This book was released on 2019 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: A current steering DAC-based average power tracking circuit for on-chip power amplifiers (PA) 3) A CMOS-based driver stage for GaN-based switched-mode power amplifiers applicable to fully digital transmitters This thesis highlights the trends in wireless handsets, the motivates the need for fully-integrated CMOS power amplifier solutions and presents the three novel techniques for reconfigurable and digital CMOS-based PAs. Chapter 3, presents the transformer-based power combiner for out-phasing transmitters. The simulation results reveal that this technique is able to shrink the power combiner area, which is one of the largest parts of the transmitter, by about 50% and as a result, enhances the output power density by 3dB. The average power tracking technique (APT) integrated with an on-chip CMOS-based power amplifier is explained in Chapter 4. This system is able to achieve up to 32dBm saturated output power with a linear power gain of 20dB in a 45nm CMOS SOI process. The maximum efficiency improvement is about [delta][eta]=15% compared to the same PA without APT. Measurement results show that the proposed method is able to amplify an enhanced-EDGE modulated input signal with a data rate of 70.83kb/sec and generate more than 27dBm of average output power with EVM

This book was released on 2011-01-11 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reconfigurable RF Power Amplifiers on Silicon for Wireless Handsets is intended to designers and researchers who have to tackle the efficiency/linearity trade-off in modern RF transmitters so as to extend their battery lifetime. High data rate 3G/4G standards feature broad channel bandwidths, high dynamic range and critical envelope variations which generally forces the power amplifier (PA) to operate in a low efficiency “backed-off” regime. Classic efficiency enhancement techniques such as Envelope Elimination and Restoration reveal to be little compliant with handset-dedicated PA implementation due to their channel-bandwidth-limited behavior and their increased die area consumption and/or bill-of-material. The architectural advances that are proposed in this book circumvent these issues since they put the stress on low die-area /low power-consumption control circuitry. The advantages of silicon over III/V technologies are highlighted by several analogue signal processing techniques that can be implemented on-chip with a power amplifier. System-level and transistor-level simulations are combined to illustrate the principles of the proposed power adaptive solutions. Measurement on BICMOS demonstrators allows validating the functionality of dynamic linearity/efficiency management. In Reconfigurable RF Power Amplifiers on Silicon for Wireless Handsets, PA designers will find a review of technologies, architectures and theoretical formalisms (Volterra series...) that are traditionally related to PA design. Specific issues that one encounters in power amplifiers (such as thermal / memory effects, stability, VSWR sensitivity...) and the way of overcoming them are also extensively considered throughout this book.

Book excerpt: In recent years, tremendous growth of the wireless market can be defined through the following words: smartphone and high-data rate wireless communication. This situation gives new challenges to RF power amplifier design, which includes high-efficiency, multi-band operation, and robustness to antenna mismatch conditions. In addition to these issues, the industry and consumers demand a low-cost small-sized wireless device. A fully integrated single-chip CMOS transceiver is the best solution in terms of cost and level of integration with other functional blocks. Therefore, the effective approaches in a CMOS process for the abovementioned hurdles are highly desirable. In this dissertation, the new challenges are overcome by introducing adaptability to a CMOS power amplifier. Meaningful achievements are summarized as follows. First, a new CMOS switched capacitor structure for high power applications is proposed. Second, a dual-mode CMOS PA with an integrated tunable matching network is proposed to extend battery lifetime. Third, a switchless dual-band matching structure is proposed, and the effectiveness of dual-band matching is demonstrated with a fully-integrated CMOS PA. Lastly, a reconfigurable CMOS PA with an automatic antenna mismatch recovery system is presented, which can maintain its original designed performance even under various antenna mismatch conditions. Conclusively, the research in this dissertation provides various solutions for new challenges of advanced mobile terminals.

Book excerpt: Advances in electronics have pushed mankind to create devices, ranging from - credible gadgets to medical equipment to spacecraft instruments. More than that, modern society is getting used to—if not dependent on—the comfort, solutions, and astonishing amount of information brought by these devices. One ?eld that has continuously bene?tted from those advances is the radio frequency integrated c- cuit (RFIC) design, which in its turn has promoted countless bene?ts to the mankind as a payback. Wireless communications is one prominent example of what the - vances in electronics have enabled and their consequences to our daily life. How could anyone back in the eighties think of the possibilities opened by the wireless local area networks (WLANs) that can be found today in a host of places, such as public libraries, coffee shops, trains, to name just a few? How can a youngster, who lives this true WLAN experience nowadays, imagine a world without it? This book dealswith the design oflinearCMOS RF PowerAmpli?ers(PAs). The RF PA is a very important part of the RF transceiver, the device that enables wireless communications.

This book was released on 2006-02-08 with total page 132 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.

Book Synopsis CMOS RF Power Amplifier Design Approaches for Wireless Communications by : Sataporn Pornpromlikit
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.
