About This repository contains VHDL implementations of basic logic gates (AND, OR, NOT, NAND, NOR, XOR, XNOR). It includes designs and simulations using Quartus II and ModelSim. The project covers ...

Gate Level Logic is the fundamental representation of digital circuits using basic logic gates such as AND, OR, NOT, NAND, NOR, XOR, and XNOR. It operates at the lowest level of abstraction in ...

Electrostatically controlled graphene P-N junctions are devices built on a single layer graphene sheet that can be turned-ON/OFF via external potential difference. Their electrical behavior resembles ...

FDSOI FET allows the threshold voltage ( V t ) to be adjustable (i.e., low-Vt and high-Vt states) by using the back gate bias. Our design utilizes the front and back gates of an FDSOI FET as the input ...

In this brief, a novel XOR/XNOR-function logic gate with two inputs, two enable inputs and one output is proposed and designed in Quantum-dot Cellular Automata (QCA) nanotechnology. In order to ...

In present work, improved designs for voltage controlled ring oscillators (VCO) using three transistors XNOR/XOR gates have been presented. Supply voltage has been varied from [1.8 - 1.2] V in ...

“However, we were able to successfully design an XNOR logic gate prototype with a novel structure, by layering bipolar and unipolar memristor types in a novel heterogeneous structure, which led to a ...
