Quantum-dot Cellular Automata (QCA) is a new emerging technology for designing electronic circuits in nanoscale. QCA technology comes to overcome the CMOS limitation and to be a good alternative as it can work in ultra-high-speed. QCA brought researchers attention due to many features such as low power consumption, small feature size in addition to high frequency. Designing circuits in QCA technology with minimum costs such as cells count and the area is very important. This paper presents novel structures of D-latch and D-Flip Flop with the lower area and cell count. The proposed Flip-Flop has SET and RESET ability. The proposed latch and Flip-Flop have lower complexity compared with counterparts in terms of cell counts by 32% and 26% respectively. The proposed circuits are designed and simulated in QCADesigner software.

“…Some best relevant of such circuits are shown in Figure 7. In Figure 7(a) proposed by [20], the authors proposed D flip-flop without set/reset ability where D flip-flop having the ability to set and reset the output is proposed in [21] as shown in Figure 7(b). In Figure 7(c), the design reported in [22] is shown with better performance.…”

Quantum-Dot Cellular Automata (QCA) is a transistor-less technology. In QCA, Columbic repulsion between electrons in the quantum dots makes data transfer possible. This paper presents the design of flip flops using a proposed Rotated-Normal Cells with Displacement (RND) inverter and a cell interaction method. The SR latch, SR Flip Flop (FF), D FF, and T FF are developed using QCA. The proposed D FF gives total and average energy dissipation of 1.31e-002eV and 1.19e-003eV respectively. It also gives a delay of 1 clock phase. The Proposed T FF provides total and average energy dissipation of 2.40e-002eV and 2.18e-003eV respectively, depicting efficient D FF and T FF in energy dissipation. The proposed SR Flip flop design gives an efficient area. The FFs with the proposed RND inverter and cell interaction method can be the best choice for future Nano communication to construct Nano circuits with less energy dissipation and high speed.
