1. Lab 7: MOSFETS and IV Curves
2. Introduction
The purpose of this lab was to continue to fimiliarize ourselves with the Electric VLSI program by creating a PMOS and NMOS transistors and simulating the IV curves of them.

3. Materials and Methods
To simulate a PMOS and NMOS transitor Electric VLSI software was used. The layout and schematic views were used for both the transitors. This required changing the default transistor to a 4-terminal PMOS and NMOS configurations. To build the schematic and layout views of the both the transitors, the tutorial given to us by our teacher was followed. After they were built, we simulated the IV curves using LTSpice. Pictures of each view including the IV curves can be seen below.

5. Discussion
The titurial that was followed was very helpful in familiarizing myself with the software. It also helped with showing me how the transistors would be built and what can cause problems in the simulations. All the IV curves that were simulated matched the expectations run in this lab. Overall the lab was very successful and will help with understanding the software in the future.
