“…It was first developed in North America to compete with Digital-AMPS (Digital Advanced Mobile Phone System) and it became quite popular. It is a second generation mobile phone system and with 1.25 MHz band width it supports a variable number of users [3][4][5]. It provides voice service along with a data rate of 14.4 Kbps.…”

Firstly, I would like to take this opportunity to thank my project supervisor, Professor Do Manh Anh, for his caring supervision and constructive criticism. What I have learnt from him is far beyond the scope of academic research. His optimistic character, unyielding will and foresight form the key to success. It is an invaluable experience to have been with Professor Do in the past 2 years. I am also very grateful to those kind and talented professors in the division of circuits and systems, especially Professor Ma Jian-Guo and Professor Yeo Kiat-Seng, for their helpful guidance and discussions during the project. I also like to give special thanks to the technical staff in IC Design Lab I, II, III, and Centre for Integrated Circuits and Systems (CICS), for their help during the implementation of the project. Many thanks go to other staff and students, Yan Guoqiang,

“…The full integration of heterodyne receiver is very difficult. In order to avoid the needs of external IR and IF filters, direct conversion (zero-IF) and low-IF architectures have increasingly gained popularity in recent designs of wireless communications systems [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

Ultra low-power low-noise amplifier designs for 2.4 GHz ISM band applications

The wireless communication industry is currently experiencing tremendous growth. In responding to the demand for a low-cost but high performance wireless front-end, many intensive researches on CMOS radio-frequency (RF) front-end circuits have been carried out. The ultimate goal is to minimize the trade-off between high performance and low-cost, low power consumption design. Low noise amplifier (LNA) is typically the first stage of a receiver. Its performance greatly affects the overall receiver performance. In this thesis, four LNAs are proposed. They are designed for the IEEE 802.15.4 standard in the 2.4 GHz ISM band. The first three LNAs are optimized for low NF and low power. An application of this type of LNA is to be used as the amplification stage before the active mixer in the receiver chain. Active mixer provides active gain while consuming some dc power. Therefore the LNA's gain requirement can be relaxed. But its power consumption needs to be low to compensate for the power consumption from the active mixer. With a relaxed gain, the LNA should have good NF to avoid degrading the overall receiver NF. The fourth LNA is IV ACKNOWLEDGEMENT During the long journey towards this doctoral degree, it would never be possible to come up with this dissertation and all the work that went into it, without the generous assistance and support of many great people. First and foremost, I would like to thank my supervisor, Professor Boon Chirn Chye, for his support over the whole research process. His advices on technical matters are invaluable, and his guidance is very critical for the successful of my research. Professor Boon"s patience in answering questions and instruction of writing papers are greatly appreciated. I am greatly indebted and respectful to Professor Do Manh Anh and Professor Yeo Kiat Seng for their encourages and supports. I"d like to thank Mr. Lim Wei Meng and my seniors, Aaron Do, Luo Sha, Ali Meaamar and Krishna Vamshi for their help in all of my designs, fabrications and measurements. Finally, I'd like to express my heartfelt thanks to my father, Tran Quang Hien, my mother, Pham Thi Tan, my sister, Tran Thi Quynh Nhu and my friend, Lim Y Hao, who have always encourage and support me. Despite many up-and-downs in my life, they are always there for me. Without their encouragement and inspiration, I would not have been the person who I am today.
