Available in PDF, EPUB and Kindle. Book excerpt: IEEE 802.15 High Rate Alternative PHY task group (TG3a) is working to define a protocol for Wireless Personal Area Networks (WPANs) which makes it possible to attain data rates of greater than 110Mbps. Ultra Wideband (UWB) technology utilizing frequency band of 3.168 GHz - 10.6 GHz is an emerging solution to this with data rates of 110, 200 and 480 Mbps. Initially, UWB mode I devices using only 3.168 GHz - 4.752GHz have been proposed. Low Noise Amplifier (LNA) and I-Q mixers are key components constituting the RF front-end. Performance of these blocks is very critical to the overall performance of the receiver. In general, main considerations for the LNA are low noise, 50 broadband input matching, high gain with maximum flatness and good linearity. For the mixers, it is essential to attain low flicker noise performance coupled with good conversion gain. Proposed LNA architecture is a derivative of inductive source degenerated topology. Broadband matching at the LNA output is achieved using LC band-pass filter. To obtain high gain with maximum flatness, an LC band-pass filter is used at its output. Proposed LNA achieved a gain of 15dB, noise figure of less than 2.6dB and IIP3 of more than-7dBm. Mixer is a modified version of double balanced Gilbert cell topology where both I and Q channel mixers are merged together. Frequency response of each sub-band is matched by using an additional inductor, which further improves the noise figure and conversion gain. Current bleeding scheme is used to further reduce the low frequency noise. Mixer achieves average conversion gain of 14.5dB, IIP3 more than 6dBm and Double Side Band (DSB) noise figure less than 9dB. Maximum variation in conversion gain is desired to be less than 1dB. Both LNA and mixers are designed to be fabricated in TSMC 0.18 [mu]m CMOS technology.

Available in PDF, EPUB and Kindle. Book excerpt: Ultra-Wideband (UWB) technology has become one of the hottest topics in wireless communications, for it provides cost-effective, power-efficient, high bandwidth solution for relaying data in the immediate area (up to 10 meters). This work demonstrates two different solutions for the RF front-end designs in the UWB receivers, one is distributed topology, and the other is based on traditional lumped element topology. The distributed amplifier is one of the attractive candidates for UWB Low Noise Amplifier (LNA). The design, analysis and operation of the distributed amplifiers will be presented. A distributed amplifier is designed with Coplanar Waveguide (CPW) transmission lines in 0.25-[micron] CMOS process for time domain UWB applications. New design techniques and new topologies are developed to enhance the power-efficiency and reduce the chip area. A compact and high performance distributed amplifier with Patterned Grounded Shield (PGS) inductors is developed in 0.25-[micron] CMOS process. The amplifier has a measurement result of 7.2dB gain, 4.2-6dB noise figure, and less than -10dB return loss through 0-11GHz. A new distributed amplifier implementing cascade common source gain cells is presented in 0.18-[micron] CMOS. The new amplifier demonstrates a high gain of 16dB at a power consumption of 100mW, and a gain of 10dB at a low power consumption of 19mW. A UWB LNA utilizing resistive shunt feedback technique is reported in 0.18-[micron] CMOS process. The measurement results of the UWB LNA demonstrate a maximum gain of 10.5dB and a noise figure of 3.3-4.5dB from 3-9.5GHz, while only consuming 9mW power. Based on the distributed amplifier and resistive shunt-feedback amplifier designs, two UWB RF front-ends are developed. One is a distributed LNA-Mixer. Unlike the conventional distributed mixer, which can only deliver low gain and high noise figure, the proposed distributed LNA-Mixer demonstrates 12-14dB gain,4-5dB noise figure and higher than 10dB return loss at RF and LO ports over 2-16GHz. To overcome the power consumption and chip area problems encountered in distributed circuits, another UWB RF front-end is also designed with lumped elements. This front-end, employing resistive shunt-feedback technique into its LNA design, can achieve a gain of 12dB and noise figure of 8-10dB through 3-10GHz, the return loss of less than -10dB from 3- 10GHz at RF port, and less than -7dB at LO port, while only consuming 25mA current from 1.8V voltage supply.

Available in PDF, EPUB and Kindle. Book excerpt: Chipless RFID Reader Design for Ultra-Wideband Technology: Design, Realization and Characterization deals with the efficient design of Field Programmable Gate Array (FPGA) based embedded systems for chipless readers, providing a reading technique based on polarization diversity that is shown with the aim of reading cross-polarized, chipless tags independently from their orientation. This approach is valuable because it does not give any constraint at the tag design level. This book presents the state-of-the-art of chipless RFID systems, also providing useful comparisons. The international regulations that limit the UWB emission are taken into consideration, along with design guidance. Two designed, realized, and characterized reader prototypes are proposed. Sampling noise reduction, reading time, and cost effectiveness are also introduced and taken into consideration. - Presents the design, realization and characterization of chipless RFID readers - Provides concepts that are designed around a FPGA and its internal architecture, along with the phase of optimization - Covers the design of a novel pulse generator

Download or read book Direct Conversion RF Front end Implementation for Ultra wideband UWB and GSM WCDMA Dual band Applications in Silicon based Technologies written by Yunseo Park and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on wideband circuit design and implementation issues up to 10GHz based on the direct conversion architecture in the CMOS and SiGe BiCMOS technologies. The dissertation consists of two parts: One, implementation of a RF front-end receiver for an ultra-wideband system and, two, implementation of a local oscillation (LO) signal for a GSM/WCDMA multiband application. For emerging ultra-wideband (UWB) applications, the key active components in the RF front-end receiver were designed and implemented in 0.18um SiGe BiCMOS process. The design of LNA, which is the critical circuit block for both systems, was analyzed in terms of noise, linearity and group delay variation over an extemely wide bandwidth. Measurements are demonstrated for an energy-thrifty UWB receiver based on an MB-OFDM system covering the full FCC-allowed UWB frequency range. For multiband applications such as a GSM/WCDMA dual-band application, the design of wideband VCO and various frequency generation blocks are investigated as alternatives for implementation of direct conversion architecture. In order to reduce DC-offset and LO pulling phenomena that degrade performance in a typical direct conversion scheme, an innovative fractional LO signal generator was implemented in a standard CMOS process. A simple analysis is provided for the loop dynamics and operating range of the design as well as for the measured results of the factional LO signal generator.

The second chapter provides the basics of CMOS RFICs needed for the design of the UWB RFIC transmitter and receiver presented in this book. It includes the design fundamentals, lumped and distributed elements for RFIC, layout, post-layout simulation, and measurement. The third chapter discusses the basics of UWB systems including UWB advantages and applications, signals, basic modulations, transmitter and receiver frontends, and antennas.
