Abstract

In this paper, we introduce the Magnetic Quantum-dot Cellular Automata (MQCA) based area and speed efficient design approach for nanomagnetic full adder implementation. We exploited the physical properties of three input MQCA majority gate, where the fixed input of the majority gate is coupled ferromagnetically to one of the primary input operands. Subsequently, we propose a design methodology, mapping logic and micromagnetic software implementation, validation of the binary full adder architecture built using two-three inputs MQCA majority gates. In addition, we also analyzed our proposed design for switching errors to ensure bit stability and reliability. Our proposed design leads to 36% - 69% reduction in the number of nanomagnets, 50% - 75% reduction in the number of clock cycles and 33% - 50% reduction in the number of majority gate operations required for the binary full adder implementation compared to the state of art designs.
