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...
“原点”的概念,在ADC的设计中有很多的联系,让笔者联想一下的话,可以有单位原点(Origin, 即为S域下极坐标or复数坐标的原点,DC概念与1/S的积分运算)、单位圆(Unit Circle,在设计NTF的稳定性设计中有着重要的作用)以及Delta函数(Impluse response的概念,始终贯穿着Discrete Time or Continuous Time Delta-Sigma Mo...
