High performance NOT, NAND and NOR logic gates composed of GaAs-nanowire (NW)-based metal-semiconductor field-effect transistors (MESFETs) were constructed on flexible plastics through a noble top-down route. The representative GaAs-NW-based MESFETs exhibited superior electrical characteristics such as a high mobility (∼3300 cm(2) V(-) s(-1)), large I(on)/I(off) ratio (∼10(8)) and small subthre...

Abstract: Noise-based logic, by utilizing its multidimensional logic hyperspace, has significant potential for low-power parallel operations in beyond-Moore-chips. However universal gates for Boolean logic thus far had to rely on either time averaging to distinguish signals from each other or, alternatively, on squeezed logic signals, where the logic-high was represented by a random process and...

A nonclassical multi-valued logic based on Post algebra is presented. Besides the conventional Post's cyclic negation, this nonclassical logic algebra defines new operators that simplify the truth-table minimization techniques. An electronic implementation of this algebra for a 3-level logic is proposed. Electronics gates of Post negation and the new operators were designed and simulated using ...

We present a new lower bound on the number of gates in reversible logic circuits that represent a given reversible logic function, in which the circuits are assumed to consist of general Toffoli gates and have no redundant input/output lines. We make a theoretical comparison of lower bounds, and prove that the proposed bound is better than the previous one. Moreover, experimental results for lo...

Logic gates are basic digital elements for computers. We build up thermal logic gates that can perform similar operations as their electronic counterparts. The thermal logic gates are based on nonlinear lattices, which exhibit very intriguing phenomena due to their temperature dependent power spectra. We demonstrate that phonons, the heat carriers, can also be used to carry information and proc...

The predicate logic gates are proposed for spatially modulated signals. Two voltage impulses are transmitted along the coupled wires, and they are considered as a predicate expression. The developed gates perform the logical operations AND, NOT and OR with these expressions. They are used for a predicate logic microprocessor. Key-Words: Artificial spatial intelligence, predicate logic, topologi...

MOS current mode logic (MCML) is an emerging logic family which is gaining attention due to its high speed of operation, robust performance and presence of mere switching noise as compared to the CMOS logic family. In this paper we have compared universal gates using MCML and conventional CMOS in terms of power and propagation delay at 16-nm Technology node. Comparative analysis shows that MCML...

In recent past, reversible logic is emerged as a promising computing paradigm with applications in low-power CMOS, quantum computing, optical computing and nanotechnology. Optical logic gates become potential component to work at macroscopic (light pulses carry information), or quantum (single photon carries information) levels with high efficiency. In this paper, we propose a novel scheme of T...

We also demonstrate the realization of the proposed gates using basic quantum quaternary operations. We then employ our synthesis method to desig...
