1.
Calculate the high level noise margin, NMH, for a CMOS inverter with
kn/kp = 2.5. This will more nearly reflect our class circuits.
Briefly discuss a comparison of your NMH value with the NML that we
calculated in class for the special case: kn/kp = 1.
2.
Submit a first draft L-Edit plot of your CMOS logic circuit project.
Please plot a composite with all 5 layers on one page with
easy-to-read fill patterns
Indicate overlaps and use lambda = 6 microns.
Indicate distances and include a legend
of layer fill patterns.
For full credit, on a separate page, include the circuit schematic,
logic gate diagram, Boolean expression and the truth table.
Hint: this assignment will be graded on general features,
not layout efficiency.
Do not worry (yet) about optimizing the layout.
See Graphics Layout Editors Site website for printing hints.
