对于MOS管的仿真结果中有以下电容:
element 0:m1 0:m2
model 0:mn 0:mp
region Saturati Saturati

cgs 44.2814f 82.5447f
cgd 9.8013f 19.0950f
请问这五个电容都表示什么意义呢?
恳请达人指点!

第三个问题:
*** Output Resistance Related Parameter ***
+pclm = 5.216683 pdiblc1 = 0.110359 pdiblc2 = 4.669031E-3
+pdiblcb = 0 drout = 0.56 pscbe1 = 4.309869E8
+pscbe2 = 9.513696E-7 pvag = 4.8 delta = 0.01
+alpha0 = 1.548E-5 alpha1 = 17.2 beta0 = 40.9
输出电阻的相关截取如上,怎样从中得出其手算表示呢?
Razavi用的是lambda
Sansen用的是工艺参数VE,不知道怎么去挖掘唉。
工艺库不要管
这个很难不管。依然纠结中
输出阻抗就是gds取倒数
