What This Document Is
This is the first project assignment for Introduction to Digital Integrated Circuits (ELENG 141) at the University of California, Berkeley, from Spring 2004. It’s a practical design challenge focused on applying fundamental concepts of CMOS logic to a specific circuit implementation. The project is divided into phases, each building upon the previous one, and requires students to analyze, design, and optimize a digital circuit based on provided technology parameters. It’s a core component of the course, designed to reinforce theoretical knowledge with hands-on application.
