前段时间正好在看,关于电路分析中,比较重要的几个单调函数。免不了绕到微积分的概念当中去。而这两年,笔者正好也是集成电路设计公司做着关于Sigma-Delta ADC的项目设计工作。因此,就发散联想了一下关于Sigma-Delta Modulator中基本概念,跟微积分之间是否存在着一似微妙的关系呢? 图1. Sigma,Delta,字面寓意 如果要是...
注意每次循环都关注误差和迭代数次之后统一测误差有不同,前者可以通过选择合适的post-filter分配权重减小误差(more in P9)。 更多有关一阶modulator的将在CHAP.2中阐述。 1.3 Higher-Order Single-Stage Noise-Shaping Modulators 提高调制器阶数可以增加环路增益,从而更强地抑制带内量化噪声,提升分辨率。关于二阶调制...
the operation principle of DSM indicates that as the orderLof DSM increases, the suppression effect on low-frequency harmonics of voltage is better, and the modulator resolution is significantly improved. Specifically, the DSM resolution is increased byL+0.5 bits when its operating frequency is double...
