hspice 模型文件中迁移率u0 的求取

My professor (a TI senior guy) gave us his routine design processes. The very first step is to determine the characteristics of the device of interest. The u0(k'), lambda, and vth are related to specific device dimensions. You can choose a short and a long channel lengths as typical design
parameters. Run simulation, read operating point data, and calculate needed values. The accuracy is quite good. The error between my theoretical estimation and the simulation is less than 5%.

谢谢，我试试看！以后还请大哥多多赐教！

因为U0的单位，要明白单位啊
SPICE里的值应该*E-4

模型里面有的

在1um以下的沟道短沟道效应明显加大，我们以前用的公式都是沟道较长时的近似公式，短沟道时公式不再成立，要计算时需要加上其它参数及高次项，手算很复杂

不好意思问一下那.35的栅氧厚度大概多少呢？回复 3# tjumicrosoft

U0可以通过仿真得到。
