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.

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.

This book was released on 2006-07-18 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: try to predict it using mathematical expressions. His heuristic model without mathematical proof is almost universally accepted. However, it entails a c- cuit specific noise factor that is not known a priori and so is not predictive. In this work, we attempt to address the topic of oscillator design from a diff- ent perspective. By introducing a new paradigm that accurately captures the subtleties of phase noise we try to answer the question: 'why do oscillators behave in a particular way?' and 'what can be done to build an optimum design?' It is also hoped that the paradigm is useful in other areas of circuit design such as frequency synthesis and clock recovery. In Chapter 1, a general introduction and motivation to the subject is presented. Chapter 2 summarizes the fundamentals of phase noise and timing jitter and discusses earlier works on oscillator's phase noise analysis. Chapter 3 and Chapter 4 analyze the physical mechanisms behind phase noise generation in current-biased and Colpitts oscillators. Chapter 5 discusses design trade-offs and new techniques in LC oscillator design that allows optimal design. Chapter 6 and Chapter 7 discuss a topic that is typically ignored in oscillator design. That is flicker noise in LC oscillators. Finally, Chapter 8 is dedicated to the complete analysis of the role of varactors both in tuning and AM-FM noise conversion.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces low-noise and low-power design techniques for phase-locked loops and their building blocks. It summarizes the noise reduction techniques for fractional-N PLL design and introduces a novel capacitive-quadrature coupling technique for multi-phase signal generation. The capacitive-coupling technique has been validated through silicon implementation and can provide low phase-noise and accurate I-Q phase matching, with low power consumption from a super low supply voltage. Readers will be enabled to pick one of the most suitable QVCO circuit structures for their own designs, without additional effort to look for the optimal circuit structure and device parameters.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing demand for operating bandwidth in modern communication and sensing systems coupled with the shift in cellular networks towards mm-Wave 5G and beyond have demanded a need for voltage-controlled oscillators (VCOs) that can simultaneously achieve wide tuning range (TR) and low phase noise (PN). This demand has created a trend in research that explores new techniques for extending VCO tuning range while not sacrificing PN performance. However, challenges exist for designing mm wave VCOs, such as the low-quality factor associated with passive elements and the significant impact of routing parasitics. These challenges bring about a need to innovate the VCO design methodology.
