Today's date: 27Sep2023

    

Pre-Lab:

 

First, I backed up all my lab and course work to Google drive.

Next, a NMOS was generated in Tutorial 2. Provided below will be the schematic of a NMOS, the symbol, simulation, layout, and the LVS.

In order to LVS properly, the schematic had to be altered as seen below.

The process was repeated for PMOS.
