Book Description
The enormous potentials of millimeter wave (mm-wave) and terahertz (THz) frequency spectrum have sparked significant interest in breaking into this new frontier of technology. High-speed communication, imaging, spectroscopy and radar are just a few examples among many possible applications. Today, however, mm-wave and THz systems are mostly discrete, bulky and expensive, which significantly limits their accessibility and applications. Realization of integrated mm-wave/THz systems in low-cost and reliable silicon technologies can be a technological milestone, paving the way for tremendous opportunities both in high-tech market and academic research. This work is focused on tackling the major challenges of implementing mm-wave/THz integrated sources, including magnitude, bandwidth, radiation and beam steering of the source power. As we move to higher frequencies, the power that can be generated on chip continuously drops. Here, we have demonstrated a versatile method to maximize this power based on independent optimization of harmonic impedances. Scalable standing wave array structures are implemented based on efficient low-loss coupling schemes in order to further boost the produced power by increasing the number of contributing individual sources. Furthermore, we have presented a practical approach to maximizing radiation gain and consequently Equivalent Isotropic Radiated Power (EIRP) of the source by optimizing influential parameters of the radiation apparatus. Achieving wideband operation also becomes more challenging with increasing frequency. This is an important obstacle in our ability to take advantage of the uncongested and large available bandwidth at mm-wave/THz. We implemented standing wave oscillators and employed a varactor-less frequency tuning method to realize wideband operation. We considerably improved the bandwidth benchmark among state-of-the-art integrated radiator arrays in silicon technology. Furthermore, electronic beam steering is a crucial component of the modern wireless systems. However, realizing the necessary wide range of variable phase shift between sources is a difficult task at mm-wave/THz spectrum. Here, we have demonstrated a new phase shifting method based on combining standing and traveling waves and were able to achieve a record beam steering range among relevant published works to date. In this dissertation, we present the ideas, analysis, design methods and experimental results of four implemented prototype integrated circuits. First, a 230-GHz Voltage Controlled Oscillator (VCO) in a 65-nm CMOS technology is presented based on a coupled standing wave structure. This circuit is capable of providing high output power (3.4 dBm maximum) and wideband operation (8.3% frequency tuning range) simultaneously. Taking output power, bandwidth, power consumption and phase noise into account altogether, the circuit has a record performance figure-of-merit (FOM) compared to the state of the art. Then, a 0.34-THz 4-element scalable standing wave radiator array with 20.3 GHz (record bandwidth at the time of publication) and -10.5 dBm maximum radiated power is demonstrated, followed by a 0.34-THz wideband (15.1% frequency tuning range) and wide-angle (128° /53° range) 2D beam steering phased array, both in in 0.13μm SiGe BiCMOS. The phased array circuit has the largest bandwidth and widest steering range among integrated arrays above 300 GHz in silicon technology. Finally, a 0.46-THz 25-element scalable radiator array in a 65-nm CMOS is presented with high radiation gain through an optimized silicon lens set up. This coherent source delivers record EIRP of +19.3 dBm and 8.9% wide frequency tuning range, both largest values reported for integrated arrays above 400 GHz in silicon.

Book Description
The interest towards millimeter waves has rapidly grown up during the last few years, leading to the development of a large number of potential applications in the millimeter wave band, such as WPANs and high data rate wireless communications at 60GHz, short and long range radar at 77-79GHz, and imaging systems at 94GHz.Furthermore, the high frequency performances of silicon active devices (bipolar and CMOS) have dramatically increased featuring both fT and fmax close or even higher than 200GHz. As a consequence, modern silicon technologies can now address the demand of low-cost and high-volume production of systems and circuits operating within the millimeter wave range. Nevertheless, millimeter wave design still requires special techniques and methodologies to overcome a large number of constraints which appear along with the augmentation of the operative frequency.The aim of this thesis is to define a design methodology for integrated circuits operating at millimeter wave and to provide an experimental validation of the methodology, as exhaustive as possible, focusing on the design of low noise amplifiers (LNAs) as a case of study.Several examples of LNAs, operating at 60, 80, and 94 GHz, have been realized. All the tested circuits exhibit performances in the state of art. In particular, a good agreement between measured data and post-layout simulations has been repeatedly observed, demonstrating the exactitude of the proposed design methodology and its reliability over the entire millimeter wave spectrum. A particular attention has been addressed to the implementation of inductors as lumped devices and - in order to evaluate the benefits of the lumped design - two versions of a single-stage 80GHz LNA have been realized using, respectively, distributed transmission lines and lumped inductors. The direct comparison of these circuits has proved that the two design approaches have the same potentialities. As a matter of fact, design based on lumped inductors instead of distributed elements is to be preferred, since it has the valuable advantage of a significant reduction of the circuit dimensions.Finally, the design of an 80GHz front-end and the co-integration of a LNA with an integrated antenna are also considered, opening the way to the implementation a fully integrated receiver.

Book Description
This book comprehensively reviews the state of the art in millimeter-wave antennas, traces important recent developments and provides information on a wide range of antenna configurations and applications. While fundamental theoretical aspects are discussed whenever necessary, the book primarily focuses on design principles and concepts, manufacture, measurement techniques, and practical results. Each of the various antenna types scalable to millimeter-wave dimensions is considered individually, with coverage of leaky-wave and surface-wave antennas, printed antennas, integrated antennas, and reflector and lens systems. The final two chapters address the subject from a systems perspective, providing an overview of supporting circuitry and examining in detail diverse millimeter-wave applications, including high-speed wireless communications, radio astronomy, and radar. The vast amount of information now available on millimeter-wave systems can be daunting for researchers and designers entering the field. This book offers readers essential guidance, helping them to gain a thorough understanding based on the most recent research findings and serving as a sound basis for informed decision-making.

Book Description
The ultimate handbook on microwave circuit design with CAD. Full of tips and insights from seasoned industry veterans, Microwave Circuit Design offers practical, proven advice on improving the design quality of microwave passive and active circuits-while cutting costs and time. Covering all levels of microwave circuit design from the elementary to the very advanced, the book systematically presents computer-aided methods for linear and nonlinear designs used in the design and manufacture of microwave amplifiers, oscillators, and mixers. Using the newest CAD tools, the book shows how to design transistor and diode circuits, and also details CAD's usefulness in microwave integrated circuit (MIC) and monolithic microwave integrated circuit (MMIC) technology. Applications of nonlinear SPICE programs, now available for microwave CAD, are described. State-of-the-art coverage includes microwave transistors (HEMTs, MODFETs, MESFETs, HBTs, and more), high-power amplifier design, oscillator design including feedback topologies, phase noise and examples, and more. The techniques presented are illustrated with several MMIC designs, including a wideband amplifier, a low-noise amplifier, and an MMIC mixer. This unique, one-stop handbook also features a major case study of an actual anticollision radar transceiver, which is compared in detail against CAD predictions; examples of actual circuit designs with photographs of completed circuits; and tables of design formulae.
