Memristor-based redundant binary adder

This paper introduces a memristor based redundant binary adder for canonic signed digit code, that coding eliminates the carry and provides a carry-free addition. The proposed binary adder circuit tries to achieve high addition speed that is independent on the length of the data using the accumulation property of a Nano-element called a memristor. The general block diagram of the proposed circuit is illustrated based on memristors and its operation has been validated using HP memristor model and simulated via different examples using PSPICE showing a great match.
