ABSTRACT

This chapter presents the theory and design of Lattice-based integrated-signal nanocellular automata (LINA) circuitry along with simulation results to verify its design. It describes the underlying theory and advantages of LINA. The chapter introduces logical structures and circuits. It presents design principles and simulation results. It offers a design example in which LINA is used. LINA is a lattice-based design that enables a mixture of self-assembly and patterning techniques to overcome deposition and/or positioning challenges and is flexible enough to incorporate error-prone fabrication and various clocking wire minimum pattern sizes. Added benefit of the LINA designs is the flexibility to adjust structure widths based on large-scale patterning technologies, thereby potentially allowing currently available patterning techniques to be used in LINA quantum-dot cellular automata (QCA) circuits. If the QCA paradigm is to compete as a suitable replacement for complementary metal oxide semiconductor (CMOS)-integrated circuitry in the coming years, implementation strategies for large-scale room-temperature operation must be developed.
