A 3-input all magnetic full adder with misalignment-free clocking mechanism
Zheng Li, Kannan M. Krishnan · Journal of Applied Physics · 2017
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.
