The transfer characteristics of an NMOS transistor is the relationship between the gate-source voltage, which serves as the "input" port of a common-source amplifier, and the "output" drain current. To simulate the transfer characteristic of our 45nm NMOS PTM model, we can use this SPICE file and this Python script.
