  • 了解模数转换器的噪声、ENOB

    Abstract: Specifications such as noise, effective number of bits (ENOB), effective resolution, and noise-free resolution inlarge part define how accurate an ADC really is. Consequently, understanding the performance metrics related to noise isone of the most difficult aspects of transitioning from ...

  • ADC中精确度与分辨率认识

        ADC制造商在数据手册中定义ADC性能的方式令人困惑,并且可能会在应用开发中导致错误的推断。最大的困惑也许就是“分辨率”和“精确度”了——即Resolution和Accuracy,这是两个不同的参数,却经常被混用,但事实上,分辨率并不能代表精确度,反之亦然。本文提出并解释了ADC&l ...

  • DAC技术用语 (D/A Converters Defini

    Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non-linearity is a measure of theworst case deviation from the ideal 1 LSB step. For example,a DAC with a 1.5 LSB output change for a 1 LSB digital codec ...
