EE 431: Digital Integrated Circuits
Lecturer: Dr. Mohammed Morsy Farag


This course introduces basics and fundamentals of digital integrated circuits and particularly CMOS circuits. Course objectives include:

  • Present MOSFET device structure and operation
  • Introducing Fabrication and Layout of MOS Devices
  • Study CMOS Inverters: Static and Dynamic Characteristics
  • Design CMOS Combinational Circuits and Sequential Circuits
  • Design and analyze memory and array circuits
  • Use layout, modeling, and simulation CAD tools to design and analyze digital ICs.

Teaching Load (Spring 2016):

  • Lecture (3 hours), Section (2 hours), Lab (2 hours)
  • Office Hours: Saturday from 10:30AM to 12:00PM.
  • Teaching Assistant: Eng. Mohamed Megahed

Course work and assesment (out of 100) are as follows:

  • Lab work: 15 marks
    • 5 Labs: Use L-edit and Spice to layout, model, and simulate different digital ICs taught in the course:
