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.

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. Two important aspects that are key to keep the advances in RF PA design at an accelerate pace are treated: ef?ciency enhancement and frequen- tunable capability. For this purpose, the design of two different integrated circuits realizedina0. 11μmtechnologyispresented,eachoneaddressingadifferentaspect. With respect to ef?ciency enhancement, the design of a dynamic supply RF power ampli?er is treated, making up the material of Chaps. 2 to 4.

Mobile and wireless communications applications have a clear impact on improving the humanity wellbeing. From cell phones to wireless internet to home and office devices, most of the applications are converted from wired into wireless communication. Smart and advanced wireless communication environments represent the future technology and evolutionary development step in homes, hospitals, industrial, vehicular and transportation systems. A very appealing research area in these environments has been the wireless ad hoc, sensor and mesh networks. These networks rely on ultra low powered processing nodes that sense surrounding environment temperature, pressure, humidity, motion or chemical hazards, etc. Moreover, the radio frequency (RF) transceiver nodes of such networks require the design of transmitter and receiver equipped with high performance building blocks including antennas, power and low noise amplifiers, mixers and voltage controlled oscillators. Nowadays, the researchers are facing several challenges to design such building blocks while complying with ultra low power consumption, small area and high performance constraints. CMOS technology represents an excellent candidate to facilitate the integration of the whole transceiver on a single chip. However, several challenges have to be tackled while designing and using nanoscale CMOS technologies and require innovative idea from researchers and circuits designers. While major researchers and applications have been focusing on RF wireless communication, optical wireless communication based system has started to draw some attention from researchers for a terrestrial system as well as for aerial and satellite terminals. This renewed interested in optical wireless communications is driven by several advantages such as no licensing requirements policy, no RF radiation hazards, and no need to dig up roads besides its large bandwidth and low power consumption. This second part of the book, Mobile and Wireless Communications: Key Technologies and Future Applications, covers the recent development in ad hoc and sensor networks, the implementation of state of the art of wireless transceivers building blocks and recent development on optical wireless communication systems. We hope that this book will be useful for students, researchers and practitioners in their research studies.
