As CMOS technology continues to advance to smaller feature sizes, digital-logic circuits use less power while becoming faster and smaller. On the other hand, wireless analog circuits often benefit from the higher speed, but suffer various ill effects making conventional analog circuits difficult to design. Integrating wireless analog functionality onto high-volume CMOS greatly reduces the size and cost of wireless devices, which is motivating a tsunami of engineering innovation. In this work we present three wireless analog functions in CMOS: a linearized varactor, phased-locked loop (PLL), and power-amplifier (PA}. To improve the tuning linearity at the cost of a lower capacitance tuning ratio, many circuits tune a large varactor over a small portion of its tuning range. We demonstrate here that a conventional varactor's performance can be improved by breaking it into smaller, independently tuned, parallel segments. This increased tuning dimensionality can enable a varactor to be realized with a high tuning linearity over most of its tuning range while reducing the capacitance's dependence on the instantaneous radio-frequency input signal. In many applications, PLLs need to have a large fine-tuning frequency range to accommodate environmental drift such as temperature. Typically, the fine-tuning sensitivity of the varactor in a PLL's voltage-controlled oscillator is proportional to its fine-tuning range, which makes the PLL more susceptible to picking up noise and spurs. A new dual-path PLL architecture is introduced that uses a softly switched varactor array in a digitally controlled integral path. This architecture decouples the PLL's tuning sensitivity from its tuning range, thus achieving a very low fine-tuning sensitivity. To realize high spectral efficiency, many wireless schemes modulate both the radio-frequency carrier's phase and envelope, necessitating the use of a linear PA. Hence battery powered wireless transceivers require a PA that is both linear and power efficient, which, over even a modest dynamic range, would be difficult to implement in CMOS. Various PA linearization methods are discussed leading to the chosen polar-feedback method. The designs, implementations and measurements for some key blocks required for a PA with polar feedback are presented and the challenges remaining to implement a working system are discussed.

Advanced concepts for wireless technologies present a vision of technology that is embedded in our surroundings and practically invisible. From established radio techniques like GSM, 802.11 or Bluetooth to more emerging technologies, such as Ultra Wide Band and smart dust motes, a common denominator for future progress is the underlying integrated circuit technology. Wireless Technologies responds to the explosive growth of standard cellular radios and radically different wireless applications by presenting new architectural and circuit solutions engineers can use to solve modern design problems. This reference addresses state-of-the art CMOS design in the context of emerging wireless applications, including 3G/4G cellular telephony, wireless sensor networks, and wireless medical application. Written by top international experts specializing in both the IC industry and academia, this carefully edited work uncovers new design opportunities in body area networks, medical implants, satellite communications, automobile radar detection, and wearable electronics. The book is divided into three sections: wireless system perspectives, chip architecture and implementation issues, and devices and technologies used to fabricate wireless integrated circuits. Contributors address key issues in the development of future silicon-based systems, such as scale of integration, ultra-low power dissipation, and the integration of heterogeneous circuit design style and processes onto one substrate. Wireless sensor network systems are now being applied in critical applications in commerce, healthcare, and security. This reference, which contains 25 practical and scientifically rigorous articles, provides the knowledge communications engineers need to design innovative methodologies at the circuit and system level.

RF CMOS Power Amplifiers: Theory Design and Implementation focuses on the design procedure and the testing issues of CMOS RF power amplifiers. This is the first monograph addressing RF CMOS power amplifier design for emerging wireless standards. The focus on power amplifiers for short is distance wireless personal and local area networks (PAN and LAN), however the design techniques are also applicable to emerging wide area networks (WAN) infrastructure using micro or pico cell networks. The book discusses CMOS power amplifier design principles and theory and describes the architectures and tardeoffs in designing linear and nonlinear power amplifiers. It then details design examples of RF CMOS power amplifiers for short distance wireless applications (e, g., Bluetooth, WLAN) including designs for multi-standard platforms. Design aspects of RF circuits in deep submicron CMOS are also discussed. RF CMOS Power Amplifiers: Theory Design and Implementation serves as a reference for RF IC design engineers and RD and R&D managers in industry, and for graduate students conducting research in wireless semiconductor IC design in general and with CMOS technology in particular.

Circuit Design for Wireless Communications: Improved Techniques for Image Rejection in Wideband Quadrature Receivers is the first book focusing on the subject of image rejection in wireless receiver design, which has never been so important as high level of integration is highly demanded in the current and next generation mobile terminals. In this book, the image rejection problems in various receiver architectures which are suitable for high level of integration, including image-reject, direct conversion and low IF architectures, are studied. The fundamental source of the limitation of the image rejection in these receivers is the imbalance between their in-phase (I) and quadrature (Q) channels, which becomes more problematic when the receivers are of wideband. Besides traditional methods, this book provides novel solutions to the problem, which falls into two broad types. The first type refers to new circuits that produce less I/Q imbalance. This includeshigh performance switched-capacitor Hilbert transformers and precise quadrature sampling circuits. The second type is to compensate the I/Q imbalance, which is possibly frequency-dependent, in digital domain by calibration or signal processing techniques. Design examples have been included. Circuit Design for Wireless Communications: Improved Techniques for Image Rejection in Wideband Quadrature Receivers serves as a very useful reference for wireless design engineers who want to improve the image rejection of their wireless receivers and researchers and students who are interested in this subject.
