Temes and Dr. Un-Ku Moon, for the guidance and support. They gave me a chance to start my education here, and provided a very good environment for my research and study. I would also like to acknowledge the other members of my committee, for taking the time to serve on my defense. I would like to thank Bill McIntyre for guiding me throughout the whole design, and thank all the other people in Grass Valley Group, National Semiconductor, for their helping. All my classmates and colleagues in the Analog Group are always not hesitated to offer their hands to me when I need their help. First, I would like to thank Arun Rao. He offered great help to me from the beginning of my research in school to my chip design in Grass Valley. I would also like to thank José Silva for helping with tools, Pavan, Jipeng, Xuesheng and Mingliang for helpful discussion.
