Background and Objectives: Recently, photonic crystals have been considered as the basic structures for the realization of various optical devices for high speed optical communication. Methods: In this research, two dimensional photonic crystals are used for designing all optical logic gates. A photonic crystal structure with a triangular lattice is proposed for making NAND, XNOR, and OR optica...

Through technology development, VLSI fabrication is becoming smaller in size which causes much sensitivity of VLSI circuit to noise effects especially soft error. In this paper, we present a method to mitigate soft error in combinational logic gates based on 65 nm technology that is able to reduce the possibility of noise propagation in combinational logic gate. We evaluate our result based on ...

In low-voltage and low-power applications, optimization of several devices for speed and power is a significant issue. These issues can be overcome by incorporating Modified Gate Diffusion Input (Mod-GDI) technique. This technique has been adopted from Gate Diffusion Input (GDI). The Mod-GDI technique allows reducing power consumption, delay and area of digital circuits, while maintaining low c...

In this paper, a new high-speed circuit technique called differential cascode voltage switch with pass-gate (DCVSPG) logic tree is presented. The circuit technique is designed using a pass-gate logic tree in DCVSPG instead of the nMOS logic tree in the conventional DCVS circuit, which eliminates the floating node problem. By eliminating the floating node problem, the DCVSPG becomes a new type o...

Nanoscale skyrmions enable ultralow-power nonvolatile logic gate designs due to their current-driven motion and topological protection. A key building block in skyrmion-based digital spintronics is the inverter (not) gate. Despite recent computational practical demonstrations, a low-power, wideband, cascadable still long way off. For circuits, systematic design analysis of an essential. Here we...

Reversible logic has attracted significant attention in recent years. It has applications in low power CMOS, quantum computing, nanotechnology, and optical computing. Traditional gates such as AND, OR, and EXOR are not reversible. In fact NOT is the only reversible gate from the traditional set of gates. Several reversible gates have been proposed. Among them are the controlled NOT (also known ...
