Introduction
The purpose of this lab was to learn how to build MOSFETs in Electric
VLSI, run simulations, and view and analyse their IV curves.
Materials and Methods
The transistors were built using Electric VLSI and simulated using
LTSpice.

Discussion
The schematics and layouts matched and were error free, and the
simulation values were as expected.
