急～，请高手指点－mos　lever４９模型

小弟最近在分析一个运放，使用的是mos　lever４９模型很多参数不知道是哪个，请高手指点，比如沟道调制系数等等

ding xian急～～谢谢各位高手，或者能提供模型说明．小弟先感谢了

有专门的说明文档
pcml是与沟道调制效应有关的参数，但是不知道与lambda是什么关系。

我找了好几天了，没有相关的文档，我开始也觉得pclm是沟道调制系数，但从仿真结果上发现不对

berkery bsim3v3 可以看一下

各种不同的模型，参数用的名称代码还是一样的，可以参照一下别的可以下到文档说明的对照看。

同问

沟道调制系数一般变化的，电路设置的参数不同，沟道调制系数也不同，所以一般模型里是没有的吧，你可以大致仿一下，然后估算它的范围?
不知道这种说法是否正确?

嗯，我一般也是这么做，不过一般用不上。只能大致计算用。
lamda随w/l变化很大，随电压偏执的不同变化也很大。感觉没有多少意义。
