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.

This book was released on 2010 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wideband amplifiers are an important part of analog design, and much effort has been expended in improving them. A popular implementation of a wideband amplifier is to use one or two stages with high gain in one or both stages. An alternative to this method is presented in this work, developed for Metal Oxide Semiconductor (MOS) amplifiers. The new approach, building on previous work in bipolar technology, uses multiple differential MOS stages to achieve similar gain requirements to other wideband amplifiers. It is shown that multiple stages with low gain, if implemented according to the present design method, can lead to better gain-bandwidth product (GBW) than a few stages. As part of the design process, GBW is optimized and current draw is reduced. Derived equations are used to find the ideal device widths of each stage to improve GBW. The amplifier's current draw is reduced through increasing the widths of each successive stage according to a derived, fixed taper factor. Simulation of the resulting amplifier shows that these optimization procedures can improve GBW by 20% or more over a nonoptimized cascaded amplifier.

This book was released on 2017-11-13 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The modern wireless communication systems require modulated signals with wide modulation bandwidth. This, in turns, requires signals with very high dynamic range and peak-to-average power ratio (PAPR). This means that the amplifier in the base-station has to work at a power back-off as large as the dynamic range of the signal, so that the amplifier has a high linearity in this region. For the standard single-stage amplifiers, this large power back-off reduces the efficiency dramatically. In this work, a three-way Doherty power amplifier (DPA) aiming at high power efficiency within a dynamic range of 9.5 dB, is designed and fabricated using partitioning design approach. The partitioning design approach decomposes a complex design task into small-sized, well-controllable, and verifiable subcircuits. This advanced straight forward method has shown very promising results. Using this design approach, a three-way DPA has been designed to demonstrate the advantages of this reliable design technique as well. Based on the design of a single-stage power amplifier and proposing a novel output power combiner, a 6 W three-way DPA has been designed which allows the mandatory load modulation principle in three-way DPA structures to be realized with simpler elements, whereas the design of a standard Doherty combiner would have been very challenging and not practical due to the extremely small value of its characteristic line impedance. The proposed combiner is calculated for a three-way DPA with 2-mm AlGaN/GaN-HEMTs. The simulation result shows a very good load modulation for the amplifier, which confirms the theoretical expectation for a three-way DPA. The efficiency of the designed 6 W three-way DPA at large back-off shows very promising values compared to recently reported amplifiers. The measured IMD3 products confirm the good linearity of the amplifier as well. Accordingly, the proposed power combiner and the design strategy are recommended to be used as the preferred option for designing three-way DPA structures with very high output power.

Available in PDF, EPUB and Kindle. Book excerpt: Since the early days of telecommunication and warfare technologies, the power amplifier has been playing a key role in signal transmission and reception as the transport portal. There are many studies and research fields that are dedicated to a single goal: improving the performance of power amplifiers. The real frequency technique (RFT) and its sister the simplified real technique (SRFT) revolutionized RF power amplifier design by allowing nonlinear treatment of RF components and initiating the use of numerical optimization to analyze and synthesize nonlinear systems. The latest research in amplifier design has been going in this direction as optimization and computation techniques become more advanced and effective in solving highly complex nonlinear systems. The novel bounded performance technique (BPT) is developed to further popularize the use of optimization in power amplifier design. The design process depends on the use of load-pull data, an effective way to characterize nonlinear devices. The method is simple: creating a highly effective cost function for the optimization of the matching network that provides the required performance of the amplifier. Additionally, BPT cost function enables an infinite degree of design freedom that allows the design of complex amplifiers. In this dissertation, the effectiveness and versatility of BPT are demonstrated in the designs of some typical and advanced amplifiers including: a medium bandwidth, an ultra-wide bandwidth, a high-efficiency class-J, a C-band Doherty, a cascade, a configurable, and a multi-band. In each design case, BPT makes the design process feasible and observable. The fabricated amplifiers are all first pass successes and show performance that is on par or exceeds that of prior or contemporary design arts. This research shows that BPT makes the design process of complex amplifiers simpler, less laborious, and more fun. This work contributes to the advancement of modern communication systems in which power amplifiers are the most critical component.
Download or read book Op Amps for Everyone written by Ron Mancini and published by Newnes. This book was released on 2003 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: The operational amplifier ("op amp") is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp. This book is Texas Instruments' complete professional-level tutorial and reference to operational amplifier theory and applications. Among the topics covered are basic op amp physics (including reviews of current and voltage division, Thevenin's theorem, and transistor models), idealized op amp operation and configuration, feedback theory and methods, single and dual supply operation, understanding op amp parameters, minimizing noise in op amp circuits, and practical applications such as instrumentation amplifiers, signal conditioning, oscillators, active filters, load and level conversions, and analog computing. There is also extensive coverage of circuit construction techniques, including circuit board design, grounding, input and output isolation, using decoupling capacitors, and frequency characteristics of passive components. The material in this book is applicable to all op amp ICs from all manufacturers, not just TI. Unlike textbook treatments of op amp theory that tend to focus on idealized op amp models and configuration, this title uses idealized models only when necessary to explain op amp theory. The bulk of this book is on real-world op amps and their applications; considerations such as thermal effects, circuit noise, circuit buffering, selection of appropriate op amps for a given application, and unexpected effects in passive components are all discussed in detail. *Published in conjunction with Texas Instruments *A single volume, professional-level guide to op amp theory and applications *Covers circuit board layout techniques for manufacturing op amp circuits.

This book was released on 2013-04-17 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frequency Compensation Techniques for Low-Power Operational Amplifiers is intended for professional designers of integrated amplifiers, emphasizing low-voltage and low-power solutions. The book bridges the gap between the professional designer's needs and available techniques for frequency compensation. It does so by explaining existing techniques and introducing several new techniques including Hybrid Nested Miller compensation, Multipath Miller Zero cancellation and Multipath Conditionally Stable compensation. All compensation techniques are treated in a stage-number-based order, progressing from a single transistor to circuits with six stages and more. Apart from discussing the mathematical basis of the compensation methods, the book provides the reader with the factual information that is required for practicing the design of integrated feedback amplifiers and many worked out examples. What is more, many bipolar and CMOS operational amplifier realizations, along with their measurement results, prove the effectiveness of the compensation techniques in real-life circuits. The text focuses on low-voltage, low-power integrated amplifiers. Many of the presented bipolar circuits operate at supply voltages down to 1V, while several CMOS amplifiers that function correctly just slightly above this voltage are demonstrated. The lowest measured power consumption amounts to 17muW for a class AB CMOS opAmp with 120dB gain. Despite this attention to low voltage and low power, the frequency compensation strategies provided are universally applicable. The fundamental approach followed leads to efficient compensation strategies that are well guarded against the parameter variations inherent to the mass-fabrication of integrated circuits. The book is essential reading for practicing analog design engineers and researchers in the field. It is also suitable as a text for an advanced course on the subject.
