Book Description
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.

Book Description
This thesis describes a systematic design methodology for millimeter-wave, low noise amplifiers (LNAs). It focuses on the inductively--leaded SiGe HBT cascodc LNA topology. Three LNAs operating at 50 and 65 GHz are fabricated in 0.18mum SiGe BiCMOS technology to validate the proposed methodology. The measured LNA performance agrees well With simulations and is close to the theoretical limit in the given technology. Several of the LNA low-noise design techniques are applied to the design of a 65-GHz receiver integrating an LNA, a down-conversion mixer, a full-rate VCO, and an IF amplifier. The fabricated receiver has a gain of 24 dB and a noise figure of 12 dB. Using compact on-chip inductors, the IC occupies an area of 0.6 mm2, several times smaller than similar published receivers. To the best of the author's knowledge, it is the first millimeter-wave silicon receiver to integrate the VCO on-chip.

Book Description
This dissertation describes the design and implementation of a monolithic 38 GHz low-noise amplifier using 0.25 $mu$m ion-implanted GaAs MESFETs and coplanar waveguide transmission lines. It describes the development of low-noise GaAs FETs, measurement and modeling of active and passive components, circuit design, simulation, fabrication, and characterization of the completed amplifiers. Wireless systems are reshaping the nature of today's telecommunications industry. Millimeter-wave data communication systems provide the large bandwidth which is needed for high information capacity systems. The noise figure of the front ends currently available is a limiting factor in the performance of these systems, due to the lack of commercially available low-noise amplifiers to boost signal levels prior to down conversion. Most systems use a mixer as the first element in the receiver, which results in a noise figure of 7-8 dB. If low-noise amplifiers with a noise figure of less than 4 dB were commercially available, this would result in at least a 3 dB improvement in sensitivity. This would allow for longer links and/or reduced transmitter power, which improve the performance/cost ratio of the link. The use of ion implanted MESFETs as the active devices in MMIC circuits results in a dramatic reduction in material cost and improvement in circuit yields in comparison with those for devices based on epitaxial material. Various industrial foundries currently use high-cost epitaxial material with the goal of obtaining superior high frequency gain and noise performance compared to those for simpler ion-implanted devices. This work explores the benefits and capabilities of ion implanted MESFETs in millimeter-wave integrated circuits and compares their performance to that of p-HEMTs. Low cost ion implanted GaAs MESFETs are demonstrated with performance equivalent to those of high cost p-HEMTs fabricated on epitaxial material with $rm Fsb{t} > 60$ GHz, $rm Fsb{min} 12$ dB at 10 GHz. Coplanar circuits are gaining acceptance as a viable alternative to microstrip circuits for Ka-band applications. Coplanar technology eliminates processing steps associated with backside vias which limit yield in most MMIC processes. This results in high yield and low cost circuits. This work describes the models used to accurately simulate coplanar components at millimeter-wave frequencies. Three-stage coplanar amplifiers are fabricated that have greater than 12 dB of gain at 38 GHz.

Book Description
Millimeter-Wave Integrated Circuits delivers a detailed overview of MMIC design, specifically focusing on designs for the millimeter-wave (mm-wave) frequency range. The scope of the book is broad, spanning detailed discussions of high-frequency materials and technologies, high-frequency devices, and the design of high-frequency circuits. The design material is supplemented as appropriate by theoretical analyses. The broad scope of the book gives the reader a good theoretical and practical understanding of mm-wave circuit design. It is best-suited for both undergraduate students who are reading or studying high frequency circuit design and postgraduate students who are specializing in the mm-wave field.
