This book was released on 2004-11-12 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on high performance radio frequency integrated circuits (RF IC) design in CMOS. 1. Development of radio frequency ICs Wireless communications has been advancing rapidly in the past two decades. Many high performance systems have been developed, such as cellular systems (AMPS, GSM, TDMA, CDMA, W-CDMA, etc. ), GPS system (global po- tioning system) and WLAN (wireless local area network) systems. The rapid growth of VLSI technology in both digital circuits and analog circuits provides benefits for wireless communication systems. Twenty years ago not many p- ple could imagine millions of transistors in a single chip or a complete radio for size of a penny. Now not only complete radios have been put in a single chip, but also more and more functions have been realized by a single chip and at a much lower price. A radio transmits and receives electro-magnetic signals through the air. The signals are usually transmitted on high frequency carriers. For example, a t- ical voice signal requires only 30 Kilohertz bandwidth. When it is transmitted by a FM radio station, it is often carried by a frequency in the range of tens of megahertz to hundreds of megahertz. Usually a radio is categorized by its carrier frequency, such as 900 MHz radio or 5 GHz radio. In general, the higher the carrier frequency, the better the directivity, but the more difficult the radio design.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been an extensive effort to develop low-cost implementations of radio frequency integrated circuits for consumer applications. This thesis is a research effort in the design and implementation of integrated RF CMOS Power Amplifiers (PAs). A significant challenge in the implementation of RF CMOS ICs is the impact of device, package and passive element parasitics on circuit performance. Passive components are a critical part of any RF IC design, and a process optimized for digital circuits results in inductors and capacitors with very high parasitics. In this work, we have developed a compact model for inductors fabricated in a digital CMOS process. Measured results have been used to further refine the accuracy of the inductor model. This model has been used to predict the impact of inductor parasitics on the performance of RFICs, and is also simple enough to be included in a CAD tool for circuit optimization. We have also studied the operation of Class A, B and C power amplifiers and highlighted design issues which are specific to the implementation of integrated PAs. It is shown that inductor loss has the most critical impact on the performance of integrated PAs. A custom CAD tool, based on the simulated annealing algorithm, has been developed to optimize the performance of power amplifiers for maximum efficiency in the presence of package, device and passive element parasitics. This CAD tool simulates the process of load-pull to determine the optimum large-signal load impedance for the PA, and optimizes the matching network design based on the trade-off between the loss in the matching network and its impedance transformation properties. This trade-off is relevant in the case of high-loss matching networks only, as is the case in integrated RF CMOS ICs. This CAD tool has been used to optimize the efficiency of balanced 100mW CMOS PAs operating at 900MHz. Measured results validate the design and optimization process outlined in this work. It is demonstrated that in the design of RF CMOS ICs, significant benefits can be gained by incorporating parasitics into the design process by means of CAD optimization. The CAD tool developed is an effort towards achieving this goal. It is further proposed that CAD optimization is an essential part of the design of RF CMOS ICs in general, and with the development of improved package, device and passive element models, CAD optimization will replace the "tuning" of RF circuits and result in robust, fully-integrated implementations of RF circuits.

Download or read book CMOS RF Power Amplifier Design Approaches for Wireless Communications written by Sataporn Pornpromlikit and published by . This book was released on 2010 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the design of CMOS power amplifiers for modern wireless handsets, where stringent linearity requirements and high power efficiency are difficult to achieve simultaneously. CMOS technology has been an attractive technology for research in fully-integrated transceivers due to its low cost and high-integration capability, as well as its continuously improving high-frequency performance. Its advantages, however, come at the cost of continuously reduced breakdown voltages, low isolation and high power loss in the substrate. To address these limitations, a stacked-FET design technique is first developed to systematically divide the voltage stress among several transistors connected in series, allowing the use of a larger supply voltage. The voltage swing of each stacked device is added in phase to provide a larger output power to the load without the requirement of a large impedance transformation. To investigate this technique, a fully-integrated 20 dBm RF power amplifier is first implemented using 0.25-[mu]m silicon-on-sapphire MOSFETs. By using triple-stacked FETs, the optimum load impedance for a 20 dBm power amplifier increases to 50 [Omega] so impedance transformation is not required at the output. Measurement of a single-stage linear power amplifier shows a small-signal gain of 17.1 dB and a saturated output power of 21.0 dBm with a power added efficiency (PAE) of 44.0% at 1.88 GHz. With an IS-95 code division multiple access (CDMA) modulated signal, the power amplifier shows average output power of 16.3 dBm and PAE of 18.7% with ACPR below -42 dBc. The concept is then further demonstrated at higher voltage and power level. A single-stage quadruple-stacked-FET linear power amplifier is presented using 0.28-[mu]m 2.5-V standard I/O FETs in a 0.13- & mu;m silicon-on-insulator (SOI) CMOS technology. The PA is designed to withstand up to 9 V of supply voltage before reaching its breakdown limit. The measured PA achieves a small-signal gain of 14.6 dB, a saturated output power of 32.4 dBm, and a PAE of 47% at 1.9 GHz with a 6.5-V supply. Using a reverse-link IS-95 CDMA modulated signal, the PA shows an average output power of up to 28.7 dBm with a PAE of 41.2% while meeting the adjacent channel power ratio requirement. The PA also shows an average output power of up to 29.4 dBm with a PAE of 41.4% while meeting the adjacent channel leakage ratio requirement of an uplink wideband code division multiple access (WCDMA) modulated signal. These performances are comparable to those of GaAs-based power amplifiers. To fully exploit the advantages of higher-speed CMOS technology and the availability of co-integrated digital circuitry, a digital-intensive transceiver architecture is explored as an alternative in the second part of the dissertation. A single-ended digitally-modulated power amplifier (DPA) is demonstrated in a 0.13-[mu]m 1.2-V SOI CMOS technology, to be used in a multi-standard RF polar transmitter. The amplitude modulation is done by digitally controlling the number of activated unit amplifiers whose currents are summed at the output. The DPA is designed for multi-mode multi-band functionality by avoiding frequency-selective components, except for the final-stage output matching network. The measured DPA delivers a 24.9-dBm peak output power at 900 MHz with a maximum power efficiency of 62.7%. Similar high-efficiency performance is also exhibited at 1.92 GHz with a reconfigured matching network. By employing a digital pre-distortion technique, the DPA could meet linearity requirements for both the enhanced data rate for GSM evolution (EDGE) and WCDMA standards.

This book was released on 2010-06-17 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanometer CMOS RFICs for Mobile TV Applications focuses on how to break the trade-off between power consumption and performance (linearity and noise figure) by optimizing the mobile TV front-end dynamic range in three hierarchical levels: the intrinsic MOSFET level, the circuit level, and the architectural level. It begins by discussing the fundamental concepts of MOSFET dynamic range, including nonlinearity and noise. It then moves to the circuit level introducing the challenges associated with designing wide-dynamic range, variable-gain, broadband low-noise amplifiers (LNAs). The book gives a detailed analysis of a new noise-canceling technique that helps CMOS LNAs achieve a sub - 2 dB wideband noise figure. Lastly, the book deals with the front-end dynamic range optimization process from the systems perspective by introducing the active and passive automatic gain control (AGC) mechanism.
