Download or read book CMOS Low Noise Amplifiers for Single and Multiband Applications: A Comprehensive Design Approach written by Norlaili Mohd Noh, Farshad Eshghabadi, Arjuna Marzuki and published by Penerbit USM. 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 Synopsis Multi-band Reconfigurable RFICs in Si-based Technologies for a Compact and Adaptive RF Front-end by : Asad Ali Nawaz
Download or read book Multi-band Reconfigurable RFICs in Si-based Technologies for a Compact and Adaptive RF Front-end written by Asad Ali Nawaz and published by . This book was released on 2020 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in the wireless communication market have led to the coexistence of several networks such as cellular network, personal area network (PAN), wireless local area network (WLAN), etc. along with several different air interfaces (802.11a, 802.11g, Bluetooth, wireless code division multiple access (WCDMA), etc.). Thus, all the wireless devices need to be compatible with the different communication standards while still keeping similar performance, smaller die area and lower power consumption. The need to enable the "global roaming'' capability between a wide variety of networks operating at different frequencies calls for the development of reconfigurable radio-frequency integrated circuits (RFICs) which can achieve maximum hardware sharing between different standards and across various functions. The objective of this dissertation is to present novel topologies for RF components and blocks that can yield a Si-based frequency-agile RF front-end. The targeted applications for this work are 5G multi-band wireless communication and reconfigurable short/long range phased arrays for automobile radars. However, the concept of the proposed reconfigurable RF elements is generic in nature and can be applied to all emerging applications which require on-chip reconfigurability at microwave and mm-wave frequencies.To demonstrate the concept of a reconfigurable RF front end, a Ka/V band-switchable TRX amplifier is developed in 0.13um BiCMOS SiGe process and a 18-50 GHz receiver is developed in 45nm SOI CMOS process. Unlike the traditional approach for a multi-band radio - where the dedicated single band transceivers composed of fixed RF components are designed and multiplexed with the help of switches - the proposed idea utilizes the switches inside each RF block; thus, adding the reconfigurability inside each block and eliminating the need for separate front-ends. However, the catch in the latter approach is to maintain the RF performance while still being able to save the real estate and power consumption. The proposed Ka/V band-switchable TRX amplifier consists of a band-switchable LNA, a band-switchable PA, and integrated T/R switches which saves a lot of area. The band-switch functionality is realized using thin-film microstrip based shunt stubs with reverse saturated SiGe switches. Design techniques for switch loss reduction and size miniaturizations are presented. This work illustrates that with the optimization of switch loss, appropriate selection of each block between wideband or bandswitching topology and co-design of RF blocks, a highly integrated multi-band transceiver can be designed with the minimal degradation to the RF performance compared to state-of-the-art dedicated single band transceivers. To further explore reconfigurable transceivers, a direct quadrature down-conversion mixer first receiver with active channel select filters has been designed. The receiver supports 200MHz instantaneous RF bandwidth and can be reconfigured to receive any 200 MHz channel within 18-50 GHz frequency range. With the ever-evolving wireless standards like 4G/5G/6G, equipment manufacturers are required to add more functionality into the chips while still maintaining the backward compatibility with previous standards or fallback option to lower frequency bands. A low power, highly integrated, multi-band and multi-standard chipset has thus become a requisite in commercial products. The proposed concept of in-block reconfigurability and the presented design techniques to realize mm-wave frequency reconfigurable transceivers have a huge potential in this regard.
Book Synopsis Design of Reconfigurable Antennas Using Graph Models by : Joseph Costantine
Download or read book Design of Reconfigurable Antennas Using Graph Models written by Joseph Costantine and published by Springer Nature. This book was released on 2022-06-01 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This lecture discusses the use of graph models to represent reconfigurable antennas. The rise of antennas that adapt to their environment and change their operation based on the user's request hasn't been met with clear design guidelines. There is a need to propose some rules for the optimization of any reconfigurable antenna design and performance. Since reconfigurable antennas are seen as a collection of self-organizing parts, graph models can be introduced to relate each possible topology to a corresponding electromagnetic performance in terms of achieving a characteristic frequency of operation, impedance, and polarization. These models help designers understand reconfigurable antenna structures and enhance their functionality since they transform antennas from bulky devices into mathematical and software accessible models. The use of graphs facilitates the software control and cognition ability of reconfigurable antennas while optimizing their performance. This lecture also discusses the reduction of redundancy, complexity and reliability of reconfigurable antennas and reconfigurable antenna arrays. The full analysis of these parameters allows a better reconfigurable antenna implementation in wireless and space communications platforms. The use of graph models to reduce the complexity while preserving the reliability of reconfigurable antennas allow a better incorporation in applications such as cognitive radio, MIMO, satellite communications, and personal communication systems. A swifter response time is achieved with less cost and losses. This lecture is written for individuals who wish to venture into the field of reconfigurable antennas, with a little prior experience in this area, and learn how graph rules and theory, mainly used in the field of computer science, networking, and control systems can be applied to electromagnetic structures. This lecture will walk the reader through a design and analysis process of reconfigurable antennas using graph models with a practical and theoretical outlook.
