Abstract -
Nanotechnology based QCA basic logic layouts work well while simulating on QCA Designer software. The design of half adders has been reported by various researchers and most of the circuit combinations produce excellent results on simulation. Although design of QCA full adders has been reported by a large number of researchers but the simulation results on most of the circuits fail to produce claimed outputs as such the carry forward work is becoming difficult. There are certain difficulties in producing desired simulation results while joining two half adders to design full adder. The main cause for the problem seems to be the mismatch of input data, when earlier stage data is combined with the forward stage. We have tried to study some full adder designs on the basis of simulation results to move forward with our own designs for the purpose. With analysis of few reported adders we have proposed two full adder circuit layout designs with analysis for efficient implementation and future improvements.
