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)
- Resistors
- Capacitors
- BJT's
- Spiral inductors
- How to design a Spiral
inductor
and a Mathcad file
on spiral inductor design
and measured data
AMI 1.5 micron process

process.
Projects
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.
