Implementation of a Crossbar Network Using Quantum-Dot Cellular Automata

Extendable Quantum-Dot Cellular Automata Decoding Architecture Using 5-Input Majority Gate

“…The clock phases can also summarized as Figure 6. [28] proposed a new wire-crossing technique (this is called a crossbar network) based on parallel to serial conversion and time-dependent latching in order to improve the disadvantages of the previous two techniques. The characteristic of this technique is that two wires are crossed in coplanar without the rotation or translation of cells, and structure of the cell arrangement is regular because of using the parallel to serial conversion method.…”

“…45 rotated cells induce the additional space between cells. It significantly decreases the energy separation between the ground state and the first excited state, which degrades the performance of such a device in terms of maximum operating temperature, resistance to entropy, and minimum switching time [12].…”

“…One of solutions is a quantum-dot cellular automata (QCA). It not only gives a solution at nano-scale, but also offers new techniques of computation and data transmission [6][7][8][9][10][11][12][13][14].…”

“…One solution even allows an arbitrary set of wire crossings, although it requires the use of several additional clock signals [22].…”

Low Hardware Complexity QCA Decoding Architecture Using Inverter Chain

“…45 rotated cells induce the additional space between cells. It significantly decreases the energy separation between the ground state and the first excited state, which degrades the performance of such a device in terms of maximum operating temperature, resistance to entropy, and minimum switching time [21]. Moreover, this is much easier to construct and has less noise than multilayered.…”
