Novel fault tolerant QCA circuits

摘要

In this paper we present a fault tolerant full adder cell as well as a fault tolerant serial adder circuit. It is worthwhile that this is the first time that a real fault tolerant full adder cell has been proposed. This is the very same for the fault tolerant serial adder cell. We have also generated a program to assess the fault tolerance. While the other full adder designs seem to be sensitive to fault, it seems that the proposed cells are much more fault tolerant.
