高速、低功耗折叠内插模数转换器研究与设计的开题报告【摘要】折叠内插模数转换器（FIMC）是一种新型的模数转换器，其能够实现高速高精度的模数转换。本文主要针对高速低功耗FIMC进行研究和设计，在分析现有FIMC的基础上，提出一种改进的FIMC架构，通过优化折叠互补脉冲宽度调制（F-CPWM）技术，实现了更高的转换速度和更低的功耗。本文将首先介绍FIMC的基本概念和工作原理，然后对现有FIMC的不足之处进行分析，并提出改进方案。接着，针对所提出的改进方案，进行详细的电路设计和模拟分析。最后，利用TSMC90nmCMOS工艺实现了FIMC原型电路，并进行了实验验证。实验结果表明，所设计的FIMC能够以1.2GS/s的速度实现12位转换，并且功耗仅为512mW，证明了所提出的架构和优化算法对FIMC的性能提升具有显著的作用。【关键词】折叠内插模数转换器；F-CPWM；高速；低功耗；电路设计【Abstract】FoldedInterpolatingModulusConverter(FIMC)isanewtypeofmodulator,whichcanachievehigh-speedandhigh-precisionmodulatedconversion.Thispapermainlyfocusesontheresearchanddesignofhigh-speedandlow-powerFIMC.BasedontheanalysisoftheexistingFIMC,animprovedFIMCarchitectureisproposed,whichachieveshigherconversionspeedandlowerpowerconsumptionbyoptimizingtheFoldedComplementaryPulseWidthModulation(F-CPWM)technology.ThispaperwillfirstintroducethebasicconceptandworkingprincipleofFIMC.Then,theshortcomingsoftheexistingFIMCareanalyzed,andanimprovementschemeisproposed.Subsequently,detailedcircuitdesignandsimulationanalysisarecarriedoutfortheproposedimprovementscheme.Finally,theFIMCprototypecircuitisimplementedusingTSMC90nmCMOStechnology,andexperimentalverificationiscarriedout.TheexperimentalresultsshowthatthedesignedFIMCcanachieve12-bitconversionataspeedof1.2GS/s,andthepowerconsumptionisonly512mW.ThisprovesthattheproposedarchitectureandoptimizedalgorithmhaveasignificanteffectonimprovingtheperformanceofFIMC.【Keywords】FoldedInterpolatingModulusConverter;F-CPWM;High-speed;Low-power;CircuitDesign
