Reversible computing has been studied since Rolf Landauer advanced the argument that has come to be known as Landauer's principle. This principle states that there is no minimum energy dissipation for logic operations in reversible computing, because it is not accompanied by reductions in information entropy. However, until now, no practical reversible logic gates have been demonstrated. One of...

How to reconfigure a logic gate for a variety of functions is an interesting topic. In this paper, a different method of designing logic gates are proposed. Initially, due to the training ability of the multilayer perceptron neural network, it was used to create a new type of logic and full adder gates. In this method, the perceptron network was trained and then tested. This network was 100% ac...

A novel low power and Positive Feedback Adiabatic Logic (PFAL) 5-input OR Gate is presented in this paper. The power consumption and general characteristics of the PFAL 5 input OR gate are then compared against two low power 5-input OR Gate; Efficient Charge Recovery Logic (ECRL), Conventional CMOS 5-input OR Gate. The proposed PFAL 5-input OR Gate design was proven to be superior to the other ...

A classical logic gate connecting input and output light pulses is demonstrated. The gate operation is based on three steps: First, two incoming light pulses are stored in a Bose-Einstein condensate; second, atomic four-wave mixing generates a new matter wave; and third, the light pulses are retrieved. In the presence of the new matter wave, the retrieval generates a new optical wave. The latte...

Logic gate nanoparticles, where two chemical transformations take place one after the other, were successfully formulated from a newly synthesized random co-polymer. This polymer, poly([2,2'-(propane-2,2-diylbis(oxy))bis(ethane-2,1-diyl) diacrylate ]-co-[hexane-1,6-diyl diacrylate]-4,4' trimethylene dipiperidine), (poly-β-aminoester ketal-2) contains two pH responsive moieties within its backbo...

The influence of gate direct tunneling current on ultrathin gate oxide MOS ( nm nm, – nm) circuits has been studied based on detailed simulations. For the gate oxide thickness down to 1.1 nm, gate direct tunneling currents, including the edge direct tunneling (EDT), show only a minor impact on low static-logic circuits. However, dynamic logic and analog circuits are more significantly influence...

As an emerging technology, Quantum-dot Cellular Automata (QCA) has been extensively analyzed in the technical literature for implementing logic circuits; in this technology, the basic combinational circuit is the majority voter with three inputs. In this paper, the design of a logic gate which implements any combinational function of at most three input variables is presented. This type of gate...

Reducing the ever-growing leakage current is critical to high performance and power efficient designs. We present an in-depth study of high-level leakage modeling and reduction in the context of a full custom design environment. We propose a methodology to estimate the circuit area, minimum and maximum leakage current, and maximum power-up current, introduced by leakage reduction using sleep tr...

In this paper, a formal design approach for the differential cascode voltage switch with pass gate (DCVSPG) logic is presented. This permits the design of any combinational logic function by the use of a k-map or by a modified QuineMcCluskey algorithm. The basic design approach used is based on pass logic and shows that a DCVSPG logic gate designed with minimum number of transistors may not alw...

The ternary Quantum-dot Cellular Automata (tQCA) were demonstrated to be a possible candidate for the implementation of a future multi-valued processing platform. Recent papers show that the application of the adiabatic pipelining can be used to solve the issues of the tQCA logic primitives. The architectures of the resulting tQCAs become similar to their binary counterparts and the physical de...
