It is generally believed that CMOS 1/f noise is originated from the channel carrier density fluctuation or mobility fluctuation. The carrier density fluctuation depends on the Si-SiO_2 interface trap density and its energy in the band gap.
通常认为CMOS器件的1/f噪声来自沟道中载流子密度或迁移率的不规则变化,前者取决于Si-SiO_2界面态密度及其在禁带能级中的位置,后者则由载流子与声子群的散射决定。
