Download or read book Millimeter Wave Low Noise Amplifiers written by Mladen Božanić and published by Springer. This book was released on 2017-11-30 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first standalone book that combines research into low-noise amplifiers (LNAs) with research into millimeter-wave circuits. In compiling this book, the authors have set two research objectives. The first is to bring together the research context behind millimeter-wave circuit operation and the theory of low-noise amplification. The second is to present new research in this multi-disciplinary field by dividing the common LNA configurations and typical specifications into subsystems, which are then optimized separately to suggest improvements in the current state-of-the-art designs. To achieve the second research objective, the state-of-the-art LNA configurations are discussed and the weaknesses of state-of the art configurations are considered, thus identifying research gaps. Such research gaps, among others, point towards optimization – at a systems and microelectronics level. Optimization topics include the influence of short wavelength, layout and crosstalk on LNA performance. Advanced fabrication technologies used to decrease the parasitics of passive and active devices are also explored, together with packaging technologies such as silicon-on-chip and silicon-on-package, which are proposed as alternatives to traditional IC implementation. This research outcome builds through innovation. Innovative ideas for LNA construction are explored, and alternative design methodologies are deployed, including LNA/antenna co-design or utilization of the electronic design automation in the research flow. The book also offers the authors’ proposal for streamlined automated LNA design flow, which focuses on LNA as a collection of highly optimized subsystems.

Download or read book The Design Methodology and Optimization of Varactors Based Tunable Matching Network for Power Amplifiers with Load Adaptation Technique written by Chun-Ju Yang and published by . This book was released on 2011 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This thesis presents two tunable matching network designs relying on varactors. The matching network should provide and instantaneous optimized impedance according to different power levels of the power amplifier. The matching networks are designed for an high efficiency class B power amplifier operating at 2 G Hz. Two topologies for the load matching network are considered in this thesis: the Pi network and the T network. The varactors are integrated as part of the load network. By changing the biasing voltages on the varactors, the value of capacitors can be varied and the output impedance modified. The design procedure followed consists in determining the design parameters yielding the maximum load impedance range that can be provided by the network. The major research steps followed include (1) the computational algorithm development, (2) ADS simulations, (3) circuit fabrication and (4) measurements.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a systematic design methodology for millimeter-wave, low noise amplifiers (LNAs). It focuses on the inductively--leaded SiGe HBT cascodc LNA topology. Three LNAs operating at 50 and 65 GHz are fabricated in 0.18mum SiGe BiCMOS technology to validate the proposed methodology. The measured LNA performance agrees well With simulations and is close to the theoretical limit in the given technology. Several of the LNA low-noise design techniques are applied to the design of a 65-GHz receiver integrating an LNA, a down-conversion mixer, a full-rate VCO, and an IF amplifier. The fabricated receiver has a gain of 24 dB and a noise figure of 12 dB. Using compact on-chip inductors, the IC occupies an area of 0.6 mm2, several times smaller than similar published receivers. To the best of the author's knowledge, it is the first millimeter-wave silicon receiver to integrate the VCO on-chip.
Download or read book Wideband Low Noise Amplifiers Exploiting Thermal Noise Cancellation written by Federico Bruccoleri and published by Springer. This book was released on 2008-11-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low Noise Amplifiers (LNAs) are commonly used to amplify signals that are too weak for direct processing for example in radio or cable receivers. Traditionally, low noise amplifiers are implemented via tuned amplifiers, exploiting inductors and capacitors in resonating LC-circuits. This can render very low noise but only in a relatively narrow frequency band close to resonance. There is a clear trend to use more bandwidth for communication, both via cables (e.g. cable TV, internet) and wireless links (e.g. satellite links and Ultra Wideband Band). Hence wideband low-noise amplifier techniques are very much needed. Wideband Low Noise Amplifiers Exploiting Thermal Noise Cancellation explores techniques to realize wideband amplifiers, capable of impedance matching and still achieving a low noise figure well below 3dB. This can be achieved with a new noise cancelling technique as described in this book. By using this technique, the thermal noise of the input transistor of the LNA can be cancelled while the wanted signal is amplified! The book gives a detailed analysis of this technique and presents several new amplifier circuits. This book is directly relevant for IC designers and researchers working on integrated transceivers. Although the focus is on CMOS circuits, the techniques can just as well be applied to other IC technologies, e.g. bipolar and GaAs, and even in discrete component technologies.

This book was released on 2023-10-11 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive knowledge, aimed at practicing integrated circuit design engineer or researcher, to learn and design a low noise amplifier (LNA) for single and multiband applications. The content is structured in a way so that even a beginner can follow the design method easily. This book features the following characteristics: different types of LNA designs (with key building blocks) are discussed, and detailed analysis is given for each LNA design, which covers from the fundamental and principal knowledge to the justification of the design approach. Detailed design approaches are using 180 nm and 130nm CMOS technologies, purposely presented in this manner to give exposure to the design of LNA under different technologies. The LNAs in this book are designed for GSM, WCDMA and WLAN standards, but the same method can be used for other frequencies of operation. Comprehensive analyses on the extreme or corner condition effects are highlighted. Besides, detailed derivation of equations relating to the parameters of the LNA’s performance metrics help LNA designers in understanding how the performance metrics of the LNA can be optimized to meet the desired specification. Electromagnetic analyses using Sonnet, an electromagnetic tool able to replace the conventional post-layout simulation with resistance and capacitance parasitic extraction for more accurate frequency performance prediction are presented. The electromagnetic method is proposed to be used in the LNA design as it can accurately predict the LNA’s performance before tape-out for first-pass fabrication. MATLAB codes are provided to generate important S-parameters and noise figure values.

Book excerpt: Advances in electronics have pushed mankind to create devices, ranging from - credible gadgets to medical equipment to spacecraft instruments. More than that, modern society is getting used to—if not dependent on—the comfort, solutions, and astonishing amount of information brought by these devices. One ?eld that has continuously bene?tted from those advances is the radio frequency integrated c- cuit (RFIC) design, which in its turn has promoted countless bene?ts to the mankind as a payback. Wireless communications is one prominent example of what the - vances in electronics have enabled and their consequences to our daily life. How could anyone back in the eighties think of the possibilities opened by the wireless local area networks (WLANs) that can be found today in a host of places, such as public libraries, coffee shops, trains, to name just a few? How can a youngster, who lives this true WLAN experience nowadays, imagine a world without it? This book dealswith the design oflinearCMOS RF PowerAmpli?ers(PAs). The RF PA is a very important part of the RF transceiver, the device that enables wireless communications. Two important aspects that are key to keep the advances in RF PA design at an accelerate pace are treated: ef?ciency enhancement and frequen- tunable capability. For this purpose, the design of two different integrated circuits realizedina0. 11μmtechnologyispresented,eachoneaddressingadifferentaspect.

Download or read book Digitally Tunable Low Noise Amplifier written by Mohamed Benmansour and published by . This book was released on 2004 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Low noise amplifiers are classified into two categories: Wideband low noise amplifiers and Narrowband low noise amplifiers. Wideband LNAs are known for achieving a poor noise performance. On the other hand, the noise performance of the narrowband amplifiers is good but only over a small frequency range. This constraint made their use restricted to certain applications, such as cellular phone applications (superheterodyne architecture), where a single operational frequency is needed. This thesis introduces a new low noise amplifier topology that provides a high selectivity and a low noise figure over a wide frequency range. The digitally tunable low noise amplifier can be implemented in narrowband applications as well as broadband applications, This thesis discusses in detail the design of the DTLNA. A detailed noise analysis is also discussed in this work. The noise analysis includes the effect of induced gate noise in CMOS, which is rarely cited but nonetheless of fundamental importance in establishing the limits of achievable noise performance. In addition, this thesis demonstrates the performance results of the digitally tunable low noise amplifier. These results prove that the overall performance of the DTLNA surpasses the performance of both wideband and narrowband amplifiers"--Abstract.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent enthusiasm for the Internet of Objects as well as for satellite communications leads to the need for high-performance radio-frequency (RF) communication systems. In order to meet the constraints of the mass market, these systems must be compact and be as low power as possible. Beside, they are expected to address multiple communication standards and to adjust their performance to the environment, still in order to reduce the size and the power consumption. Currently, many works focus on the development of low-noise amplifiers (LNA), the most critical block of RF receivers. To address this purpose, the goal is to design multi-mode and multi-standard receivers. Hence, LNAs require design flows that can adapt to the different technologies and topologies in order to meet any given set of specifications. This thesis aims at the development of simple and accurate design methodologies for the implementation of low-noise amplifiers.The first proposed methodology is dedicated to the implementation of a LNA in COTS technology for spatial applications. This LNA offers a broadband matching to address several standards. It is designed to be part of an RF receiver for nano-satellites. Thus, the latter is first studied in order to determine the specifications based on the standards of the targeted applications.The second methodology is dedicated to the implementation of LNAs in CMOS technology for any kind of applications. This methodology is first illustrated with basic topologies and then applied to an highly linear inductorless LNA. The design methodology also enables a fair comparison between the topologies and also CMOS technologies, even the most advanced ones such as the 28 nm FDSOI.Finally, reconfigurability is added to the inductorless LNA, to address several standards while retaining the optimum sizing given by the previously introduced methodology. Indeed, the size and polarization of each transistor are digitally controlled in order to adjust the LNA's performance to a given standard. Furthermore, the study of N-path filters combined with the proposed LNA is explored to improve the linearity of the circuit.

Download or read book Distortion Analysis of Analog Integrated Circuits written by Piet Wambacq and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis and prediction of nonlinear behavior in electronic circuits has long been a topic of concern for analog circuit designers. The recent explosion of interest in portable electronics such as cellular telephones, cordless telephones and other applications has served to reinforce the importance of these issues. The need now often arises to predict and optimize the distortion performance of diverse electronic circuit configurations operating in the gigahertz frequency range, where nonlinear reactive effects often dominate. However, there have historically been few sources available from which design engineers could obtain information on analysis tech niques suitable for tackling these important problems. I am sure that the analog circuit design community will thus welcome this work by Dr. Wambacq and Professor Sansen as a major contribution to the analog circuit design literature in the area of distortion analysis of electronic circuits. I am personally looking forward to hav ing a copy readily available for reference when designing integrated circuits for communication systems.
