Lab Work

    - Generate 4 schematics and simulations

        1)
A schematic for simulating ID v. VDS of an NMOS device for VGS varying from 0 to 5 V in 1 V steps while VDS varies from 0 to 5 V in 1 mV steps. Use a 6u/600n width-to-length ratio.

Results from Varying VGS from [0,5] with 1V steps


        2) A schematic for simulating ID v. VGS of an NMOS device for VDS = 100 mV where VGS varies from 0 to 2 V in 1 mV steps. Again use a 6u/600n width-to-length ratio.

        3) A schematic for simulating ID v. VSD of a PMOS device for VSG varying from 0 to 5 V in 1 V steps while VSD varies from 0 to 5 V in 1 mV steps. Use a 12u/600n width-to-length ratio.

        4) A schematic for simulating ID v. VSG of a PMOS device for VSD = 100 mV where VSG varies from 0 to 2 V in 1 mV steps. Again, use a 12u/600n width-to-length ratio.
