Compact Modelling in RF CMOS Technology

ii Declaration I hereby certify that this material, which I now submit for assessment on the programme of study leading to the award of Doctor of Philosophy is entirely my own work, that I have exercised reasonable care to ensure that the work is original, and does not to the best of my knowledge breach any law of copyright, and has not been taken from the work of others save and to the extent that such work has been cited and acknowledged within the text of my work. thank you for you keen interest that you took in my work, for the generous amounts of time that you allocated to me, for your attention to detail and for your exhaustive efforts to get the best out of me. Charles, it is my great honor to be one of your students. Your wise and rational way of thinking the world will surely bring me great benefit in my future life. Prof. Sun, thank you for seeing the potential and taking a chance on me. Without the opportunity you offered I wouldn't be where I am today! I am also very grateful to the School of Electronic Information and Engineering of HDU who supported this work. I would also like to thank the faculty, staff and colleagues at the School of Electronic Engineering for being supportive of my efforts here. I would like to thank everyone who believed in me and supported me throughout my entire studies. A special thanks goes out to Dr. Xiaojun Wang for all his help to facilitate my study in DCU. To Mr. Huang Wang, the improvement in the writing of my thesis is greatly due to your selfless help. To Mr. Jincai Wen, your experiences in RF CMOS passive devices have well promoted my research on the on-chip spiral inductor models. To the members of the RF Device Modeling Group in HDU, there are your efforts in each step of my achievements. In the near feature, I will have more time to lead you to climb the mountains, as well as to explore the broader academic and technical fields. Lastly, I am especially indebted to my family. They have always supported me in everything I have chosen to do and have been a source of strength when times were tough. This is as much for you as it is for me. I am who I am …
