Research Review on A/D Converter Based on Discrete Chaotic System

近年来,利用混沌对初始条件的敏感依赖性进行模数转换,逐步形成了一个新的混沌应用的方向。总结了国内外模数(A/D)转换器研究的文献,综述该新型A/D转换器的基本原理、组成结构和优势,并分析优化混沌A/D转换器的方法。最后,通过对研究现状的归纳总结,对混沌A/D转换器在电容充放电、数学模型改进、转换精度等方面进行展望。

In recent years, using the sensitive of chaos to the initial conditions as analog to digital converter（ADC） is gradually formed a new orientation of the application of chaos. The chaotic ADC,the principle and architecture of them are summarized in this paper. Also,the methods of optimizing ADC are analyzed. Finally ,by summarizing the research status of chaotic ADCs, this paper attempt to project potential future trends of charging and discharging of capacitances, improvement of mathematic modules, converting resolution and other aspects as well.
