This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing demand for higher data rates and the crowding of the cellular bands below 3 GHz, researchers are looking to the millimeter-wave frequency spectrum to define the next generation of mobile broadband communications. One of the biggest challenges in implementing a millimeter-wave solution is the low efficiency of commercially available millimeter-wave power amplifiers. Furthermore, the monolithic millimeter-wave integrated circuit (MMIC) power amplifiers also need to have high power with reasonable gain, good linearity and maintain a compact chip size. In Chapter 1 and Chapter 2 of this dissertation, a compact high efficiency Ka-band power amplifier and a highly linear amplifier using second harmonic injection will be demonstrated. The requirements are even more stringent when the amplifiers are deployed in wireless systems that have high peak to average power ratio (PAPR). Among the most popular solutions to achieve high efficiency at power back-off is the Doherty architecture. Thus far, Doherty power amplifiers have been primarily implemented in the spectrum below 3 GHz for cellular base stations. Very few millimeter-wave Doherty PA’s have been reported to date. The conventional Doherty architecture has several inherent drawbacks that cause low efficiency, occupy large chip size and limit the performance bandwidth. Therefore, in our work, we propose four different Doherty amplifier topologies improve the DPA performance: 1) An ultra-compact Doherty amplifier using 3-dimensional broadside coupler 2) A wideband reconfigurable Doherty amplifier 3) A high power density stacked-FET Doherty power amplifier with asymmetrical gate bias 4) A high efficiency asymmetrical Doherty power amplifier using novel load modulation scheme based on load-pull data. All the proposed DPAs are fabricated in a 0.15-[mu]m enhancement mode (E-mode) Gallium Arsenide (GaAs) process. The proposed techniques and experimental results will be discussed in Chapter 3, 4, 5 and 6.The content of this dissertation is a compilation of 18 manuscripts, all of which I am the author or co-author. The titles, publishers and publication dates of the manuscripts are listed on page xii and xiii in this dissertation.

Book Synopsis Reconfigurable RF Power Amplifiers on Silicon for Wireless Handsets by : Laurent Leyssenne
Download or read book Reconfigurable RF Power Amplifiers on Silicon for Wireless Handsets written by Laurent Leyssenne and published by Springer Science & Business Media. This book was released on 2011-01-11 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reconfigurable RF Power Amplifiers on Silicon for Wireless Handsets is intended to designers and researchers who have to tackle the efficiency/linearity trade-off in modern RF transmitters so as to extend their battery lifetime. High data rate 3G/4G standards feature broad channel bandwidths, high dynamic range and critical envelope variations which generally forces the power amplifier (PA) to operate in a low efficiency “backed-off” regime. Classic efficiency enhancement techniques such as Envelope Elimination and Restoration reveal to be little compliant with handset-dedicated PA implementation due to their channel-bandwidth-limited behavior and their increased die area consumption and/or bill-of-material. The architectural advances that are proposed in this book circumvent these issues since they put the stress on low die-area /low power-consumption control circuitry. The advantages of silicon over III/V technologies are highlighted by several analogue signal processing techniques that can be implemented on-chip with a power amplifier. System-level and transistor-level simulations are combined to illustrate the principles of the proposed power adaptive solutions. Measurement on BICMOS demonstrators allows validating the functionality of dynamic linearity/efficiency management. In Reconfigurable RF Power Amplifiers on Silicon for Wireless Handsets, PA designers will find a review of technologies, architectures and theoretical formalisms (Volterra series...) that are traditionally related to PA design. Specific issues that one encounters in power amplifiers (such as thermal / memory effects, stability, VSWR sensitivity...) and the way of overcoming them are also extensively considered throughout this book.

Book Synopsis Highly Efficient and Linear Reconfigurable Mm-Wave CMOS Power Amplifiers for 5g Mobile Communications by : Sheikh Nijam Ali
Download or read book Highly Efficient and Linear Reconfigurable Mm-Wave CMOS Power Amplifiers for 5g Mobile Communications written by Sheikh Nijam Ali and published by . 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.

Book Synopsis Highly Linear Integrated Wideband Amplifiers by : Henrik Sjoland
Download or read book Highly Linear Integrated Wideband Amplifiers written by Henrik Sjoland and published by Springer Science & Business Media. This book was released on 1999-01-31 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highly Linear Integrated Wideband Amplifiers: Design and Analysis Techniques for Frequencies from Audio to RF deals with the complicated issues involved in the design of high-linearity integrated wideband amplifiers for different operating frequencies. The book demonstrates these principles using a number of high-performance designs. New topologies for high linearity are presented, as well as a novel method for estimating the intermodulation distortion of a wideband signal. One of the most exciting results presented is an enhanced feedback configuration called feedback boosting that is capable of very low distortion. Also important is a statistical method for relating the intermodulation distortion of a wideband signal to the total harmonic distortion (THD) of a single tone. The THD, as opposed to the intermodulation distortion of the wideband signal, is easy to measure and use as a design parameter. Three different applications where high linearity is needed are identified, namely audio power amplifiers, wideband IF amplifiers and RF power amplifiers. For these applications high-performance integrated amplifier designs using novel topologies are presented together with measurement results. The audio amplifiers are built in CMOS and are capable of driving 8Omega loudspeaker loads directly without using any external components. One of the designs can operate on a supply voltage down to 1.5V. Both bipolar and CMOS wideband IF amplifiers are built; they are fully differential and have linearity from DC to 20 MHz. Finally, an RF power amplifier is built in CMOS, without using inductors, in order to investigate what performance can be achieved without them. Highly Linear Integrated Wideband Amplifiers: Design and Analysis Techniques for Frequencies from Audio to RF is an excellent reference for researchers and designers of integrated amplifiers, and may be used as a text for advanced courses on the topic.
