MOSFETs and IV Curves

Introduction:
In this lab we used ElectricVLSI to build a MOSFET and then we analysed the curves in LTSpice.

Materials and Methods:
In this Lab we used the computer program ElectricVLSI to create the schematics that were then simulated in LTSpice.

Results:

Task 1: Build the MOSFET in Electric


Figure 1: Shows the Layout of an NMOS in Electric


Figure 2: Shows the Schematic of the NMOS with no NCC errors


Figure 3: Shows the Layout of a PMOS in Electric


Figure 4: Shows the Schematic of a PMOS with no NCC errors

Task 2: Simulate the PMOS and NMOS in LTSpice

Figure 5: LTSpice simulation of the NMOS


Figure 6: LTSpice simulation of the PMOS

5. Discussion
The lab was able to be successfully completed because we were able to build both models and run the tests without any errors. We can also see that the LTSpice simulation was done successfully and was similar to what we can see in the lab handout. The only difference is that in Figure 6 the x axis is reversed so it looks different from the lab handout.
