Switched Mode Converters for Power Management Circuits
The objective of this project is to design and implement digitally controlled high efficiency DC-DC switching converters suitable for VLSI power management applications. The main challenge in this work is to develop a robust power management scheme to dynamically vary the supply voltage as a function of varying clock frequency for the VLSI chip. The purpose of this scheme is to provide supply voltages to the VLSI chip that is just sufficient to meet data processing speed requirement while minimizing the DC and MOS gate leakage (in deep sub-micron devices) power dissipation, thereby maintain optimized power consumption for all processing requirements. In addition, this project will also require the design and implementation of energy and area efficient on-chip voltage and temperature monitoring circuits to provide important information on the operating conditions to the power management system.
The student will be focusing on the design, implementation and testing of the interface and control circuits between multi-output DC-DC switching power supplies and the VLSI chip. The student will be introduced to various VLSI CAD tools such as Cadence and HSpice. He/She will also acquire design and testing experience of PCBs.

"Mitacs Globalink Program gave me an opportunity to work with a wonderful group of students at the University of Victoria. It helped me broaden my perspective about the wide range of interesting projects a Computer Science student can take up. With the continued guidance and support of my supervisor, Dr. Margaret-Anne Storey, I learned a lot about research in Human Computer Interaction during this period of 10 weeks. Not only this, the workshops and industrial tours organized by Mitacs added a lot more flavor to the overall experience and helped us develop some unique skills. This program was not only academically enriching but also a lot of fun!"
