CMOS Imager Design in Cadence

April 2022
EN.520.216 Introduction to VLSI

Objectives:

  • Use Cadence to design a CMOS imager chip
  • Write a final report in IEEE format
  • Skills Applied & Outcomes:

  • Cadence schematic, layout, and simulations
  • Layout Vs. Schematic (LVS), Design Rule Check (DLC)
  • Comments:

    I sketching and designing layouts on paper and in the software, debugging, and writing the report. We made a few mistakes at the beginning but managed to fix them by the end of the project.
