Projeto de circuitos integrados analógicos com transistores de nanotubos de carbono

Abstract

This work aims to present the design of analog circuits with Carbon Nanotube Transistors (CNTFETs), more specifically the design of differential amplifier and a folded cascode amplifier with carbon nanotubes. Because carbon nanotubes are a recent issue this work will explain from the physical principles of this material until the design of analog integrated circuits. Due the recente utilization of carbon nanotube trasistor in analog design, the design methodologies are not developed, thus this work propose a design methodology for it. To test the proposed methodolgy, the design of a differential amplifier and a folded cascod amplifier are made, where some and comparisons ans analysis are made, and the advantages are specified.
