1. MOSFETs and IV Curves


2. The purpose of this lab was to build a MOSFET in Electric and to be able to run simulations of MOSFETs. The simulations should analyze the IV curves of the MOSFETS. These MOSFETs will be comprised of PMOS and NMOS shematic and layout components formed in Electric and simulated in LTSpice.

3. Materials and Methods

LTSpice computer Application
Paper and Pencil
Electric VLSI Application

5. Discussion

Electric allows engineers to simulate complex MOSFET designs and simulate using LTSpice. This is a great tool because it allow the users to see the layout of NMOS and PMOS componets. LTSpice allowed the IV curves to be seen in real time of the NMOS and PMOS schematics and layouts. It helps to solidify how the curcuit is operating both symbolically and on a physical peice of silicon.
