By their very nature, spin waves (SWs) with different frequencies can propagate through the same waveguide, while mostly interfering own species. Therefore, more SW encoded data sets coexist, propagate, and interact in parallel, which opens road toward hardware replication-free parallel processing. In this article, we take advantage of these features propose a novel SW-based computing approach....

   This paper presents a novel design of quaternary logic gates using graphene nanoribbon field effect transistors (GNRFETs). GNRFETs are the alternative devices for digital circuit design due to their superior carrier-transport properties and potential for large-scale processing. In addition, Multiple-valued logic (MVL) is a promising alternative to the conventional binary logic design. Sa...

Successful operation of a quantum computer will require unprecedented control of quantum systems. The basic qubit operations, quantum logic gates, are described by the linear Schrodinger equation: the “analog” nature of quantum state evolution makes these logic gates fundamentally sensitive to imperfections in control and loss of energy. In contrast, conventional digital logic can correct error...

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...

Threshold gates consisting of resonant tunneling diodes (RTDs) in conjunction with HBTs or CHFETs or MOSFETs can form extremely compact, ultrafast, digital logic alternatives, and may be used for digital signal processing applications in the near future. The resonant tunneling phenomenon causes these circuits to exhibit super-high-speed switching capabilities. Additionally, by virtue of being t...

Polymorphic gates are unconventional logic components which can switch their logic functions according to changing environment. The first part of this study presents an evolutionary approach to the design of polymorphic modules which exhibit different logic functions in different environments. The most complicated circuit that we evolved contains more than 100 gates. The second part of this stu...

Abstract— In this paper, the researchers propose the design of reversible circuits using reversible gates. Reversible logic is implemented in reversible circuits. Reversible logic is mostly preferred due to less heat dissipation. Conservative logic gates can be designed in any sequential circuits and can be tested using two test vectors. The significance of proposed work lies in the design of r...

Wired-Logic is especially useful when designing fan-in restricted logic circuits which are implemented with bipolar and MOS transistors. However, there are few papers about logic design with Wired-Logic except the paper of the authors. In this paper, a method which reduces the levels of circuits by utilizing Wired-Logic is presented. The method restricts the number of fan-ins of a gate utilizin...
