正确选择输入网络，优化高速ADC的动态性能和增益平坦度
摘要：该应用笔记论述了如何选择适当的变压器和无源元件，并在不牺牲高速ADC动态性能的情况下获得较宽的输入频响的增益平坦度。 对于较高IF的模/数转换器(ADC)，正确选择板级元器件是满足高动态性能和较宽增益平坦度的必要条件。本技术资料介绍了如何选择输入网络，借助宽带变压器、端接电阻和滤波电容，简化单端到差分信号转换的设计。 本文以MAX1449为例进行说明和分析，给出了两种可能的输入配置。图1表示

在高中频ADC应用中，如何改善增益平坦度同时又不影响动态性能
摘要：本文指导用户选择适当的变压器，用于高速模/数转换器(ADC)前端的信号调理。本文还阐述了如何合理选择无源元件，在较宽的输入频率范围内改善增益的平坦度，而且不会牺牲ADC的动态特性。文中给出了变压器原级和次级匹配的差别，详细描述了中等频率至高频应用中高速ADC设计所面临的增益平坦度与动态范围的冲突问题。 本文讨论一种将单端信号(通常来自经过缓冲的解调电路)转换成差分信号(以便馈入高中频ADC)
