the full adders (fas) constitute the essential elements of digital systems, in a sense that they affect the circuit parameters of such systems. with respect to the mosfet restrictions, its replacement by new devices and technologies is inevitable. qca is one of the accomplishments in nanotechnology nominated as the candidate for mosfet replacement. in this article 4 new layouts are presented fo...

This paper proposes a full adder with minimum power consumption and lowloss with a central frequency of 1550nm using plasmonic Metal-Insulator-Metal (MIM)waveguide structure and rectangular cavity resonator. This full adder operates based onXOR and AND logic gates. In this full adder, the resonant wave composition of the firstand second modes has been used and we have ob...

A fast low-power 1-bit full adder circuit suitable for nano-scale CMOS implementation is presented. Out of the three modules in a common full-adder circuit, we have replaced one with a new design, and optimized another one, all with the goal to reduce the static power consumption. The design has been simulated and evaluated using the 65 nm PTM models.

   Quantum-dot Cellular Automata (QCA) technology is a solution for implementation of the nanometer sized circuits and it can be a suitable replacement for CMOS. Similar to CMOS technology, designing the basic computational element such as adder with the QCA technology is regarded as one of the most important issues that extensive researches have been done about it. In this paper, a new eff...

moving towards nanometer scales, quantum-dot cellular automata (qca) technology emerged as a novel solution, which can be a suitable replacement for complementary metal-oxide-semiconductor (cmos) technology. the 3-input majority function and inverter gate are fundamental gates in the qca technology, which all logical functions are produced based on them. like cmos technology, making the basic c...

In this paper, a full adder cell based on majority function using Carbon-Nanotube Field-Effect Transistor (CNFET) technology is presented. CNFETs possess considerable features that lead to their wide usage in digital circuits design. For the design of the cell input capacitors and inverters are used. These kinds of design method cause a high degree of regularity and simplicity. The proposed des...

In this paper, a new low-voltage low-power CMOS 1-bit full adder circuit is proposed. The proposed full adder can provide a full voltage swing at a low supply voltage and offers superior performance in both power and speed than the conventional full adder, the transmission full adder, and the recent low-voltage full adder. Based on the simulation results performed by HSPICE, the new low-voltage...
