急.
P-Mos
Vthp0=-0.444V
Kp=0.083mA/v^2
λ=0.041(V^-1)
γ=-0.322(V^1/2)
2Φf=0.6V
求在Rbias=8.2kΩ
I=0.5mA时
Routp(如图)
快啊.
  有人能做吗?

Rbias不能等于8.2kΩ.
I=0.5mA
Vgs,M1=Vgs,M2=Kp(Vgs-Vthp)^2=0.5mA
Vgs,M1=2.89V
Vthp,M2=Vthp0+γ(sqrt(Vgs,M1-Φf)-sqrt(2Φf))=0.797V
Vgs,M2=3.25V
Vbias=10-2.89-3.25=3.86V
Rbias=V/I=7.73kΩ
Routp和Mp1A, Mp2A, Rbias无关
Routp=ro,M2(1+(gm=gmb)ro,M1)
ro,M1=ro,M2=1/λdId=48.8k
gm=sqrt(4KdId)=4gmb=0.41mA/V
Routp=1.26MΩ
