“…The comparison with other mixers recently reported in [2,8,10] shows that the performance of the proposed mixer is much better in terms of IIP2 ( Table 2). The other aspects are comparable but achieved with much larger RF operation bandwidth.…”

“…The load impedance calibration technique [8] calibrates the unmatched resistance and capacitance to improve the IIP2, but it introduces DC offset at the output port meantime. The second-order inter-modulation products filtering technique [9] enhance the IIP2 by a filtering network, which is not suitable for a wide band down-converter.…”

This paper presents a semi-active in-phase/ quadrature inductor-less down-conversion mixer. The mixer consists of an active trans-conductance stage, a passive current switching stage, and a trans-impedance stage. A complementary input architecture has been used to increase the trans-conductance for a given bias current. An on-chip prescaler is added to provide the balanced LO signals, while the CMFB circuit in trans-conductance stage is designed to enhance linearity. The chip was achieved in a 0.13 lm CMOS technology. It features 5 dB conversion gain over a broad range from 800 MHz to 2.1 GHz, which supports Chinese TD-SCDMA/RFID standards simultaneously. The maximum IIP2 is ?76 dBm at 2.1 GHz and suitable for application within a direct-conversion receiver.Keywords Semi-active mixer Á Quadrature Á CMOS radio frequency integrated circuit Á Direct-conversion receiver Á Input second-order intercept point Á TD-SCDMA Á RFID

“…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.
