EE
421L Digital Integrated Circuit Design - Lab 3
Layout
of a
10-bit digital-to-analog converter (DAC)
Pre-lab
work
- Back-up all of your
previous work from the lab and the course.
- Finish Tutorial 1 seen here.
This lab
will focus on the layout of the 10-bit
DAC you designed and simulated in Lab 2
- Use the n-well to layout a 10k resistor as discussed in Tutorial 1
- Discuss, in your lab
report, how to select the width and length of the resistor by
referencing the process information from MOSIS
- Use this n-well
resistor in the layout of your DAC
- Discuss, in your lab
report, how the width and length of the resistor are measured
- Ensure that each
resistor in the DAC is laid out in parallel having the same x-position
but varying y-positions (the resistors are stacked)
- All input and output Pins should be on metal 1
- DRC and LVS, with the extracted layout, your
design (show the results in your lab report)
- Zip up your final design directory and place it in the lab3 directory,
with a link on your lab report, so the grader can examine
both the layout and schematic (and simulations)
Ensure
that your html lab report includes your
name and email address at the beginning of the report (the top of the
webpage).
When finished backup your work (webpages
and design
directory).
