Book Description
The low-cost low-power complementary metal-oxide semiconductor (CMOS) ultra wideband (UWB) transmitter and receiver front-ends based on impulse technology were developed. The CMOS UWB pulse generator with frequency-band tuning capability was developed, which can generate both impulse and monocycle pulse signals with variable pulse durations. The pulse generator integrates a tuning delay circuit, a square-wave generator, an impulse-forming circuit, and a pulse-shaping circuit in a single chip. When integrated with the binary phase shift keying (BPSK) modulator, the transmitter front-end can generate a positive impulse with 0.8 V, negative impulse with 0.7 V, as well as the positive/negative monocycle pulse with 0.6 -- 0.8 V, all with tunable pulse durations. The UWB receiver front-end including the template pulse generator, low noise amplifier (LNA), and multiplier was developed. The cascoded common-source inductively degenerated LNA, with extended ultra-wideband ladder matching network, as well as shunt-peaking topology, was selected to form the impulse-type UWB LNA. The structure-optimized and patterned ground shield (PGS) inductors were also studied and used in LNA design to improve the LNA performance. The maximum gain of 12.4 dB was achieved over the band. For the 3-dB bandwidth, 2.6 -- 9.8 GHz was achieved. The average noise figure of 5.8 dB was achieved over the entire UWB band of 3.1-10.6 GHz. The UWB multiplier based on the transconductor multiplier structure was investigated, with the shunt-peaking topology applied to achieve the pole-zero cancellation and extend the multiplier bandwidth from 2 GHz to 10 GHz. A low-cost, compact, easy-to-manufacture coplanar UWB antenna was developed that is omni-directional, radiation-efficient and has a stable UWB response. It covers the entire UWB frequency range of 3.1 - 10.6 GHz, with the return loss better than 18-dB. This novel uniplanar antenna was integrated with the developed CMOS tunable pulse generator to form the UWB transmitter front-end module. This UWB module can transmit the monocycle pulses and the signals having shape similar to the first derivative of the monocycle pulses, all with the tunable pulse durations. The proposed UWB front-ends have the potential application in short-range communication, GPR, and short-range detections.

Book Description
This book presents the design of ultra-wideband (UWB) impulse-based transmitter and receiver frontends, operating within the 3.1-10.6 GHz frequency band, using CMOS radio-frequency integrated-circuits (RFICs). CMOS RFICs are small, cheap, low power devices, better suited for direct integration with digital ICs as compared to those using III-V compound semiconductor devices. CMOS RFICs are thus very attractive for RF systems and, in fact, the principal choice for commercial wireless markets. The book comprises seven chapters. The first chapter gives an introduction to UWB technology and outlines its suitability for high resolution sensing and high-rate, short-range ad-hoc networking and communications. 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. The fourth chapter addresses the design of UWB transmitters including an overview of basic components, design of pulse generator, BPSK modulator design, and design of a UWB tunable transmitter. Chapter 5 presents the design of UWB receivers including the design of UWB low-noise amplifiers, correlators, and a UWB 1 receiver. Chapter 6 covers the design of a UWB uniplanar antenna. Finally, a summary and conclusion is given in Chapter 7.

Book Description
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.

Book Description
Smart energy management, both at design time and at run time, is indispensable in modern radios. It requires a careful trade-off between the system’s performance, and its power consumption. Moreover, the design has to be dynamically reconfigurable to optimally balance these parameters at run time, depending on the current operating conditions. Energy Scalable Radio Design describes and applies an energy-driven design strategy to the design of an energy-efficient, highly scalable, pulsed UWB receiver, suitable for low data rate communication and sub-cm ranging. This book meticulously covers the different design steps and the adopted optimizations: System level air interface selection, architectural/algorithmic design space exploration, algorithmic refinement (acquisition, synchronization and ranging algorithms) and circuit level (RTL) implementation based on the FLEXmodule-concept. Measurement results demonstrate the effectiveness and necessity of the energy-driven design strategy.

Book Description
This book discusses a number of challenges faced by designers of wireless receivers, given complications caused by the shrinking of electronic and mobile devices circuitry into ever-smaller sizes and the resulting complications on the manufacturability, production yield, and the end price of the products. The authors describe the impact of process technology on the performance of the end product and equip RF designers with countermeasures to cope with such problems. The mechanisms by which these problems arise are analyzed in detail and novel solutions are provided, including design guidelines for receivers with robustness to process variations and details of circuit blocks that obtain the required performance level.
