Cmos Inverter Small Signal Model. Final small signal model of the nmos transistor in the saturation region. To characterize the transistor for that purpose it is used a model that considers that small signals are injected in the terminals of the transistor.
Low frequency small signal equivalent circuit figure 2 a shows its low frequency equivalent circuit. To characterize the transistor for that purpose it is used a model that considers that small signals are injected in the terminals of the transistor. That is all the stray capacitances are ignored.
Differences in pmos and nmos.
That is all the stray capacitances are ignored. The top fet mp is a pmos type device while the bottom fet mn is an nmos type.
