General Information:
I received my education in the UK and have been a member of the Department since 1969. I helped to found both the Signals and Systems Group and the VLSI Research Group. I am currently the Director of the VLSI Research Group, and the University Representative for the Canadian Microelectronics Corporation (CMC). I was one of the founding members of Micronet, the Federal Network of Centres of Excellence in microelectronic devices, circuits, and systems and I am the University Coordinator for the Windsor node in this network.
Research Areas:

My interests are in the general area of VLSI circuits and Systems for high performance digital signal processors. I have a particular interest in DSP computations, particularly associated with the representation and manipulation of numbers to perform the arithmetic. My interests also include the implementation of Neural Networks (both artificial and cellular); low power and low noise circuits for mixed-signal applications; new DSP algorithms; machine vision systems; video and image processing; DSP systems for hearing instruments; and recently, Micro Electro Mechanical systems (MEMs).

Courses taught:
Electronic Circuits II (a highlight this year was the introduction of an analog chip design into the course. The students designed a chip based on a given circuit; the chips were sent for fabrication and returned in time for the students to test them. Most of the chips worked...a great success!)

Computers II (Microcontrollers) (I have written a simulator which allows students to experiment with the basic blocks that go into the architecture of typical microcontrollers. In this year's course, the students worked on a project design using web based communication and reporting.)

VLSI Design (This is a graduate course that covers the basic theory of VLSI design from silicon to silicon compilers. Several easy to use software packages that run on a PC are used as the tools in this course)

VLSI Project (This graduate course allows students to explore the many commercial tool stes in the VLSI Research Lab. A chip design, fabrication and test are important milestones in this course.)

Research Lab:
The VLSI Research Lab is located in Essex Hall. We have a large number of workstations running industrial level design tools. Through the CMC, we have access to the latest technologies, including 0.35µ and 0.25µ CMOS. We also have comprehensive test equipment with which we evaluate our fabricated chips.
