Conversor analógico-digital destinado à integração.

Abstract

This course conclusion work is related to the design of an analog-to-digital converter double ramp type, for the integration. For this, we used the design tool Virtuoso® from Cadence® Integrated Circuits Company. The work is divided into four chapters. Chapter 1is an introduction, in which examines the principles of an analogdigital converter, a brief explanation of the tool used and the manufacturing technology and the flow of analog integrated design, the objectives and the structure of the text. Chapter 2 shows the topology of the proposed converter, as well as the functional components and their respective circuits. Chapter 3 deals with the simulation of the drive key components and its result. In Chapter 4 are made the work conclusions.
