噪声系数通常用于衡量一个电路和或者系统内部噪声大小，它通常用于比较不同电路或者系统噪声性能的好坏。噪声系数的定义如下： An Lively inductor largely features CMOS transistors & its operation is solely the same as a passive inductor. Concerning the mirror, I've noticed some references to working with resistive loads in extensive tailed pairs for reduced noise (from memory in AoE chapter 3... https://robertq000smf3.tdlwiki.com/user
