may have fewer error rates.
