Book excerpt: 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.

This book was released on 2016-10-27 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variety of commercial and defense applications are expected to have sub-terahertz (THz) and mm-wave integrated circuits in the near future. Silicon (Si) technologies partly meet the demands but are limited in their power handling capability. III-V technologies, in particular InP, offer higher output power but fall short of their Si counterparts if it comes to integration density and complexity. Thus, research on hetero-integration of Si with InP has gained increasing interest. This work focuses on MMIC signal sources as important building blocks that are based on FBH’s 0.8 μm InP-DHBT transferred-substrate (TS) process, offering an InP-DHBT as well as an InP-on-BiCMOS version. This process is unique and provides interesting possibilities to realize integrated circuits in the frequency range between 100 GHz and more than 300 GHz. First, fundamental sources at 96 GHz and 197 GHz are presented. They deliver +9 dBm and 0 dBm output power with 25% and 0.5% overall DC-to-RF efficiency, respectively. Furthermore, 162 GHz and 270 GHz push-push sources are demonstrated utilizing an InP-on-BiCMOS process, which achieve -4.5 dBm and -9.5 dBm output power. Subsequently, multiplier-based signal sources are demonstrated including a full G-band (140-220 GHz) frequency doubler, which delivers +8.2 dBm at 180 GHz and more than +5 dBm in the range 160-200 GHz. The doubler circuit exhibits a power efficiency of 16% in this frequency range. Also, the highest frequency is reached by a wideband 328 GHz quadrupler, with -7 dBm output power at 325 GHz and 0.5% DC-to-RF efficiency. The final part is devoted to hetero-integrated circuits and the necessary design considerations. Two 250 GHz and 330 GHz sources are demonstrated that deliver -1.6 dBm and -12 dBm output power, respectively. These are the first hetero-integrated signal sources in this frequency range reported so far.

This book was released on 2015 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The terahertz (THZ) spectrum (0.3 - 3 THz) offers new opportunities to a wide range of emerging applications which demand high-quality THz sources, detectors, amplifiers, and integrated circuits. On-chip integration of planar transmission line passive components degrades their performance due to the conduction loss. Therefore, a hybrid integrated technology in which all of the high-quality passive components are implemented using a suitable off-chip planar integrated technology and the active devices are placed on-chip, has become the most promising approach. In this thesis, a low-cost and low-loss silicon-on-glass (SOG) integrated circuit technology is proposed for THz/millimeter-wave (mmW) applications. Highly-resistive intrinsic silicon (Si) is selected as the main guiding region due to its high transparency at mmW/THz frequency ranges and the maturity of Si-devices fabrication. In the proposed technology, all of the passive components and waveguide connections are made of highly-resistive Si on a glass substrate. The proposed technique leads to a high-precision and low-cost fabrication process, wherein the alignment between the sub-structures is automatically achieved during the fabrication process. This is performed by photolithography and dry etching of the entire integrated passive circuit layout through the Si layer of the SOG wafer. The SOG dielectric ridge waveguide, as the basic component of the SOG integrated circuit, is theoretically and experimentally investigated. A test setup is designed to measure propagation characteristics of the proposed SOG waveguide. Measured dispersion diagrams of the SOG dielectric waveguides show average attenuation constants of 0.63 dB/cm, 0.28 dB/cm, and 0.53 dB/cm over the frequency ranges of 55 - 65 GHz, 90 - 110 GHz, and 140 - 170 GHz, respectively. Extending the SOG platform toward the THz range is achieved by new SOG waveguide structures wherein the glass substrates below the Si channels are etched to reduce the effect of greater glass material loss at higher frequencies (i.e., > 200 GHz). To fabricate these structures, the glass substrate is etched in hydrophilic acid before bonding to the Si. Four new SOG configurations, called the suspended SOG, corrugated SOG, rib SOG, and U-SOG waveguides are proposed with their respective fabrication techniques for the THz range of frequencies. In the suspended SOG waveguide, a periodic configuration of Si beams supports the Si guiding channel over the etched grove on the glass substrate. Measurements of two suspended SOG waveguides show low attenuation constants of 0.031 dB/[lambda]0 and 0.042 dB/[lambda]0 (on average) over the frequency ranges of 350 - 500 GHz and 400 - 500 GHz, respectively. It is theoretically demonstrated that the rib SOG and U-SOG waveguides are promising candidates for THz high-density and low-loss integrated circuits. Rib SOG waveguide and U-SOG waveguide test devices are designed over the frequency bands of 0.8 - 0.9 THz and 0.9 - 1.1 THz. The proposed SOG waveguide technology can easily be extended to several THz with no limitations. A new mmW low-loss dielectric phase shifter integrated in the corrugated SOG platform is designed, fabricated, and measured. Phase shifts of 111 ° and 129 ° at frequencies of 85 GHz and 100 GHz, with maximum insertion losses of 0.65 dB and 2.5 dB, are achieved during measurements of the proposed phase shifter. Millimeter-wave integrated SOG tapered antennas are developed and implemented. The idea of a suspended SOG tapered antenna is demonstrated to enhance the radiation efficiency and the gain of the SOG tapered antenna over 110 - 130 GHz. The suspended SOG tapered antenna, which can function under two orthogonal mode excitations, shows measured efficiencies of higher than 90 % for the two vertical polarizations.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Design techniques and procedures to improve performances of radio-frequency and millimeter-wave front-end integrated circuits were developed. Power amplifiers for high data-rate wireless communication applications were designed using CMOS technology employing a novel device resizing and concurrent power-combining technique to implement a multi-mode operation. Comprehensive analysis on the efficiency degradation effect of multi-input-single-output combining transformers with idle input terminals was performed. The proposed discrete resizing and power-combining technique effectively enhanced the efficiency of a linear CMOS power amplifier at back-off power levels. In addition, a novel power-combining transformer that is suitable to generate multi-watt-level output power was proposed and implemented. Employing the proposed power-combining transformer, a high-power linear CMOS power amplifier was designed. Furthermore, receiver building blocks such as a low-noise amplifier, a down-conversion mixer, and a passive balun were implemented using SiGe technology for W-band applications.
