大家好:
那位兄弟有能仿ggnmos的TLP脉冲下的时序图,让我学习下。谢谢!
我自己写的程序不知为什么有点问题。下面是程序段和Vd-time曲线图:
Device NMOS {
Electrode {
{ Name="s" Voltage=0.0 }
{ Name="d" Voltage= 0 }
{ Name="g" Voltage= 0 }
{ Name="sub" Voltage=0.0}
}

{name="sub" Temperature=300 SurfaceResistance= 0.001}
}

}
NMOS nmos("s"=n0 "d"=n1 "g"=n2 "sub"=n3)
Set (n0 = 0)
Set (n2 = 0)
Set (n3 = 0)
Plot "nodes.plt" (time() n0 n1 n2 n3 )
}
