本论文的主要内容是了解带 隙基 准电　 压源的性能指标，分析带 隙基 准电　 压源基本原理及基本结构，比较不同形式结构的带 隙基 准电压源并做出严谨的分析论证。总结(The main content of this paper is to understand the performance index of bandgap voltage reference, analyze the basic principle and basic structure of bandgap voltage source, compare the bandgap reference voltage of different form structure and make rigorous analysis and demonstration. The current method of increasing the temperature characteristics of the bandgap reference voltage is summarized, and then the method of improving the temperature compensation principle of the PSRR and the bandgap reference voltage of the bandgap reference is clarified. Finally, the HSPICE simulation tool is used to simulate the designed circuit and make the deep analysis. And then based on the C adence layout design software platform, first make the basic device, step by step to expand the layout, but also consider a)
