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 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.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Presented in this work is a novel design technique for a low-phase-noise high-frequency CMOS voltage-controlled oscillator. Phase noise is generated from electrical noise near DC, the oscillation frequency, and its harmonics. In CMOS technology, low-frequency flicker noise dominates the close-in phase noise of the VCO. The proposed technique minimizes the VCO phase noise by seeking to eliminate the effect of flicker noise on the phase n6se. This is accomplished by canceling out the DC component of the impulse sensitivity function (ISF) corresponding to each flicker-noise source, thus preventing the up-conversion of low-frequency noise into phase noise. The proposed circuit topology is a modified version of the complementary cross-coupled transconductance VCO, where additional feedback paths are introduced such that a designer can choose the feedback ratios, transistor sizes, and bias voltages to achieve the previously mentioned design objectives. A step-by-step design algorithm is presented along with a MATLAB script to aid in the computation of the ISFs and the phase noise of the VCO. Using this algorithm, a 5-GHz VCO was designed and fabricated in a 0.18m︡ CMOS process, and then tested for comparison with simulated results.

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: Two kinds of voltage-controlled oscillators (VCO)--active inductor based VCO and LC cross-coupled VCO--are studied in this work. Although the phase noise performance is not competitive, the proposed active inductor based VCO provide an alternative method to VCO design with very small chip area and large tuning range. The measurement shows a test oscillator based on active inductor topology successfully oscillates near 530MHz band. The phase noise of the widely used LC cross-coupled VCO is extensively investigated in this work. Under the widely used power dissipation and chip area constraints, a novel optimization procedure in LC oscillator design centered on a new inductance selection criterion is proposed. This optimization procedure is based on a physical phase noise model. From it, several closed-form expressions are derived to describe the phase noise generated in the LC oscillators, which indicate that the phase noise is proportional to the L2· gL3 factor. The minimum value of this factor for an area-limited spiral inductor is proven to monotonically decrease with increasing inductance, suggesting a larger inductance is helpful to reduce the phase noise in LC VCO design. The validity of the optimization procedure is proven by simulations. Two test chips are designed and measured.

This book was released on 2013-06-29 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent boom in the mobile telecommunication market has trapped the interest of almost all electronic and communication companies worldwide. New applications arise every day, more and more countries are covered by digital cellular systems and the competition between the several providers has caused prices to drop rapidly. The creation of this essentially new market would not have been possible without the ap pearance of smalI, low-power, high-performant and certainly low-cost mobile termi nals. The evolution in microelectronics has played a dominant role in this by creating digital signal processing (DSP) chips with more and more computing power and com bining the discrete components of the RF front-end on a few ICs. This work is situated in this last area, i. e. the study of the full integration of the RF transceiver on a single die. Furthermore, in order to be compatible with the digital processing technology, a standard CMOS process without tuning, trimming or post-processing steps must be used. This should flatten the road towards the ultimate goal: the single chip mobile phone. The local oscillator (LO) frequency synthesizer poses some major problems for integration and is the subject of this work. The first, and also the largest, part of this text discusses the design of the Voltage Controlled Oscillator (VCO). The general phase noise theory of LC-oscillators is pre sented, and the concept of effective resistance and capacitance is introduced to char acterize and compare the performance of different LC-tanks.

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.

This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Voltage controlled oscillators (VCOs) are key components in frequency synthesizers for Radio Frequency (RF) wireless communications. The design of monolithic VCOs with standard CMOS processes has been the object of several recent research projects. The common goal of these attempts has been to investigate the possibility of meeting the very demanding VCO phase noise specifications without making use of bipolar processes or external components. Two categories of VCOs are studied in this thesis, one involving an inductor, and the other is inductor free, which is a ring oscillator. The study of the phase noise performance of complementary LC VCO shows that most of the phase noises come from the tail current. A modification has been made based on this topology, where the tail transistor is removed. However this brings another problem: higher power consumption. To overcome this problem, sub-threshold techniques have been used leading to sub-threshold LC VCO. A Ring oscillator is designed at the end because of its wide tuning range and ease of implementation. Schematic simulations, layout and post-layout simulations are accomplished using TSMC 0.18 um CMOS technology. The performances of the three types of VCOs are compared regarding the oscillating frequency, phase noise and tuning range. All of these can be used in the Bluetooth applications. In addition, the figure of merit (FOM) of the designed VCOs is compared with work by other researchers.
