The cellular automaton with quantum dots, is a branch of nanotechnology, can be used to create combinational and sequential circuits at the nanoscale, by manipulating the position of the electron. In comparison to existing transistor-based SR,JK T, and D flip-flops, QCA technology offers a number of additional benefits, including low power consumption, faster speed, small size, and great performance. When compared to a single edge triggered QCA circuit, the dual edge triggered QCA structure offers minimal power consumption and fast switching. The primary design criteria for circuits include cell count, and area usage, [9] to compare the two edges triggered flip-flops with the one edge -triggered flip-flops, we create both types of flip-flops in this work.
