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.

"Conducting research in one of the top-notch Canadian universities and escaping the hot Indian summer - these were some of my expectations as I set out on my journey to the opposite end of the world. As my internship nears its end, I can gladly say that I have gained way more than that. Right from the outset, our GSA, Nilesh Patel, was there to make us feel at home in the foreign land. Under the able guidance of Dr. Xiaolin Wu, coupled with a really enthusiastic lab group, I had a wonderful research experience at McMaster University, Hamilton. The Industrial Engagement Week enlightened us about various Canadian industries and research - we realized that Canada is an emerging technological hub. Apart from an academically enriching experience, there were various other activities we engaged in - some enchanting, some wild and crazy!!! Be it canoeing down a river or sky-diving off a plane, experiencing the majestic Niagara Falls or the mystic Canadian Rockies, going on crazy roller-coaster rides or getting lost on a hiking trail, the summer of 2010 was one of the best times of my life - a truly memorable experience"
