- Get the circuit netlist (nmos.netl file) and put it in the following link:

/student_lab/digital_ic/variant_val/...

- Input files necessary for simulation.

For input files take: - Input slope: 50 ps and Output capacitive load value, Cload: 5 fF

1. The input file for defining the input characteristics of NMOS transistor in DC mode by using HSpice circuit simulation tool is listed below:

*NNOS Transistor
