Input-referred noise is certainly a departure from the ideal, and its effect on the overall ADC transfer function is shown in Figure 1. As the analog input voltage is increased, the “ideal” ADC (shown in Figure 1a) maintains a constant output code until a transition region is reached, ...
这些累积的噪声(通常称为ADC的输入参考噪声input-referred noise)。测试的时候就把驱动放大器的输入短接,读取一些数据进行计算一下的参数。 Noise-Free Resolution:无噪声分辨率定义为ADC稳定输出位数这是对ADC性能的极其保守的测量,因为无噪声分辨率的计算公式中源自峰峰值代码噪声,这极大地取决于样本总数,也就是说样本...

What is the best noise parameter to use for system noise analysis when using Delta-Sigma ADCs? For ADC noise analysis, we recommend usinginput-referred noise. We’ve bolded this phrase because it’s not common practice to use input-referred noise to define ADC performance. In fact, a majori...
摘要: Input-referred Noise (Code-Transition Noise) Practical ADCs deviate from ideal ADCs in many ways. Inputreferred noise is certainly a departure from the ideal, and its effect on the overall ADC transfer function is shown in Figure 1. As the analog input voltage is...
对于数据转换器而言,传统上是以dBFS/Hz来做为杂讯频谱密度的表示单位,也就是相对于满幅的每Hz的dB量测值。此资讯提供了杂讯位准的一种输出参考测量(Output Referred Measurement),或以dBm/Hz或什至dB mV/Hz为单位,以提供一较具绝对性质的测量:即数据转换器杂讯的输入参考指标(Input Referred Indication)。
