Book excerpt: With the development of wireless communications, high data rate is becoming essential since it not only augments the current wireless systems but also enables many emerging applications. In order to achieve multi-gigabit-per-second data rates, the fifth generation communication system (5G) is moving forward to the millimeter-wave band, such as 24-29 GHz and 37-42 GHz. Since the frequency is more than 10 times than the current communication protocols, the wavelength is 10 times smaller, which makes the transmission line effects more notable and increases the design complexity. Moreover, the path loss is much larger and therefore a higher output power or antenna EIRP (effective isotropic radiated power) is required to overcome this loss. Previous millimeter-wave 5G research focused on narrow band, such as 28 GHz and 39 GHz. But if a single system can be wideband and include all of these bands, the simultaneous data rate can be increased and the system cost can be reduced. The research projects in this dissertation, in consequence, focus on different wideband RF ICs, and include power amplifiers (PA), low noise amplifiers (LNA), wideband phased-array receivers with high single-sideband rejection, wideband IQ receivers and wideband front-end circuits including phase-shifters and variable gain amplifiers. All of these circuits were done in advanced CMOS SOI technologies. The thesis concludes with a list of future work to be done in this area.

This book was released on 2022-11-08 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past years, wireless communication systems have been rapidly advancing to meet the high data-rate requirements of various emerging applications. However, the existing transceivers have typically been demonstrated using CMOS-compatible technologies that deliver a relatively low equivalent isotropic radiated power in a small unit cell. Moreover, the particular device characteristics are limiting the linear region for operation. Therefore, the main focus of this dissertation is to present and discuss new design methods for transceivers to solve these issues. To reduce the complexity of the transceiver module for further phased-array scaling, a low-noise power amplifier design approach is designed using a 0.15-μm GaN-on-SiC high-electron mobility transistor technology (HEMT). Utilizing a traded off interstage matching topology between loss and bandwidth, the conversion loss induced by the matching network could be effectively reduced. A stacked-FET configuration was adopted to enhance the power handling of the RF switch. Further improvement on the isolation bandwidth was investigated using theoretical analysis on the intrinsic effect of the passive HEMTs. With the successful implementation of the RF front-end circuits, transceiver modules were integrated on Rogers RO3010 substrate. The planar dual exponentially tapered slot antenna phased-array system showed a compact size with simple biasing network compared to the conventional transceiver approach. The presented T/R module was characterized with an over-the-air test at a distance of 1 m, overcoming the free space path loss of 64 dB. It also shows a high flexibility for further integration with a larger number of array systems, which is very promising for future 5G communication systems.

Download or read book Millimeter Wave Sub Terahertz CMOS Transceivers for High Speed Wireless Communications written by Shinwon Kang and published by . This book was released on 2014 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millimeter-wave and sub-terahertz frequency bands are available for wideband applications such as high data-rate communication systems. As the respective wavelength is on the order of a millimeter, a compact on-chip antenna can be designed, thereby reducing the overall form factor and obviating expensive off-chip packaging. However, the channel propagation loss increases significantly with the frequency. Although CMOS technology is prevalent in digital processing and data communication, CMOS devices are lossy and inefficient at such high frequencies. Thus, it is challenging to implement an efficient and wideband transceiver at sub-terahertz frequencies using CMOS technology. The aim of this dissertation is to demonstrate sub-terahertz wireless links for high-speed chip-to-chip communication in CMOS. First, transceiver architectures and building blocks are discussed to address the challenges and limitations of the CMOS process. Two fully integrated CMOS transceivers, a 260 GHz OOK transceiver and a 240 GHz QPSK/BPSK transceiver, are then demonstrated using on-chip antennas. Frequency multiplication and mixer-first design are employed to operate beyond the cut-off frequency. In the QPSK modulation, a maximum data rate of 16 Gbps is realized with an energy efficiency of 30 pJ/bit. These demonstrations show that millimeter-wave/sub-terahertz wireless communication can be a promising solution for high-speed chip-to-chip communication. Improvements in the energy efficiency and silicon area of these wireless links can result in replacing or complementing existing wired links.

This book was released on 2019 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: To meet the ever-increasing demands of computational power, multi-core processor integration has risen to new heights. The wireless network-on-chip is an emerging technology which seeks to augment inter-core interconnects on multi-core processors with high throughput, low power wireless interconnects. While this technology offers improvements in power and latency for on-chip communication networks, additional innovation is required to realize these system level benefits. To meet the speed, efficiency, and latency demands of the wireless network-on-chip architecture, highly efficient, wideband mmWave transceivers and sub-blocks must be designed.This thesis presents the design and analysis of mmWave transceiver sub-blocks as well as integrated transmitter and receiver systems. Two high-performance signal source circuits suitable for the requirements of the multi-band wireless network-on-chip architecture are presented. The first simultaneously provides multiple harmonically related outputs for non-overlapping frequency bands of a multi-band wireless network architecture. The signal source circuit consists of a 28 GHz voltage-controlled oscillator circuit which leverages transformer feedback for high output swing and low phase noise under a low voltage power supply and an efficient harmonic generation architecture. The second signal source leverages a phase-switched dual-mode inductor which presents different inductance under different phase excitation. In addition, a V-band receiver is presented which leverages a current re-use active feed-forward and feedback architecture for wide bandwidth demodulation and minimal power overhead. Additionally, the inductorless bandwidth extension technique reduces silicon area overhead. A W-band receiver is also proposed which leverages a dual-noise-matched active gain-boosted common-gate LNA architecture which provides wide input matching with reduced power overhead. Finally, a W-band transmitter based on a wideband direct-modulated on-off-keying oscillator is presented. Resonant pulse-generation is used to increase the initial energy across the resonant tank, dramatically reducing start-up time. Furthermore, dual active- and passive- Gm-boosting and adaptive amplitude control for reduced start-up time and decreased steady-state power consumption further improve the bandwidth of the direct modulation oscillator.The circuits described above were fabricated in a 65 nm CMOS technology and demonstrate state-of-the-art performance with low power consumption and low area overhead. The innovations in this work facilitate the low-power mmWave transceivers required for the multi-band WiNoC architecture.

This book was released on 2013 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, opportunities for utilizing the broadband spectrum available at millimeter-wave (mm-wave) frequencies has motivated research on both short and long-range, highly-integrated complementary metal oxide semiconductor (CMOS) transceivers. Prototype mm-wave CMOS transceivers have been demonstrated for application in high-speed data transfer (57-64 GHz), wireless back-haul (71-76 GHz), automotive radar (77GHz) and medical imaging (90 GHz) systems. However, in spite of promising results, large scale deployment of mm-wave CMOS transceivers in portable and hand-held electronics is currently hindered by front-end power-consumptions on the order of several watts. Moreover, as a first order approximation, power consumption is directly proportional to system bandwidth. Therefore, as the bandwidth requirements of systems increase, the challenge with on-chip power consumption will become increasingly difficult to solve. In this dissertation, techniques for optimizing the power and area of ultra-wideband millimeter-wave transceivers are described. This work resulted in the fabrication of three mm-wave integrated circuits (IC), all of which were realized in a 6-metal layer 40-nm CMOS process. The first IC is a multi-stage transformer-feedback based 11-to-13 GHz direct-conversion receiver. The device achieves a 16% fractional-bandwidth, a peak power-gain of 27.6dB, and noise-figure of 5.3dB while consuming 28.8mW from a 0.9V supply. Second, a compact 24-54GHz 2-stage bandpass distributed amplifier utilizing mirror-symmetric Norton transformations to reduce inductor component values allowing efficient layout to occupy an active area of 0.15mm2. The device has a 77% fractional-bandwidth, an overall gain of 6.3dB, a minimum in-band IIP3 of 11dBm, while consuming 34mA from a 1V supply. The third, and the IC which includes the most integration among the three, is an ultra-broadband single-element heterodyne receiver intended for use in low-power phased-array systems. The receiver maintains 17GHz of bandwidth from the mm-wave front end, through a high-IF stage, and to the baseband output. The device occupies 1.2mm2 and exploits properties of gain-equalized transformers throughout the signal path to achieve an overall 17GHz bandwidth 20dB gain with a flat in-band response, 7.8dB DSB NF, and a P[subscript-1dB] of -24dBm, while consuming 104mW off a 1.1V supply.

This book was released on 2020 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inevitable migration to deeply-scaled technology nodes forces special considerations on high-power, low-noise, and high spectral purity integrated circuits. The dissertation addresses these considerations for a wide spectrum of RF, mm-waves, and optical-wireline circuits in advanced CMOS SOI technologies. The major contributions are in distributed power amplifiers (DPAs), optical drivers, RF and mm-wave voltage controlled oscillators (VCOs), mm-waves low-noise amplifiers (LNAs), and high linearity mixers. The work in power amplifiers culminated in the design and measurement of several novel ultra-wide-band DPAs/drivers with 100+GHz of bandwidth (BW) in GlobalFoundries 45nm RFSOI technology. Several design techniques are introduced to break the gain-bandwidth (GBW), and power-BW trade-offs in conventional distributed designs. The first PMOS-only DPA with 100+GHz BW is demonstrated exploiting the decreasing gap between NMOS and PMOS performance in deeply-scaled technology nodes. Transistors stacking is exploited for high power while introducing two new stack compensation techniques, the multi-drive intra-stack and inter-stack coupling. Improved stability coupling networks and magnetic field confining transmission lines are also devised to allow high gain stable operation. Over 4.5 THz GBW is recorded from a cascaded DPA and over 100 Gb/s is measured in both 64-QAM and PAM-4 modulations for a CMOS modulator driver. The mm-wave 5G LNAs contributions focus on K/Ka bands designs for next generation phased-array systems and exploits the body-bias of fully depleted SOI devices to control the linearity and gain of LNAs in 22nm FDSOI technology. The efforts in RF and mm-waves LC VCOs focus on implementations in deeply scaled 22nm FDSOI technology node. New circuit techniques are proposed to allow ultra-low-voltage operation (sub 0.1 V), low flicker noise variability across the tuning range without a dedicated tuning for the common-mode, ultra-low phase noise while using thin-oxide only devices, and over 70% of tuning range spanning the X and Ku-bands. The work in high linearity mixers exploits the enhancement of the figure of merit of CMOS switches in new technology nodes, to implement all-passive 16-path harmonic-reject mixers with watt-level IIP3 and over 35 dBc harmonic rejection ratio for all harmonics up to 3 GHz.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The challenges in the design of CMOS millimeter-wave (mm-wave) transceiver for Gbps wireless communication are discussed. To support the Gbps data rate, the link bandwidth of the receiver/transmitter must be wide enough, which puts a lot of pressure on the mm-wave front-end as well as on the baseband circuit. This paper discusses the effects of the limited link bandwidth on the transceiver system performance and overviews the bandwidth expansion techniques for mm-wave amplifiers and IF programmable gain amplifier. Furthermore, dual-mode power amplifier (PA) and self-healing technique are introduced to improve the PA's average efficiency and to deal with the process, voltage, and temperature variation issue, respectively. Several fully-integrated CMOS mm-wave transceivers are also presented to give a short overview on the state-of-the-art mm-wave transceivers.

This book was released on 2014 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vastly under-utilized spectrum in the sub-THz frequency range enables disruptive applications including 10Gb/s chip-to-chip wireless communications and imaging/spectroscopy. Owing to aggressive scaling in feature size and device f [subscript T] /f [subscript max], nanoscale CMOS technology potentially enables integration of sophisticated systems at this frequency range. This dissertation mainly focuses on the design of a 210GHz fundamental transceiver and also covers the design of a W-band fully integrated imaging system utilizing a novel concept of spatial-overlapping super pixels. Firstly, a 210GHz transceiver with OOK modulation in a 32nm SOI CMOS process (f [subscript T] /f [subscript max] = 250/320GHz) is presented. The transmitter (TX) employs a 2x2 spatial combining array consisting of a double-stacked cross-coupled voltage controlled oscillator (VCO) at 210GHz with an on-off-keying (OOK) modulator, a power amplifier (PA) driver, a novel balun-based differential power distribution network, four PAs and an on-chip 2x2 dipole antenna array. The non-coherent receiver (RX) utilizes a direct detection architecture consisting of an on-chip antenna, a low noise amplifier (LNA), and a power detector. The VCO generates measured -13.5dBm output power; and the PA shows a measured 15dB gain and 4.6dBm [rho][subscript sat]. The LNA exhibits a measured in-band gain of 18dB and minimum in-band noise figure (NF) of 11dB. The TX achieves an EIRP of 5.13dBm at 10dB back-off from saturated power. It achieves an estimated EIRP of 15.2dBm when the PAs are fully driven. This is the first demonstration of a fundamental frequency CMOS transceiver at the 200GHz frequency range. Secondly, a W-band direct-detection-based receiver array in an advanced 0.18[mu]m BiCMOS process is presented, which incorporates a new concept of spatial-overlapping super-pixels for millimeter-wave imaging applications. The use of spatial-overlapping super-pixels results in (1) improved SNR at the pixel level through a reduction of spillover losses, (2) partially correlated adjacent super-pixels, (3) a 2©72 window averaging function in the RF domain, (4) the ability to compensate for the systematic phase delay and amplitude variations due to the off-focal-point effect for antennas away from the focal point, and (5) the ability to compensate for mutual coupling effects among the array elements. The receiver chip achieves a measured peak coherent responsivity of 1,150MV/W, an incoherent responsivity of 1,000MV/W, a minimum noise-equivalent power (NEP) of 0.28fW/Hz [superscript 1/2] and a front-end 3-dB bandwidth from 87-108GHz, while consuming 225mW per receiver element. The measured noise-equivalent temperature difference (NETD) of the SiGe receiver chip is 0.45K with a 20ms integration time.
