AbstructQuantum-dot cellular automata (QCA) has been proposed as a replacement for CMOS circuits. The major difference between QCA and CMOS is that electronic charge, not current, is the information carrier. A complete set of logic gates has been created and some have been experimentally tested with metal-dots acting as quantum dots. Molecular implementations are currently being examined. This ...

We discuss novel nanoelectronic architecture paradigms based on cells composed of coupled quantum-dots. Boolean logic functions may be implemented in specific arrays of cells representing binary information, the so-called Quantum-Dot Cellular Automata (QCA). Cells may also be viewed as carrying analog information and we outline a network-theoretic description of such Quantum-Dot Nonlinear Netwo...

Restoring and non-restoring divider has become widely applicability in the era of digital computing application due to its computation speed. In this paper, we have proposed the design of divider of different architecture for the computation of Vedic sutra based. The design of divider in the Vedic mode results in high computation throughput due to its replica architecture, where latency is mini...
