Book Synopsis Efficiency Improvement Techniques for Millimeter-Wave Transmitters by : Narek Rostomyan
Download or read book Efficiency Improvement Techniques for Millimeter-Wave Transmitters written by Narek Rostomyan and published by . This book was released on 2018 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strong demand for mm-wave high data-rate links in emerging 5G communication systems has resulted in substantial interest in mm-wave silicon (Si) based radio front-ends. The efficiency of the PA is a significant factor in the overall power dissipation and thermal management of mm-wave transceivers which have arrays with a large number of antennas (RF channels). This dissertation focused mainly on circuit design techniques for cm/mm-wave CMOS power amplifier efficiency improvement at frequencies from 15 GHz to 28 GHz. In addition, a DSP based solution is proposed to increase efficiency and performance of cellular (LTE band) transmitters in the 1-3 GHz frequency range. For digital communication signals with multi-carrier modulation and high peak-to-average power ratios (PAPRs), high back-off efficiency of the PA is of significant importance. In the first part of the dissertation, possible implementations of linear and efficiency-enhanced CMOS PAs are described. The concept of stacking multiple FETs is applied in the design of symmetric and asymmetric Doherty power amplifiers, as well as compact linear PAs. The dissertation demonstrates that high power density can be achieved with PAs based on 4-stack power devices, while 2-stack devices can be designed to have exceptionally high efficiency due to lower losses. A two stage, high power Doherty PA that uses 4-stack devices in the final stages is demonstrated with more than 25 dBm output power and 25% back-off power added efficiency (PAE) at 6 dB back-off operating in the 15 GHz band. To minimize chip area, the Doherty combiner is based on an optimized, lumped element 90 degrees phase shifter. To overcome the inherent non-linear gain response of Doherty PAs and to minimize the complexity of digital pre-distortion (DPD) due to large channel bandwidth at mm-wave bands, a simple RF domain analog pre-distorter is demonstrated for the first time. Various compact, linear 2-stack PAs are demonstrated based nMOS and pMOS FETs for saturated output powers in the range of 20 dBm in the Ka-band. Performance and reliability advantages of pMOS based PAs are shown. Also, by using inter-node impedance tuning with a shunt feedback drain-source capacitor, the PAE of the 2-stack PAs is increased even further, resulting in world record 46% PAE for the pMOS PA at 26.5 GHz. Due to high passive losses in CMOS, achieving high efficiency Doherty PAs requires careful design and non-conventional synthesis methodology for the Doherty combiner. A high efficiency, symmetric Doherty PA for the Ka-band that is based on efficient 2-stack power devices and a low loss Doherty combiner synthesis technique is presented. At 6 dB back-off, the PAE exceeds 28% which corresponds to 1.4x higher PAE than achievable with ideal class B back-off from peak PAE. Such high efficiency is attained due to low combiner losses of 0.5 dB, which is less than half of what can be achieved with a conventional Doherty combiner. Furthermore, an asymmetric Doherty PA is reported that is based on low loss output Doherty combiner and uses a 2-stack cell in the main path and a 4-stack cell in the peaking path, thus improving efficiency at more than 6 dB back-off and achieving high output power. In addition, a compact modeling approach for large, parasitic-extracted PA transistors is presented, which considerably reduces simulation time and accelerates developments of CMOS PAs. A typical time-division duplex (TDD) transmit/receive (T/R) mm-wave front-end comprises a power amplifier, a low noise amplifier (LNA), an antenna switch, and appropriate passive matching and combining networks. In this thesis, a synthesis methodology is proposed that minimizes the overall losses by combining the PA output and the LNA input matching networks together with the T/R switch into one network. The technique improves mm-wave transceiver performance in terms of PA efficiency and LNA noise figure (NF). The proposed T/R combiner can achieve high linearity and can handle large PA output voltage swings. The architecture can be implemented in any process which provides high integration capability. A Ka-band implementation is demonstrated in CMOS SOI that includes a high power, 4-stack based PA and an inductively source degenerated, cascode based LNA. Within the front-end, the PA achieves saturated output power of 23.6 dBm with peak PAE of 28%, while the LNA achieves NF of 3.2 dB. Finally, in frequency division duplex (FDD) systems, spurious emissions from the transmitter (TX) can fall onto the receive (RX) band and lead to significant receiver desensitization. This dissertation proposes a DSP based solution that relies on a linear auxiliary receiver to cancel the RX band noise from the received signal. This technique allows reduction of duplexer rejection requirements in the RX band, and reduction of insertion loss in the TX band, thus, resulting in high PA efficiency and smaller duplexer footprint. PA architectures that inherently have high receive band noise (envelop tracking and digital PAs) can substantially benefit from this technique. More than 22 dB improvement in the signal to noise ratio (SNR) is shown without the presence of desired signal at the antenna.

This book was released on 2009 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this dissertation is on the development of high power, monolithically integrated amplifiers for millimeter-wave wireless communication systems utilizing InP DHBT devices. Due to the ever increasing bandwidth requirements of wireless communications systems, the large amount of spectrum available at millimeter-wave frequencies is making these frequency bands increasingly more relevant. This spurs the need for the development of the various circuit and system building blocks required for implementation of reliable communications systems taking advantage of these wide-band channels. The challenges posed in the development of millimeter-wave power amplifier design range from device model development, to circuit design aspects and also compact power combiner design. The large signal nature of power amplifier operation requires device models, which accurately capture the nonlinear and heating effects of the devices used in the power amplifier design. Techniques for the measurement and model extraction of InP DHBT devices for millimeter-wave applications are discussed in detail. As part of the design of a compact millimeter-wave power amplifier, the optimum design of thermal ballasting networks and cascode termination impedances are described.

This book was released on 2018 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the race to next-generation millimeter-wave (mm-wave) fifth-generation (5G) wireless technology, implementation of highly power-efficient transceivers has become an important research topic. Particularly, the design of high-efficiency and frequency-reconfigurable power amplifier (PA) in complementary-metal-oxide-semiconductor (CMOS) technology is of paramount importance as it enables longer battery life and improved thermal management at a low cost in smart portable-devices while supporting multi-standard 5G communications such as 28GHz, 37-40GHz etc. Simultaneously, a PA with large-bandwidth and high-linearity is highly desirable for 5G mobile communications as it can cover multiple wideband-channels with high-order complex-modulation schemes (i.e., 64/512-quadrature-amplitude-modulation (QAM)) while ensuring robust performances against process-voltage-temperature variations. So far, traditional PA architectures have failed to address these critical design challenges and performance goals. This dissertation presents three new architectures for the design of highly-efficient, highly-linear, wideband and frequency-reconfigurable CMOS PAs for mm-wave 5G cellular communications with 15-16dBm of output-power. First, a 40% power-added-efficiency (PAE) frequency-reconfigurable PA with a tunable gate-drain neutralization at 24GHz and 28GHz is investigated in 65nm CMOS. This is the very first demonstration of a frequency-reconfigurable CMOS PA at mm-wave frequencies using tunable-inductor and tunable-transformer. Second, a 25-35GHz neutralized Continuous Class-F (CCF) CMOS PA achieving 26% modulation-PAE at 1.5Gbps and 46.4% peak-PAE is developed. This design is the very first demonstration of a CCF PA at mm-wave, and the reported measured 46.4% PAE is the highest PAE among mm-wave CMOS PAs to-date. Finally, a 28GHz 41%-PAE linear CMOS PA architecture using a transformer-based amplitude-to-phase (AM-PM) pre-distortion correction technique for 5G is investigated and developed. The proposed linearizer adopts a transformer-based self-compensated pre-distortion network to correct a detrimental AM-PM distortion due to non-linear gate-source capacitance (Cgs) in CMOS PAs. This linearization method mitigates the large-gain reduction problem in traditionally used capacitor-based linearization approaches while consuming no extra-power or introducing additional circuity. Subsequently, significant improvement in modulated-PAE and linearity is achieved. These three PA architectures provide distinct merits of advancing the knowledge of high-linearity, high-efficiency, wideband and frequency-reconfigurable fully-integrated CMOS PA design at mm-wave for next-generation multi-Gbps 5G communications by presenting original circuit topologies, fully supported by analytical-equations, chip-fabrication and comprehensive large-signal measurement results.

Download or read book Power-Combining Techniques for Millimeter-wave Silicon Power Amplifiers written by Jefy Alex Jayamon and published by . This book was released on 2017 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emerging millimeter-wave applications, including high speed wireless communication using 5G standards, favor silicon technologies, both CMOS and SiGe, for transceiver design, due to the high level of integration at reduced cost and availability of high speed transistors. Efficient, linear and reliable high power amplifiers with broad bandwidth are needed at the transmitter front-ends to enable high data rate links at long distances. But the low breakdown voltage of CMOS FETs due to gate length scaling and other transistor non-idealities make the design of high power mm-wave amplifiers in deeply scaled CMOS nodes difficult. Circuit techniques like FET stacking provide a compact and efficient way of implementing high power mm-wave amplifiers reliably. Other power combining techniques such as on-chip and spatial power combining can be used along with FET stacking to achieve even higher output power levels. This thesis investigates the design of high power mm-wave power amplifiers at frequencies from 28 GHz to 94 GHz, using multiple power combining techniques. This work extends the use of FET stacking for high power PA design to 94 GHz. A 3-stack PA designed in 45 nm CMOS SOI with 17 dBm output power and 9% efficiency is presented. Using this PA as front-end, a CMOS PA-antenna array is designed, to additionally provide spatial power combining. The CMOS chip has a 2 x 4 array of pseudo-differential power amplifiers along with the signal distribution networks and pre-drivers. A quartz wafer with a 2 x 4 array of differential microstrip antennas deposited on it is placed on top of the CMOS chip, electromagnetically coupled to the PA outputs on the CMOS chip. The spatially power combined PA-antenna array achieved a measured equivalent isotropic radiated power (EIRP) of 33 dBm and an estimated output power of 24 dBm at 94 GHz. Modulated data measurements at 3 Gbps (375 MS/s, 256 QAM) speed using digital pre-distortion are demonstrated with the PA-antenna array. A novel layout style is introduced for stacked FET design at low mm-wave frequencies. A small multi-finger FET is laid out with fingers connected in series to create the stacked FET. The gate capacitors are realized around the FET with the back-end-of-line metal available in the CMOS process. Multiple multigate cells are interconnected to implement the stacked FET PA. A PA designed in this style in 45 nm CMOS SOI process achieved 24.8 dBm of output power and 29% PAE at 28 GHz with high reliability. This PA is very broadband and linear as shown by the modulated data measurements achieving a data rate of 36 Gbps (6 GS/s, 64 QAM) at 14 dBm with 9.3% PAE, with no digital predistortion. NFETs and PFETs available in nano-scale CMOS processes are compared and it is shown that in deeply scaled processes, PMOS devices are a viable alternative to NFETs due to their cut-off frequencies similar to those of NFETs, and higher breakdown voltages than NFETs. The first exclusively PMOS mm-wave PA design is reported. This 3-stack PA, made in 32 nm CMOS SOI process, achieved a maximum output power of 19.6 dBm and maximum efficiency of 24% at 78 GHz. All the designs reported in this thesis achieved either the highest output power or the highest PAE for a CMOS PA at their respective frequencies.
