Book Synopsis Digitally Tunable Low Noise Amplifier by : Mohamed Benmansour
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.

Book Synopsis Wideband Low Noise Amplifiers Exploiting Thermal Noise Cancellation by : Federico Bruccoleri
Download or read book Wideband Low Noise Amplifiers Exploiting Thermal Noise Cancellation written by Federico Bruccoleri and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 191 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.

Book Synopsis Modern HF Signal Detection and Direction Finding by : Jay R. Sklar
Download or read book Modern HF Signal Detection and Direction Finding written by Jay R. Sklar and published by MIT Press. This book was released on 2018-09-25 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed descriptions of detection, direction-finding, and signal-estimation methods, using consistent formalisms and notation, emphasizing HF antenna array sensing applications. Adaptive antenna array technology encompasses many powerful interference suppression approaches that exploit spatial differences among signals reaching a radio receiver system. Today, worldwide propagation phenomenology occurring in the High Frequency (HF) radio regime has made such interference common. In this book, Jay Sklar, a longtime researcher at MIT Lincoln Laboratory, presents detailed descriptions of detection, direction-finding, and signal-estimation methods applicable at HF, using consistent formalisms and notation. Modern electronic system technology has made many of these techniques affordable and practical; the goal of the book is to offer practicing engineers a comprehensive and self-contained reference that will encourage more widespread application of these approaches. The book is based on the author's thirty years of managing MIT Lincoln Laboratory work on the application of adaptive antenna array technologies to the sensing of HF communication signals. After an overview of HF propagation phenomenology, communication signal formats, and HF receiver architectural approaches, Sklar describes the HF propagation environment in more detail; introduces important modulation approaches and signaling protocols used at HF; discusses HF receiver system architectural features; and addresses signal processor architecture and its implementation. He then presents the technical foundation for the book: the vector model for a signal received at an adaptive array antenna. He follows this with discussions of actual signal processing techniques for detection and direction finding, including specific direction-finding algorithms; geolocation techniques; and signal estimation.

Book Synopsis Low-Noise Wide-Band Amplifiers in Bipolar and CMOS Technologies by : Zhong Yuan Chong
Download or read book Low-Noise Wide-Band Amplifiers in Bipolar and CMOS Technologies written by Zhong Yuan Chong and published by Springer Science & Business Media. This book was released on 1990-11-30 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analog circuit design has grown in importance because so many circuits cannot be realized with digital techniques. Examples are receiver front-ends, particle detector circuits, etc. Actually, all circuits which require high precision, high speed and low power consumption need analog solutions. High precision also needs low noise. Much has been written already on low noise design and optimization for low noise. Very little is available however if the source is not resistive but capacitive or inductive as is the case with antennas or semiconductor detectors. This book provides design techniques for these types of optimization. This book is thus intended firstly for engineers on senior or graduate level who have already designed their first operational amplifiers and want to go further. It is especially for engineers who do not want just a circuit but the best circuit. Design techniques are given that lead to the best performance within a certain technology. Moreover, this is done for all important technologies such as bipolar, CMOS and BiCMOS. Secondly, this book is intended for engineers who want to understand what they are doing. The design techniques are intended to provide insight. In this way, the design techniques can easily be extended to other circuits as well. Also, the design techniques form a first step towards design automation. Thirdly, this book is intended for analog design engineers who want to become familiar with both bipolar and CMOS technologies and who want to learn more about which transistor to choose in BiCMOS.
