Book excerpt: Ever growing demands for higher data rate and bandwidth are pushing extremely high data rate wireless applications to millimeter-wave band (30-300GHz), where sufficient bandwidth is available and high data rate wireless can be achieved without using complex modulation schemes. In addition to the communication applications, millimeter-wave band has enabled novel short range and long range radar sensors for automotive as well as high resolution imaging systems for medical and security. Small size, high gain antennas, unlicensed and worldwide availability of released bands for communication and a number of other applications are other advantages of the millimeter-wave band. The major obstacle for the wide deployment of commercial wireless and radar systems in this frequency range is the high cost and bulky nature of existing GaAs- and InP-based solutions. In recent years, with the rapid scaling and development of the silicon-based integrated circuit technologies such as CMOS and SiGe, low cost technologies have shown acceptable millimeter-wave performance, which can enable highly integrated millimeter-wave radio devices and reduce the cost significantly. Furthermore, at this range of frequencies, on-chip antenna becomes feasible and can be considered as an attractive solution that can further reduce the cost and complexity of the radio package. The propagation channel challenges for the realization of low cost and reliable silicon-based communication devices at millimeter-wave band are severe path loss as well as shadowing loss of human body. Silicon technology challenges are low-Q passive components, low breakdown voltage of active devices, and low efficiency of on-chip antennas. The main objective of this thesis is to investigate and to develop antenna and front-end for cost-effective silicon based millimeter-wave phased array radio architectures that can address above challenges for short range, high data rate wireless communication as well as radar applications.

Book excerpt: In this thesis, based on the indoor channel measurements and ray-tracing modeling for the indoor mm-wave wireless communications, the challenges of the design of the radio in this band is studied. Considering the recently developed standards such as IEEE 802.15.3c, ECMA and WiGig at 60 GHz, the link budget of the system design for different classes of operation is done and the requirement for the antenna and other RF sections are extracted. Based on radiation characteristics of mm-wave and the fundamental limits of low-cost Silicon technology, it is shown that phased-array is the ultimate solution for the radio and physical layer of the mobile millimeter wave multi-Gb/s wireless networks. Different phased-array configurations are studied and a low-cost single-receiver array architecture with RF phase-shifting is proposed. A systematic approach to the analysis of the overall noise-figure of the proposed architecture is presented and the component technical requirements are derived for the system level specifications. The proposed on-chip antennas and antenna-in-packages for various applications are designed and verified by the measurement results. The design of patch antennas on the low-cost RT/Duroid substrate and the slot antennas on the IPD technologies as well as the compact on-chip slot DRA antenna are explained in the antenna design section.

Download or read book Area and Power Reduction Techniques for Millimeter wave Phased array Transceiver Front ends written by Kun-Da Chu and published by . This book was released on 2021 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demands for higher data rates continue to drive research for consumer products to develop new techniques for low-cost and long battery-life wireless radios. This dissertation explores and implements several single-chip CMOS integrated circuits which aim to enable high data rates for the new spectrum opportunity in future mm-Wave 5G radios as well as to improve the spectrum efficiency for current sub-6GHz communication systems.In the mm-Wave design, a 50-58GHz 2x2 phased-array receiver (RX) for 5G communication and radar systems is described. The RX utilizes a Gm-assisted matching network (MN) to reduce the noise figure (NF) of a conventional passive mixer-first RX by placing an extra gain of ~5dB prior to the down-conversion mixers with minimal additional components. In addition to the Gm-assisted MN, this prototype phased-array RX integrates a proposed Gm-assisted MN, mixer-first RX with translational feedback, Cartesian phase shifters as a baseband beamformer, poly-phase filters, and LO generation in TSMC 28nm CMOS, occupying a total area of 0.53mm2. This RX achieves a NF of 7dB, gain of 26dB, input P1-dB of -20dBm with an 8-GHz 3-dB BW and a S11 lower than -10dB over 22-GHz BW. Second, a novel highly-digital 2x2 phased-array receiver implemented in TSMC 28-nm CMOS with several techniques, including a feedforward noise-suppressing front-end, reconfigurable 0-3 SMASH CT-delta-sigma ADC, and digital beamformer. This proposed receiver enables the development of digital multi-beam phased-array with improved front-end NF, reduced silicon area, and low power consumption for future wireless systems. Third, a dual-mode V-band power amplifier (PA) that utilizes a reconfigurable 2/4-way power combiner is introduced to enable two discrete modes of operation and enhance the efficiency at power back-off. The power combiner employs two techniques to further improve the PA efficiency at power back-off: 1) usage of transformers with non-uniform turns ratios to reduce the difference in impedance presented to the PA cores between the two modes and 2) utilize a proposed switching scheme to eliminate the leakage inductance associated with the disabled path in back-off power mode. The 2-stage PA achieves a peak gain of 21.4dB with a fractional BW (fBW) of 22.6% (51-64GHz). At 65GHz, the PA has a Psat of +17.9dBm with an OP1dB of +13.5dBm and a peak PAE of 26.5% in full-power mode. In back-off power mode, the measured Psat, OP1dB, and peak PAE are +13.8dBm, +9.6dBm, and 18.4%, respectively. The PAE is enhanced by 6% points at a 4.5-dB back-off. The PA is capable of amplifying a 6-Gb/s 16-QAM modulated signal with an EVMrms of -20.7dB at an average Pout/PAE of +13dBm/13.6%, respectively. This PA was implemented in 16-nm FinFET, occupies a core area of 0.107mm2, and operates under a 0.95-V supply. Lastly, to improve spectrum usage of the current sub-6GHz systems, a triple-path transmitter (TX) self-interference cancellation (SIC) transceiver for full-duplex (FD) systems which achieves greater than 73dB of SIC is reported. An integrated electrical balance duplexer (EBD) is employed and works in concert with two pre- and post-LNA RF feedforward cancelers implemented as analog finite impulse response (FIR) filters to form a combined three-path cancellation architecture that achieves a deep on-chip TX SIC over a very wide bandwidth (BW). The on-chip self-interference cancellation of 72.8/70.1/65.2dB was measured by comparing integrated channel power difference at the receiver (RX) baseband (BB) output while applying orthogonal frequency-division multiplexing (OFDM) multi-carrier 64-QAM Wi-Fi packages at the transmitter input with a 20/40/80-MHz bandwidth, respectively. The receiver noise figure (NF) degradation due to the TX SI leakage improves from 8dB to 1.6dB after turning on both RF cancelers. TX SI leakage reciprocal mixing with the RX LO phase noise (PN) was also significantly reduced by 11dB up to 1-MHz offset frequency measured at RX BB output. This work integrates the whole transceiver signal path from the analog baseband to RF. The FD prototype chip is fabricated in TSMC 40nm CMOS process with a die size of 4mm2 that consumes 106mW (excluding PA). An Altera Cyclone III FPGA with ADC/DAC daughter board is used to emulate the digital baseband (BB) and executes a nearest neighbor search (NNS) algorithm to close the filter adaptation loop. The RX operates from 1.6GHz to 1.9GHz with a total noise figure of 8.09dB and an IIP3 of -17dBm while operating at the highest gain of 42dB. The TX has an output P-1dB/Psat of 10.6dBm/12.5dBm measured at the antenna port, respectively. This chip also integrates an integer-N synthesizer with a measured locking range from 3.52GHz to 4.28GHz. The synthesizer consumes 10.4mW with a phase noise performance of -117dBc/Hz measured at 1-MHz frequency offset. These four prototypes demonstrate various techniques to reduce power and area for future wireless systems, including the applications in mm-Wave front-ends for new spectrum opportunities with increased data rates as well as improved spectral efficient full-duplex radios for existing sub-6GHz bands.
