通常采用诸如峰值误差、积分非线性度或微分非线性度等参数来表征模-数转换器的性能。然而,这些参数已不能用来表征采用反馈和过采样结构的转换器的性能。本文提出了表征A/D转换器的线性,非线性和统计特性的另一些参数,并提出了一种新方法(称为正弦最小误差法)来估计这些参数的数值。所提出的方法同样适用计算机模拟或对试验测量实际电路的方法来分析A/D转换器的性能。 Parameters such as peak error, integral nonlinearity, or differential non-linearity are commonly used to characterize ADC performance. However, these parameters can no longer be used to characterize the performance of converters using feedback and oversampling architectures. In this paper, some other parameters that characterize the linearity, nonlinearity and statistical properties of the A / D converter are proposed. A new method (called Sine Minimum Error Method) is proposed to estimate the values ​​of these parameters. The proposed method is also applicable to computer simulations or methods of testing actual circuits to analyze the performance of A / D converters.
