Millimeter-Wave Low Noise Amplifiers available in PDF, EPUB and Kindle. This book is the first standalone book that combines research into low-noise amplifiers (LNAs) with research into millimeter-wave circuits. In compiling this book, the authors have set two research objectives. The first is to bring together the research context behind millimeter-wave circuit operation and the theory of low-noise amplification. The second is to present new research in this multi-disciplinary field by dividing the common LNA configurations and typical specifications into subsystems, which are then optimized separately to suggest improvements in the current state-of-the-art designs. To achieve the second research objective, the state-of-the-art LNA configurations are discussed and the weaknesses of state-of the art configurations are considered, thus identifying research gaps. Such research gaps, among others, point towards optimization – at a systems and microelectronics level. Optimization topics include the influence of short wavelength, layout and crosstalk on LNA performance. Advanced fabrication technologies used to decrease the parasitics of passive and active devices are also explored, together with packaging technologies such as silicon-on-chip and silicon-on-package, which are proposed as alternatives to traditional IC implementation. This research outcome builds through innovation. Innovative ideas for LNA construction are explored, and alternative design methodologies are deployed, including LNA/antenna co-design or utilization of the electronic design automation in the research flow. The book also offers the authors’ proposal for streamlined automated LNA design flow, which focuses on LNA as a collection of highly optimized subsystems.

High Efficiency and High Linearity Power Amplifiers for 5G Wireless Communications available in PDF, EPUB and Kindle. With the increasing demand for higher data rates and the crowding of the cellular bands below 3 GHz, researchers are looking to the millimeter-wave frequency spectrum to define the next generation of mobile broadband communications. One of the biggest challenges in implementing a millimeter-wave solution is the low efficiency of commercially available millimeter-wave power amplifiers. Furthermore, the monolithic millimeter-wave integrated circuit (MMIC) power amplifiers also need to have high power with reasonable gain, good linearity and maintain a compact chip size. In Chapter 1 and Chapter 2 of this dissertation, a compact high efficiency Ka-band power amplifier and a highly linear amplifier using second harmonic injection will be demonstrated. The requirements are even more stringent when the amplifiers are deployed in wireless systems that have high peak to average power ratio (PAPR). Among the most popular solutions to achieve high efficiency at power back-off is the Doherty architecture. Thus far, Doherty power amplifiers have been primarily implemented in the spectrum below 3 GHz for cellular base stations. Very few millimeter-wave Doherty PA’s have been reported to date. The conventional Doherty architecture has several inherent drawbacks that cause low efficiency, occupy large chip size and limit the performance bandwidth. Therefore, in our work, we propose four different Doherty amplifier topologies improve the DPA performance: 1) An ultra-compact Doherty amplifier using 3-dimensional broadside coupler 2) A wideband reconfigurable Doherty amplifier 3) A high power density stacked-FET Doherty power amplifier with asymmetrical gate bias 4) A high efficiency asymmetrical Doherty power amplifier using novel load modulation scheme based on load-pull data. All the proposed DPAs are fabricated in a 0.15-[mu]m enhancement mode (E-mode) Gallium Arsenide (GaAs) process. The proposed techniques and experimental results will be discussed in Chapter 3, 4, 5 and 6.The content of this dissertation is a compilation of 18 manuscripts, all of which I am the author or co-author. The titles, publishers and publication dates of the manuscripts are listed on page xii and xiii in this dissertation.

Download and read online ebook Millimeter-Wave Power Amplifiers write by Jaco du Preez. This book was released on 2017-10-05. Millimeter-Wave Power Amplifiers available in PDF, EPUB and Kindle. This book provides a detailed review of millimeter-wave power amplifiers, discussing design issues and performance limitations commonly encountered in light of the latest research. Power amplifiers, which are able to provide high levels of output power and linearity while being easily integrated with surrounding circuitry, are a crucial component in wireless microwave systems. The book is divided into three parts, the first of which introduces readers to mm-wave wireless systems and power amplifiers. In turn, the second focuses on design principles and EDA concepts, while the third discusses future trends in power amplifier research. The book provides essential information on mm-wave power amplifier theory, as well as the implementation options and technologies involved in their effective design, equipping researchers, circuit designers and practicing engineers to design, model, analyze, test and implement high-performance, spectrally clean and energy-efficient mm-wave systems.

CMOS 60-GHz and E-band Power Amplifiers and Transmitters available in PDF, EPUB and Kindle. This book focuses on the development of design techniques and methodologies for 60-GHz and E-band power amplifiers and transmitters at device, circuit and layout levels. The authors show the recent development of millimeter-wave design techniques, especially of power amplifiers and transmitters, and presents novel design concepts, such as “power transistor layout” and “4-way parallel-series power combiner”, that can enhance the output power and efficiency of power amplifiers in a compact silicon area. Five state-of-the-art 60-GHz and E-band designs with measured results are demonstrated to prove the effectiveness of the design concepts and hands-on methodologies presented. This book serves as a valuable reference for circuit designers to develop millimeter-wave building blocks for future 5G applications.
