- Generate the characteristic curves of NMOS and PMOS transistors.
MOS Transfer Characteristics
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.
To identify the different operating regions, we can
