Mixed-Signal IC Design

Join us!

We are interested in strengthening our ties with industrial partners. If your company has considered the development of custom integrated circuits to establish itself as a leader in its field, find out how you can take advantage of of collaboration with the university to cost-effectively develop custom integrated circuits. Take advantage of the talent and infrastructure in-place at the university, and help us develop a pool of talented students with experience relevant to your organization.

Design Tools

We have been developing mixed-signal design tools to support our projects. These tools provide added functionality to the Mentor Graphics suite of design tools that is being used for the design, simulation, and layout of our mixed-signal IC chips. These specialized add-ons are extensions of the Mentor Design Kit for MOSIS. The tools support CMOS, BJT (Bipolar), and BiCMOS processes.

Some of our developed tools for SDL (schematic driven layout)

The following are a few mixed-signal (IC's with mixed analog and digital circuits on a single chip) and related integrated circuits designed using Mentor Graphics and fabricated using the MOSIS service. Fabrication was in 1.2 micron and 2 micron CMOS, BJT (Bipolar), and BiCMOS processes.

How long does it take to get a design fabricated? See here.
