Quantum Dot Cellular Automata (QCA) provides a new structure for designing digital circuits with smaller size and less power consumption. This technology is a new method to implement digital circuits in the future. This paper presents a new rising edge triggered D flip-flop structure with reset capability. Simulation of the circuit in QCADesigner software confirms the correct operation of the circuit. Finally, several common structures without reset ability are compared with the proposed structure and the results are indicated in the comparison table. The designed D flip-flop uses 95 cells for implementation and will function properly in one period of time.
