带隙基准源的现状及其发展趋势

An Overview of the Research on Bandgap Reference Sources and Its Development Trends

在模拟电路和混合模拟电路中,带隙基准电路作为一个很重要的单元,随着集成电路的发展和SOC系统的复杂化,已经越来越受到国内外学者的重视。本文简单介绍了传统的带隙基准源的基本原理,及其最近几年发展情况;分析了传统带隙基准的不足;重点介绍了国内学者所集中研究的几种典型带隙基准源电路。

Along with the development of IC and the complicated of SOC , Bandgap reference , which is an important unit in Integrated Circuits including Analog IC and Digital-Analog Hybrid IC, has already been regarded by scholars all over the world more and more importantly. The basic principle of traditional CMOS bandgap reference source was described, and the recent development of the bandgap reference circuit was introduced. Then some reasons for improving the traditional one to satisfy those requirements of contemporary IC＇s development were also pointed out.Finally, several typical and improved bandgap reference circuits in our country in recent years were analyzed ,respectively.
