Cmos Inverter Small Signal Model. 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. For the small voltage levels in the signal is concerned small signal models are used.

For analog circuit applications the mosfet is operated in saturation region of operation. Low side and high side switch. Av gmn gmp ron rop this can be rather large.
