Hi All,
I read Razavi book and got stuck at the below figure
I do not know how Figure3.23(b) be simplified to Figure3.23(c).
Thing that bother me is that why 1/(gm+gmb) connected to ground (vss) while ro is connected to delta V.
For existing configuration, I think 1/(gm+gmb) // ro so, the other ends of both resistors 1/(gm+gmb) and ro
have to be connected to the same potential.
Thank you very much for your explanation.
Regards,
Tomph
