Chapter 3 QCA
QCA is a novel emerging technology in which logic states are not stored as voltage levels, but rather the position of individual electrons. Conceptually, QCA represents binary information by utilizing a bistable charge configuration rather than a current switch. A QCA cell can be viewed as a set of four “dots” that are positioned at the corners of a square. A quantum dot is a site in a cell in ...
متن کاملMagnetic QCA systems
The field-coupled QCA architecture has emerged as a candidate for providing local interconnectivity for nanodevices, and offers the possibility to perform very dense, high speed, and low power computing in an altogether new paradigm. Magnetic interactions between nanomagnets are sufficiently strong to allow room-temperature operation. We are investigating the fabrication and testing of arrays o...
متن کاملQca-based Nano Circuits Design
In order to design large digital circuits using Quantum-Dot Cellular Automata(QCA) cells, CAD tools and automated design methodology for QCA circuits are essential. This paper presents a QCA circuits design methodology based on traditional CMOS circuits design flow. This QCA circuits design methodology utilizes the current CMOS circuits design tools such as HSPICE and Synopsys Design Compiler. ...

متن کاملQCA: A Package for Qualitative Comparative Analysis
We present QCA, a package for performing Qualitative Comparative Analysis (QCA). QCA is becoming increasingly popular with social scientists, but none of the existing software alternatives covers the full range of core procedures. This gap is now filled by QCA. After a mapping of the method’s diffusion, we introduce some of the package’s main capabilities, including the calibration of crisp and...
