This book was released on 2006-01-20 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thanks to the advance of semiconductor and communication technology, the wireless communication market has been booming in the last two decades. It evolved from simple pagers to emerging third-generation (3G) cellular phones. In the meanwhile, broadband communication market has also gained a rapid growth. As the market always demands hi- performance and low-cost products, circuit designers are seeking hi- integration communication devices in cheap CMOS technology. The phase-locked loop frequency synthesizer is a critical component in communication devices. It works as a local oscillator for frequency translation and channel selection in wireless transceivers and broadband cable tuners. It also plays an important role as the clock synthesizer for data converters in the analog-and-digital signal interface. This book covers the design and analysis of PLL synthesizers. It includes both fundamentals and a review of the state-of-the-art techniques. The transient analysis of the third-order charge-pump PLL reveals its locking behavior accurately. The behavioral-level simulation of PLL further clarifies its stability limit. Design examples are given to clearly illustrate the design procedure of PLL synthesizers. A complete derivation of reference spurs in the charge-pump PLL is also presented in this book. The in-depth investigation of the digital CA modulator for fractional-N synthesizers provides insightful design guidelines for this important block.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In an era dominated by the highly demanding wireless communication system, there is a great need for developing small, cheap, and low power RF sub-systems. This demand has lead to significant research on completely integrated transceiver systems. One of the great challenges in an integrated transceiver system is the frequency synthesizer. Frequency synthesizers are usually implemented using a phase locked loop (PLL) and low frequency highly stable crystal oscillator. The spectral purity of a synthesized carrier signal depends on the kind of Voltage Controlled Oscillator (VCO) used. Hence successful implementation of a low phase noise, completely integrated VCO in standard CMOS process is a major step towards implementing a completely integrated transceiver. The best VCO architecture in terms of noise performance is LC-VCO. The aim of the current research is to design a completely integrated 1.8 GHz LC-VCO for a GSM or DCS-1800 receiver in standard CMOS 0.35 [mu]m technology. The major challenge in a completely integrated LC-VCO is to develop an fully integrated inductor. In this research various means of implementing an integrated inductor have been scrutinized and the best feasible among them the on-chip spiral inductor has been analyzed elaborately. The complete design cycle from describing the specification of an inductor to the final layout in Cadence has been described. Also a new symmetrical, highly balanced on-chip inductor has been used in the current design. Another important and the most critical challenge is to implement a very high tuning range, high Q-factor on-chip varactor in standard CMOS process. In this research a new body driven varactor, which is forced to operate in accumulation mode has been developed and analyzed elaborately. The tuning range specification for the design was chosen to be 200 MHz accounting for component tolerance. Various means of measuring phase noise has been elaborately analyzed. Also detailed study on improving the noise performance of the LC-VCO has been studied.

Download or read book Design of High-Performance CMOS Voltage-Controlled Oscillators written by Liang Dai and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design of High-Performance CMOS Voltage-Controlled Oscillators presents a phase noise modeling framework for CMOS ring oscillators. The analysis considers both linear and nonlinear operation. It indicates that fast rail-to-rail switching has to be achieved to minimize phase noise. Additionally, in conventional design the flicker noise in the bias circuit can potentially dominate the phase noise at low offset frequencies. Therefore, for narrow bandwidth PLLs, noise up conversion for the bias circuits should be minimized. We define the effective Q factor (Qeff) for ring oscillators and predict its increase for CMOS processes with smaller feature sizes. Our phase noise analysis is validated via simulation and measurement results. The digital switching noise coupled through the power supply and substrate is usually the dominant source of clock jitter. Improving the supply and substrate noise immunity of a PLL is a challenging job in hostile environments such as a microprocessor chip where millions of digital gates are present.
Book Synopsis Analysis and Design of Quadrature Oscillators by : Luis B. Oliveira
Download or read book Analysis and Design of Quadrature Oscillators written by Luis B. Oliveira and published by Springer Science & Business Media. This book was released on 2008-07-08 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern RF receivers and transmitters require quadrature oscillators with accurate quadrature and low phase-noise. Existing literature is dedicated mainly to single oscillators, and is strongly biased towards LC oscillators. This book is devoted to quadrature oscillatorsand presents adetailed comparative study ofLC and RCosc- lators, both at architectural and at circuit levels. It is shown that in cross-coupled RC oscillators both the quadrature error and phase-noise are reduced, whereas in LC - cillators the coupling decreases the quadrature error, but increases the phase-noise. Thus, quadrature RC oscillators can be a practical alternative to LC oscillators, - pecially when area and cost are to be minimized. The main topics of the book are: cross-coupled LC quasi-sinusoidal oscillators, cross-coupled RC relaxation oscillators, a quadrature RC oscillator-mixer, and t- integrator oscillators. The effect of mismatches on the phase-error and the pha- noise are thoroughly investigated. The book includes many experimental results, obtained from different integrated circuit prototypes, in the GHz range. A structured design approach is followed: a technology independent study, with ideal blocks, is performed initially, and then the circuit level design is addressed. This book can be used in advanced courses on RF circuit design. In addition to post-graduate students and lecturers, this book will be of interest to design engineers and researchers in this area.

Book Synopsis Low Power VCO Design in CMOS by : Marc Tiebout
Download or read book Low Power VCO Design in CMOS written by Marc Tiebout and published by Springer Science & Business Media. This book was released on 2006-01-25 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work covers the design of CMOS fully integrated low power low phase noise voltage controlled oscillators for telecommunication or datacommuni- tion systems. The need for low power is obvious, as mobile wireless telecommunications are battery operated. As wireless telecommunication systems use oscillators in frequency synthesizers for frequency translation, the selectivity and signal to noise ratio of receivers and transmitters depend heavily on the low phase noise performance of the implemented oscillators. Datacommunication s- tems need low jitter, the time-domain equivalent of low phase noise, clocks for data detection and recovery. The power consumption is less critical. The need for multi-band and multi-mode systems pushes the high-integration of telecommunication systems. This is o?ered by sub-micron CMOS feat- ing digital ?exibility. The recent crisis in telecommunication clearly shows that mobile hand-sets became mass-market high-volume consumer products, where low-cost is of prime importance. This need for low-cost products - livens tremendously research towards CMOS alternatives for the bipolar or BiCMOS solutions in use today.

This book was released on 2015 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the analysis, design, and application of inductor-capacitor (LC) oscillators for wireless sensor networks (WSNs). First an analysis and design optimization approach for enhanced swing, low power CMOS LC oscillators is presented. A phasor based analysis is used for determining the amplitude and phase noise of these oscillators with MOSFET operation in cut-off, linear and saturation regions. The calculated steady state output amplitude and phase noise from this analysis are in agreement with Cadence Spectre simulations for different bias conditions. An application of this analysis to the design optimization of LC oscillators is also demonstrated. This is followed by a power generation method based fast start-up analysis of resonator based oscillators. A small signal two-port based approach that is design oriented is presented. The analysis has been validated with detailed circuit level simulations. Several MOSFET oscillator architectures have been analyzed and the start-up times compared using this analysis with applications to start-up time reduction of LC oscillators. A novel low voltage quadrature LC oscillator with a fast start-up is then presented. Simulations show that the proposed oscillator can obtain a phase noise of -150 dBc/Hz at 10 MHz offset for a 5 GHz center frequency and an FoM of 195 dBc/Hz. The proposed oscillator has a superior start-up performance compared to other low voltage quadrature LC oscillator architectures. The design aspect of LC oscillators focuses on a new enhanced swing class-D VCO which operates from a supply voltage as low as 300 mV. The architectural advantages are described along with an analysis for the oscillation frequency. Prototype differential and quadrature variants of the proposed VCO have been implemented in a 65 nm RF CMOS process with a 5 GHz oscillation frequency. At a 350 mV supply, the measured phase noise performance for the quadrature VCO with a 5% tuning range is -137.1 dBc/Hz at 3 MHz offset with a power dissipation of 2.1 mW from a 0.35 V supply. The highest resulting figure-of-merit (FoM) is 198.3 dBc/Hz. Finally, an application of LC oscillators for a crystal free radio-frequency (RF) receiver design has been explored. It is shown that a source-synchronous receiver with MSK modulation is a suitable choice for eliminating the crystal in WSN applications. Design trade-offs have been analyzed using system level simulations.
Book Synopsis The Design of Low Noise Oscillators by : Ali Hajimiri
Download or read book The Design of Low Noise Oscillators written by Ali Hajimiri and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is hardly a revelation to note that wireless and mobile communications have grown tremendously during the last few years. This growth has placed stringent requi- ments on channel spacing and, by implication, on the phase noise of oscillators. C- pounding the challenge has been a recent drive toward implementations of transceivers in CMOS, whose inferior 1/f noise performance has usually been thought to disqualify it from use in all but the lowest-performance oscillators. Low noise oscillators are also highly desired in the digital world, of course. The c- tinued drive toward higher clock frequencies translates into a demand for ev- decreasing jitter. Clearly, there is a need for a deep understanding of the fundamental mechanisms g- erning the process by which device, substrate, and supply noise turn into jitter and phase noise. Existing models generally offer only qualitative insights, however, and it has not always been clear why they are not quantitatively correct.
Book Synopsis LC-tank CMOS Voltage-controlled Oscillators Using High Quality Inductor Embedded in Advanced Packaging Technologies by : Sangwoong Yoon
Download or read book LC-tank CMOS Voltage-controlled Oscillators Using High Quality Inductor Embedded in Advanced Packaging Technologies written by Sangwoong Yoon and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on high-performance LC-tank CMOS VCO design at 2 GHz. The high-Q inductors are realized using wiring metal lines in advanced packages. Those inductors are used in the resonator of the VCO to achieve low phase noise, low power consumption, and a wide frequency tuning range. In this dissertation, a fine-pitch ball-grid array (FBGA) package, a multichip module (MCM)-L package, and a wafer-level package (WLP) are incorporated to realize the high-Q inductor. The Q-factors of inductors embedded in packages are compared to those of inductors monolithically integrated on Si and GaAs substrates. All the inductors are modeled with a physical, simple, equivalent two-port model for the VCO design as well as for phase noise analysis. The losses in an LC-tank are analyzed from the phase noise perspective. For the implementation of VCOs, the effects of the interconnection between the embedded inductor and the VCO circuit are investigated. The VCO using the on-chip inductors is designed as a reference. The performance of VCOs using the embedded inductor in a FBGA and a WLP is compared with that of a VCO using the on-chip inductor. The VCO design is optimized from the high-Q perspective to enhance performance. Through this optimization, less phase noise, lower power consumption, and a wider frequency tuning range are obtained simultaneously.

Available in PDF, EPUB and Kindle. Book excerpt: This volume of Analog Circuit Design concentrates on three topics: (X)DSL and other communication systems; RF MOST models; and integrated filters and oscillators. The book comprises five chapters on the first topic with six each on the other two, all written by internationally recognized experts. They are tutorial in nature and together make a substantial contribution to improving the design of analog circuits. The book is divided into three parts: Part I: (X)DSL and other Communication Systems presents some examples of recent improved modem techniques which have resulted in much higher transmission speeds over the local telephone network. It also presents components for the implementation of different standards. Part II: RF MOST Models investigates the state of the art in RF MOST models. It compares the existing BSIM3v3, Philips' Model 9 and the EKV model with respect to their capability to accurately predict GHz performance with submicron CMOST technologies. It shows how it has now become quite feasible to model a MOST at very high frequencies, giving rise to an increased use of MOST technologies in RF applications. Part III: Integrated Filters and Oscillators illustrates how the increasing use of communication tools goes hand-in-hand with the design of analog filters and oscillators with greater flexibility and higher bandwidth.
