description:
The purpose of this lab was to design, layout, and simulate a CMOS inverter.
Pre-Lab Work:
I backed up my work from my previous labs in my dropbox account.
I went through and finished Tutorial 3.
Actual Lab Work:
12u/6u Inverter( W of PMOS/W of NMOS):

Simulations:
A
parametric analysis was performed to simplify and see the different
capacitive loads ranging from 100fF to 100pF with a total of 4
step size together.
