Small signal analysis of BJT in saturation region
The small signal analysis of a BJT when the BJT is in amplification mode:
is easy.However what happens when the BJT is in saturation mode?
Can we replace the dependent current source with a resistor for the small signal analysis in saturation region with the value of the resistor being the inverse of the slope Ic vs Vce?(yellow line).
I have searched the Internet a lot and couldnt find what I am saying in the post.Is it wrong to assume that the CE of a BJT when the BJT is in saturation can be replaced by a resistor?
