Table 1
The comparison between our proposed designs and the best previous designs.
| | QCA full adders | Layer’s number | Complexity (cells) | Area (m2) | Latency (clk cycle) |
| | Coplanar QCA FA [8] | 1 | 145 | 0.17 | 1.25 | | Proposed QCA FA in Figure 8 | 1 | 104 | 0.13 | 1 | | Multilayer QCA FA [6] | 3 | 79 | 0.05 | 1.25 | | Proposed QCA FA in Figure 10 | 3 | 63 | 0.05 | 0.75 |
