Abstract: Lot of research has been going on for implementing digital systems at nano-scale level. Quantum-dot based Quantum Cellular Automata (QCA) is a promising as well as emerging technology for implementing of digital systems at nano-scale. By taking full advantage of the unique feature of this technology, it is possible to have device which functions consuming ultra low power and very high operating speeds. In this work, we have selected few basic flip-flops and studied them well. Using the computational tools “QCA Designer” proposed for designing QCA based digital circuits; we have designed the QCA circuits of D-Flip Flop. The correctness of the proposed circuits is also verified using simulation results obtained using QCA Designer.
