Book A CMOS Ultra wideband Differential Low Noise Amplifier

Download or read book A CMOS Ultra wideband Differential Low Noise Amplifier written by Timothy Bryan Merkin and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, a CMOS Ultra-wideband (UWB) Low noise Amplifier (LNA) was designed and simulated. In the design, specific architecture decisions were made in consideration of ultimately including this LNA in a system-on-chip implementation of an Ultra-wideband communication system. The basic architecture of the LNA designed herein exhibits a differential amplifier core with active input and output impedance matching, minimizing the number of expensive space consuming passive inductors necessary for passive impedance matching networks. The LNA maintains a gain of 16.4dB with a +/-0.25 dB ripple over the band of 3.1-6.2GHz. Despite the use of an active input matching stage, the LNA achieved a noise figure ranging from 3.6-3.9 dB over the band of operation. The input active matching stage (common-gate) maintained a less than -10dB reflection coefficient, matching successfully with 50O over the band of 3-12GHz. The output active matching stage (source-follower) maintained a less than 10dB reflection coefficient, also matching successfully with 50O, but maintaining the acceptable reflection coefficient over the band of 3-17GHz.

Book Wideband Low Noise Amplifiers Exploiting Thermal Noise Cancellation

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.

This book was released on 2014-05-21 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, down scaling in CMOS advanced technologies has provided high performance in the digital circuits and reduced cost thereby meeting to a large extent the increasing demand of wireless communication products. With this technology advancement, the unity-current gain frequency of CMOS technology is now over several tens of GHz making the realization of system on-chip solution possible which turns to further reduced cost. The concept of the RFIC design needed for the design of low noise amplifier such as gain, noise, stability, linearity, power consumption etc is discussed in the report. An overview has been given on different LNA architecture, their advantages and disadvantages have also been discussed.The designed circuit is simulated with the help of specture simulator from cadence design system using UMC .18um CMOS technology. After the simulation we got the simulated result of low noise amplifier as forward voltage gain(S21) of 18.53dB, noise figure is 1.8dB and minimum noise figure is 1.6dB, input reflection coefficient (S11) is -24dB, output reflection coefficient(S22) is -15dB, stability factor (Kf) is 4, IIP3 -10 dBm by using power supply voltage of 1.8v.

Book Design of Low Noise Amplifier for Ultra wideband Applications

Download or read book Design of Low Noise Amplifier for Ultra wideband Applications written by Danh T. Vo and published by . This book was released on 2009 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent surge in the demand for low power portable wireless electronics that can offer extremely high data rates has resulted in much active research in Ultra-Wideband (UWB) systems. UWB is widely recognized as a promising technology for high data rate, short-range applications with precise time resolution and high energy efficiency. All these benefits originate from the wideband characteristic of the transmitted/received impulse signals in an UWB system. With current technology, UWB can offer data rates up to 480 Mbps and its operational frequency spectrum is between 3.1 and 10.6 GHz. However, the wideband operation of UWB systems imposes many design challenges that have not been explored before in the traditional narrowband ones. This research is focused on the analysis and design of a low noise amplifier (LNA) for UWB applications. First, two popular narrowband topologies based on inductively degenerated common-source and common-gate configurations are introduced. A comparison between these two topologies is also presented. Then, several wideband LNA topologies are presented and analyzed to determine their suitability for wideband operation. The main emphasis is on input matching, voltage gain, noise figure, and process variation tolerance. Finally, a design procedure is proposed. Examples of applying this procedure to implement a single-ended and differential multistage LNA in 65 nm CMOS process are also given. Both LNAs are designed to have a gain of at least 45 dB, a noise figure of less than 8 dB and an S11 of better than -10 dB while drawing less than 10 mA from a 1.3 V power supply. The LNA's operating frequency is 8.5 GHz.

Book An Ultra Wide Band CMOS Low Noise Amplifier Design

Download or read book An Ultra Wide Band CMOS Low Noise Amplifier Design written by Nahusha Bhadravati Mohankumar and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An RF ultra wide band low noise amplifier designed for the frequency range of 12-18 GHz of operation is presented in this paper. The low noise amplifier is designed using the state-of-the-art complementary metal oxide semiconductor 45 nm technology. Berkeley's Predictive Technology Model (PTM) is used to generate a fairly accurate mathematical model and the SPICE data is implemented into the BSIM 4 version of the Advanced Design Systems (ADS) program. The low noise design strategy is mainly based on the analysis of high frequency CMOS operation. This LNA has two stages: the first stage is a RL feedback amplifier with an inductive load, and the second stage is a RC feedback amplifier with an inductive load. High frequency small signal MOSFET models with shunt-shunt feedback are used to determine the input impedance, output impedance and gain equations governing this circuit. Simulation results of this two stage feedback amplifier demonstrate a gain of 19 dB over a 6 GHz bandwidth, high linearity, and a low noise figure-less than 2.4 dB. This is a low voltage high current amplifier which requires a supply voltage of simply 0.5 V and has low power consumption (~13.5 mW).

Book Low Noise Wide Band Amplifiers in Bipolar and CMOS Technologies

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.
