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).
