Book Enabling Millimeter wave Circuit Techniques for High Data Rate Communication

Download or read book Enabling Millimeter wave Circuit Techniques for High Data Rate Communication written by Najme Ebrahimiseraji and published by . This book was released on 2017 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation has been mainly focused on reconfigurable mm-wave integrated circuits for next generation wireless communication systems (namely, 5G). One of the major approaches to making 5G a reality is the use of high-frequency signals in the millimeter-wave (mm-wave) frequency band to facilitate access to more bandwidth. This can deliver faster and more reliable data to more users. This dissertation contributes to making wideband, bidirectional, and scalable RFICs for high data rate point-to-point communications over large distances in mm-wave bands, particularly the E-band (71-76 GHz, 81-86 GHz). The E-band is a licensed band in the US, with 10 GHz of bandwidth allocated to low-cost, high-capacity, and point-to-point communication. For backhaul base-stations or air-to-ground communication, a scalable and large-element phased array is desired to acquire the appropriate isotropic radiated power and signal to noise ratio. Additionally, bidirectional operation supporting transmit (TX) and receive (RX) in a single aperture is desirable to minimize the area and save power. This dissertation has focused on new architectures for scalable, bidirectional, and wideband phased arrays using IBM\textquoteright s fastest SiGe technology, 90 nm. In this dissertation, the first E-band scalable phased-array transceiver is proposed based on coupled oscillator architecture. Coupled oscillator phased arrays have the advantage of low power and low complexity, resulting in an architecture that easily scales to the number of elements as multiple die can be aggregated to form a larger array through local oscillator (LO) power distribution and intermediate frequency (IF) power combining. However, silicon processes introduce undesirable parasitics and manufacturing tolerances to the transistor and passive devices. When multiple oscillators are present in a single die, the oscillators couple through the substrate. The substrate coupling introduces additional parasitic coupling paths between oscillators; this causes pulling and, consequently, amplitude and phase variation between the oscillators. In addition, the parasitics from the injection node to the substrate deviate the ILO performance from its ideal behavior. Conventional analysis of the amplitude and phase noise typically ignores the effect of the silicon substrate parasitic effects. This dissertation investigated the nonlinear dynamics of an injection-locked oscillator (ILO), where the effective circuit parameters of ILO performance were observed. More specifically, new amplitude and phase equations are derived that took into account the transistor\textquoteright s device parasitics and silicon substrate\textquoteright s parasitic coupling effects, including the transistor injection node parasitic capacitance ($C_{P}$), substrate parasitic conductive ($R_{sub}$) and dielectric ($C_{j}$) features. The derived models are compared with both the simulation and measurement results. The proposed 2x2 transceiver phased array block diagram described in this dissertation employs 4 injection-locked oscillators (ILOs) operating at a lower frequency range (in this case, 1/4 of the desired LO frequency), followed by a frequency quadrupler, to form a beam in transmit and receive modes. The bidirectional front-end is designed to operate at E-band within 3-dB bandwidth. Since the ILO-based phase shifting is technically challenging at millimeter-wave bands due to the parasitics of the injection circuitry and the oscillator phase noise trade-offs, the high-frequency limitations of the ILO phase shifter is considered and wide locking range and a less parasitic sensitive solution for current injection using folded-cascode architecture is proposed. The proposed ILO-based phase array architecture result in low phase noise and low channel to channel isolation supporting 6 Gb/s data rate at 256 QAM modulation. The conventional architectures of the E-band transceiver require a wide tuning range, around 10 GHz, for the LO signal and wide-bandwidth IF blocks. The wide-bandwidth requirement of LO and IF frequency for mm-waves increases the power consumption and complexity of the system. This dissertation proposes a novel architecture, named the \textquotedblleft Image-selection\textquotedblright{} E-band phased array. This new architecture makes the upper-band (81-86 GHz) and the lower-band (71-76 GHz) of the E-band spectrum images of each other in comparison to the LO signal, which is located at the center frequency (78.5 GHz). Therefore, an image rejection architecture is desired to select the wanted band while rejecting the other. The significant advantage of this architecture is that it only requires an LO with the quadrature phases within a tuning range lower than 1 GHz . This will relax the system design trade-offs to the circuit impairments. For bidirectional operation purpose and preventing use of quadrature generation circuitry at direct intermediate frequency (IF) or radio frequency (RF) signal paths, sliding-IF weaver architecture mixers are employed with the phase inverter in the divider path to select the upper or lower band. This architecture leads in to a flat conversion gain over the bandwidth and low amplitude and phase imbalance. The achieved QAM modulation data rate from this technique is the state of art,\lyxdeleted{najmebi}{Mon May 29 19:43:48 2017}{ } 9Gb/s (64 QAM) with less than 5\% EVM and 12 Gb/s (16 QAM) with less than 10\% EVM.

Book Integrated Microwave and Millimeter wave Phased array Designs in Silicon Technologies

Download or read book Integrated Microwave and Millimeter wave Phased array Designs in Silicon Technologies written by Kwang-Jin Koh and published by . This book was released on 2008 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research focuses on the design and analysis of on-chip phased-array receivers and transmitters in silicon technologies. Passive phase shifters have been widely used in conventional discrete implementations of phased-arrays which are based on transmit/receive modules in III-V technologies. However their large volume and high loss impose several challenging issues for on-chip integration. To leverage system optimizations of on-chip phased-arrays, active phase shifter architecture is primarily investigated in this dissertation. The active phase shifter utilizes a quadrature signal interpolation where the I/Q signals are added with appropriate amplitude and polarity to synthesize the required phase. The quadrature signal generator is a key element for accurate multi-bit phase states in the active phase shifter. To generate lossless wideband quadrature signals, a novel I/Q signal generator based on second-order L-C series resonance is developed. Active phase shifters with 4-bit and 5-bit control are then designed in 0.13-um and 0.18-um CMOS technologies and tested successfully for 6-26 GHz phased-arrays applications, featuring the smallest chip size ever reported at these frequencies with similar phase resolutions. After successful demonstration of the active phase shifters, an eight-element phased-array receiver is developed in 0.18-um SiGe BiCMOS technology for X- and Ku-band satellite communications. The phased-array receiver adopts corporate-feed architecture implemented with active signal combiners. The phased-array receiver is rigorously characterized including channel-to-channel mismatches and signal coupling errors from different channels. The on-chip phased-array designs are then extended to millimeter-wave frequencies. A four-element phased-array receiver and a sixteen-element phased-array transmitter are designed using the SiGe BiCMOS technology and tested successfully for Q-band applications. Wilkinson couplers are compactly integrated for linear coherent signal combining in the Q-band phased-array receiver. Also in the Q-band transmitter array, passive Tee-junction power dividers are integrated as a linear signal feed network. The power divider is based on a coaxial-type shielded transmission line utilizing three-dimensional metal stack, which leads to a compact corporate-feed network suitable for large on-chip arrays. The sixteen-element phased-array transmitter marks the highest integration of phased-array elements known to-date, proving a good scalability to a large array of the proposed phased-array architecture. Also, each phased-array design integrates all digital control units and presents the first demonstration of on-chip silicon phased-array at the corresponding design frequency, solving one of key barriers for low-cost and complex phased-arrays.

Book Low Power Wireless Communication Circuits and Systems

Download or read book Low Power Wireless Communication Circuits and Systems written by Kiat Seng Yeo and published by CRC Press. This book was released on 2018-05-03 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing demand for extremely high-data-rate communications has urged researchers to develop new communication systems. Currently, wireless transmission with more than one Giga-bits-per-second (Gbps) data rates is becoming essential due to increased connectivity between different portable and smart devices. To realize Gbps data rates, millimeter-wave (MMW) bands around 60 GHz is attractive due to the availability of large bandwidth of 9 GHz. Recent research work in the Gbps data rates around 60 GHz band has focused on short-range indoor applications, such as uncompressed video transfer, high-speed file transfer between electronic devices, and communication to and from kiosk. Many of these applications are limited to 10 m or less, because of the huge free space path loss and oxygen absorption for 60 GHz band MMW signal. This book introduces new knowledge and novel circuit techniques to design low-power MMW circuits and systems. It also focuses on unlocking the potential applications of the 60 GHz band for high-speed outdoor applications. The innovative design application significantly improves and enables high-data-rate low-cost communication links between two access points seamlessly. The 60 GHz transceiver system-on-chip provides an alternative solution to upgrade existing networks without introducing any building renovation or external network laying works.
