Hi all,
I have this question about the small signal model for a CMOS or a series connected Mosfets.how does the small signal model look like. I think in the case of a CMOS there will be two gm values, but a friend of mine told me only one will be for both of them because they are set in series. Same question I have with an Ntype mosfet set in series with an Ntype mosfet, what will gm be? will I have to add the gm for NMos with the gm for the Pmos? I am just a bit confused about that, I can draw a small signal model for a mosfet amplifier easily when it is not in series with another Mos or BJT, but when in series I get confused. would any one please help on this.
