Quantum-dot cellular automata (QCA) is a kind of nano-devices with special computing paradigm
which is one of powerful competitors to replace traditional CMOS devices in the future. Based on the power consumption model in QCA technology
the coupling strength between cells in coplanar systems is modeled for radius of 41nm. The QCA gate structure model is then constructed according to the locations of cells to classify existing coplanar five-input majority gates. By characterizing their performances
a new low-power five-input majority gate is proposed. Simulation results demonstrate that the proposed gate has lowest power consumption and performs better than other gates. To verify its properties in practical applications
a new coplanar QCA full adder is designed by means of MR Azghadi full adder
which has the best performance among similar adders.
