摘要：交错多个模拟-数字转换器（ADC）通常采用增加一个转换器，有效样本率的意图，尤其是如果有没有或只有很少可用的现成的ADC完成所需的样品，线性交流等应用的要求。然而，时间交错的数据转换器是不是一件容易的事，因为即使有完美的线性元件，增益/偏移不匹配和时序错误可能会导致在输出频谱中意外马刺。时间交错的模拟-数字转换器和路障（以及如何补偿他们）的理论方法，设计师通常会建立一个时间交错系统时遇到下面的文章提供了宝贵的见解。Maxim>DesignSupport>TechnicalDocuments>Tutorials>A/DandD/AConversion/SamplingCircuits>APP989Maxim>DesignSupport>TechnicalDocuments>Tutorials>Basestations/WirelessInfrastructure>APP989Maxim>DesignSupport>TechnicalDocuments>Tutorials>High-SpeedSignalProcessing>APP989Keywords:interleaving,time-interleaving,high-speed,analog-to-digitalconverter,high-speedADC,coarsequantizer,finequantizer,flashconverter,bandwidthlimitation,offseterror,gainerror,mismatches,nonlinearities,clockphasenoise,clockjitterMar01,2001TUTORIAL989MultiplyYourSamplingRatewithTime-InterleavedDataConvertersMar01,200……

摘要：快速和超高速数据转换器的动态性能评估的最有用的技术之一是一致的采样。这种技术提高了快速傅立叶变换（FFT）的光谱分辨率和消除某些条件得到满足时的抽样窗口的需要。然而，如果不能满足相干采样条件，采样窗口可以使用。本应用笔记比较窗口采样相干采样，并提供了一个解释如何评价高速模拟-数字转换器（ADC），使用这两种方法，同时详细介绍各的优点和缺点。Maxim>AppNotes>A/DandD/AConversion/SamplingCircuitsBasestations/WirelessInfrastructureHigh-SpeedSignalProcessingKeywords:coherentsampling,windowsampling,high-speed,dataconverters,analog-to-digital,analogue-to-Mar29,2002digital,AtoD,A/D,converters,ADCsAPPLICATIONNOTE1040CoherentSamplingvs.WindowSamplingAbstract:Oneofthemostusefultechniquesforevaluatingthedynamicperformanceoffastandultra-fastdataconvertersiscoherentsampling.ThistechniqueincreasesthespectralresolutionofaFastFourierTransform(FFT)andeliminatestheneedforwindowsamplingwhencertainconditionsaremet.However,iftheconditionsforcoherentsamplingcannotbemet,windowsamplingcanbeused.Thefollowingapplicationnotecomparescohere……
