噪声系数(NF)是RF系统设计师常用的一个参数,它用于表征RF放大器、混频器等器件的噪声,并且被广泛用作无线电接收机设计的一个工具。许多优秀的通信和接收机设计教材都对噪声系数进行了详细的说明(例如参考文献1),本文重点讨论该参数在数据转换器中的应用。...
ANALOG INPUT BANDWIDTH is a measure of the frequencyat which the reconstructed output fundamental drops3 dB below its low frequency value for a full s...
零漂移放大器可动态校正其失调电压并重整其噪声密度。自稳零型和斩波型是两种常用类型,可实现 nV 级失调电压和极低的失调电压时间/温度漂移。放大器的 1/f 噪声也视为直流误差,也可一并消除。零漂移放大器为设计师提供了很多好处:首先,温漂和 1/f 噪声在系统中始终起着干扰作用,很难以其它方式消除,其...
