Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the design of a new CMOS Voltage Controlled Oscillator and a frequency divider, both of which form important blocks in the design of a PLL synthesizer. These components are important because they operate at the highest frequencies within the PLL and also consume most of the power as compared to the other components. Both these circuits have been an active topic of research in recent years especially with the scaling of technology bringing hopes of complete system-on-chip (SOC) integration at RF frequencies. The circuits in this thesis are designed for 5 GHz applications, mainly for the IEEE Wireless Local Area Network (WLAN) 802.11a standard which spans the frequency range from 5.14 GHz to 5.72 GHz. The first part of the thesis is an introduction to receiver architectures, VCO's and frequency dividers in general. The second part deals with the design, analysis and simulation results of a novel VCO presented in this work. The VCO achieves a tuning range of 130 MHz around a center frequency of 5.70 GHz and a low phase noise of -114 dBc/Hz at an offset of 1 MHz. The third part presents the design approach adopted here to designing a high frequency divider using dynamic logic and its simulation results. The logic used here is True Single Phase Clocking (TSPC), which makes use of a single clock thereby avoiding the problems of clock skew and loading. Two main blocks have been presented, the divide-by-2 and divide-by-2/3. These blocks are then cascaded to achieve higher division ratios.

This book was released on 2011-10-18 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low Power Consumption is one of the critical issues in the performance of small battery-powered handheld devices. Mobile terminals feature an ever increasing number of wireless communication alternatives including GPS, Bluetooth, GSM, 3G, WiFi or DVB-H. Considering that the total power available for each terminal is limited by the relatively slow increase in battery performance expected in the near future, the need for efficient circuits is now critical. This book presents the basic techniques available to design low power RF CMOS analogue circuits. It gives circuit designers a complete guide of alternatives to optimize power consumption and explains the application of these rules in the most common RF building blocks: LNA, mixers and PLLs. It is set out using practical examples and offers a unique perspective as it targets designers working within the standard CMOS process and all the limitations inherent in these technologies.

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 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.

Download or read book Design of High speed Communication Circuits written by Ramesh Harjani and published by World Scientific. This book was released on 2006 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: MOS technology has rapidly become the de facto standard for mixed-signal integrated circuit design due to the high levels of integration possible as device geometries shrink to nanometer scales. The reduction in feature size means that the number of transistor and clock speeds have increased significantly. In fact, current day microprocessors contain hundreds of millions of transistors operating at multiple gigahertz. Furthermore, this reduction in feature size also has a significant impact on mixed-signal circuits. Due to the higher levels of integration, the majority of ASICs possesses some analog components. It has now become nearly mandatory to integrate both analog and digital circuits on the same substrate due to cost and power constraints. This book presents some of the newer problems and opportunities offered by the small device geometries and the high levels of integration that is now possible. The aim of this book is to summarize some of the most critical aspects of high-speed analog/RF communications circuits. Attention is focused on the impact of scaling, substrate noise, data converters, RF and wireless communication circuits and wireline communication circuits, including high-speed I/O.

This book was released on 2007-05-08 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past 10 years extensive effort has been dedicated to commercial wireless local area network (WLAN) systems. Despite all these efforts, however, none of the existing systems has been successful, mainly due to their low data rates. The increasing demand for WLAN systems that can support data rates in excess of 20 Mb/s enticed the FCC to create an unlicensed national information infrastructure (U–NII) band at 5 GHz. This frequency band provides 300 MHz of spectrum in two segments: a 200 MHz(5.15–5.35 GHz) and a 100 MHz (5.725–5.825 GHz) frequency band. This newly released spectrum, and the fast trend of CMOS scaling, provide an opportunity to design WLAN systems with high data rate and low cost. One of the existing standards at 5 GHz is the European high performance radio LAN (HIPERLAN) standard that supports data rates as high as 20 Mb/s. One of the main building blocks of each wireless system is the f- quency synthesizer. Phase–locked loops (PLLs) are universally used to design radio frequency synthesizers. Reducing the power consumption of the frequency dividers of a PLL has always been a challenge. In this book, we introduce an alternative solution for conventional flipflop based xiv MULTI–GHZ FREQUENCY SYNTHESIS & DIVISION frequency dividers. An injection–locked frequency divider (ILFD) takes advantage of the narrowband nature of the wireless systems and employs resonators to trade off bandwidth for power.
