A 3-Input all Magnetic Full Adder with Misalignment-Free Clocking Mechanism

The clocking field misalignment is a critical issue for the application of Magnetic Quantum-dot Cellular Automata (MQCA). Recent work demonstrates a novel architecture to address this issue— by progressively tuning the shape anisotropy, we could enforce a misalignment-free signal propagation and logic operation. In this paper, we propose a novel architecture of a 3-input full adder based on the 45°-clocking field mechanism. The effectiveness of this design is confirmed through both simulation and experiments. Our work paves the way for the application of MQCA logic.
