1. Title:     MOSFET's and IV Curves

2. Introduction
The goal of this lab was to learn how to design a layout for a NMOS IV and PMOS IV  in ElectricVLSI by following the instructions of the tutorial 2.


3. Materials and Methods
In this lab we used a software call ElectricVLSI and the tutorial given by DR Li. We created a new cell for the NMOS and PMOS node that we designed, we changed the length, labeled the nodes and simulates the currents in LT Spice, we dod this for both nodes in schematic and layout. We learned how to check for erros annd adressed them.


4. Results
In figure the schematic of the nodes of NMOS and PMOS are showen after were modified in terms of lenght and names of dimantions, then we are showing on Figure 2 the layout version of this two nodes.
Figure 3 We have the simmulations of the nodes in Figure 1 squematics and with the respective code to make them work.

Figure 2 Lay out of NMOS and PMOS with code.


Figure 3 Squematics in Spice of using that scode showed respectively.



Figure 4 Layouts ran in Spice with the code showned



5. Discussion.

In this lab we got designed a MOSFET's and thier respectively IV Curve, lernded how to labaled, sized, check for errors, run on Spice. Great second lab of this series of 6 in total. We found out that if we check the schematic and the layout for mistakes at a goog rate of progression during design, we can avoid headache in the future when it comes down to debuging the whole system.
