Download Analysis and Design of High-speed CMOS Frequency Dividers Book in PDF, Epub and Kindle
A frequency divider is one of the most fundamental and challenging blocks used in high-speed communication systems. Three high-speed dividers with different topologies, LC-tank frequency divider, CML ring frequency divider, and CML DFF frequency divider with negative feedback, are analyzed based on the locking phenomena. The locking to the injected signal happens as long as the frequency and the amplitude of the injected signal are in the desired operation region of the divider's sensitivity curve. A phase shift (which is a function of both frequency and the amplitude of the injected signal) occurs in the circuit and the divider will be locked to the injected frequency. Locking to an external signal may not necessarily occur just by considering the frequency of the injection signal being in the locking range, even if the frequency of the injection signal is very close to the self-oscillation frequency in a wide locking range scenario without the proper injected signal amplitude. To measure the phase shift when the oscillator is locked to the injected frequency, a novel procedure is developed. This procedure gives us a very precise tool to measure the locking phase, instantaneous phase, or the phase between any two signals inside the topology loop and provides a good ability for better understanding of the injection locking concept and the behavior of the divider in the presence of an injected signal. The simulations are using transistor models from TSMC 65nm CMOS process.

Download CMOS PLL Synthesizers: Analysis and Design Book in PDF, Epub and Kindle
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.

Download Design of a CMOS VCO and Frequency Divider for 5 GHz Applications Book in PDF, Epub and Kindle
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.

Download High Speed CMOS Design Styles Book in PDF, Epub and Kindle
High Speed CMOS Design Styles is written for the graduate-level student or practicing engineer who is primarily interested in circuit design. It is intended to provide practical reference, or `horse-sense', to mechanisms typically described with a more academic slant. This book is organized so that it can be used as a textbook or as a reference book. High Speed CMOS Design Styles provides a survey of design styles in use in industry, specifically in the high speed microprocessor design community. Logic circuit structures, I/O and interface, clocking, and timing schemes are reviewed and described. Characteristics, sensitivities and idiosyncrasies of each are highlighted. High Speed CMOS Design Styles also pulls together and explains contributors to performance variability that are associated with process, applications conditions and design. Rules of thumb and practical references are offered. Each of the general circuit families is then analyzed for its sensitivity and response to this variability. High Speed CMOS Design Styles is an excellent source of ideas and a compilation of observations that highlight how different approaches trade off critical parameters in design and process space.
