Figure 8: Pattern generator. (a) Schematic for 1111, 1101, 0011, and 0000 generators; (b) QCA layout for 1111 generator (this QCA layout can generate other patterns by changing the standard pattern to 1101, 0011, or 0000); (c) simulation result for 1111 (15), 1101 (13), 0011 , and 0000 (0) generators.
