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.

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).

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.

Available in PDF, EPUB and Kindle. Book excerpt: The THz band (0.1 - 10 THz) holds several applications such as high-speed communication,3D imaging radars, and spectroscopy. A high-sensitivity receiver is crucial for fully utilizing this broad untapped spectrum. Advancements in silicon technologies now enable transistors with maximum oscillation frequency (fmax) beyond 400 GHz, enabling silicon THz ICs. This thesis presents two ultra-wideband low noise amplifiers in the THz band, designed using silicon technologies. Several key concepts are discussed, such as optimal bias selection, passive circuit modeling, bandwidth enhancement, circuit-EM co-simulation approaches, and THz probe-based testing. The first design is a 7-stage cascaded common-emitter LNA with more than 80 GHz of 3-dB bandwidth, covering the entire WR5 frequency band (140-220 GHz). It has a measured peak gain of 15.5 dB and a simulated NF of 6.8 dB at 180 GHz, with 46 mW DC power consumption, and is implemented in the IHP 130 nm SiGe BiCMOS process. The second design is a cascaded 12-stage common-emitter LNA with 45 GHz of 3-dB bandwidth, from 190 GHz to 235 GHz. This design achieves a peak gain of 216 GHz, a sub 10 dB noise figure, DC power consumption of 19.9 mW, and is implemented in GlobalFoundries 22nm FDSOI process.
