As electronics continue to become faster, smaller and more efficient, development and research around clocking signals and circuits has accelerated to keep pace. This book bridges the gap between the classical theory of clocking circuits and recent technological advances, making it a useful guide for newcomers to the field, and offering an opportunity for established researchers to broaden and update their knowledge of current trends.

Featuring an extensive 40 page tutorial introduction, this carefully compiled anthology of 65 of the most important papers on phase-locked loops and clock recovery circuits brings you comprehensive coverage of the field-all in one self-contained volume. You'll gain an understanding of the analysis, design, simulation, and implementation of phase-locked loops and clock recovery circuits in CMOS and bipolar technologies along with valuable insights into the issues and trade-offs associated with phase locked systems for high speed, low power, and low noise.

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 examines the issue of design of fully integrated frequency synthesizers suitable for system-on-a-chip (SOC) processors. This book takes a more global design perspective in jointly examining the design space at the circuit level as well as at the architectural level. The coverage of the book is comprehensive and includes summary chapters on circuit theory as well as feedback control theory relevant to the operation of phase locked loops (PLLs). On the circuit level, the discussion includes low-voltage analog design in deep submicron digital CMOS processes, effects of supply noise, substrate noise, as well device noise. On the architectural level, the discussion includes PLL analysis using continuous-time as well as discre- time models, linear and nonlinear effects of PLL performance, and detailed analysis of locking behavior. The material then develops into detailed circuit and architectural analysis of specific clock generation blocks. This includes circuits and architectures of PLLs with high power supply noise immunity and digital PLL architectures where the loop filter is digitized. Methods of generating low-spurious sampling clocks for discrete-time analog blocks are then examined. This includes sigma-delta fractional-N PLLs, Direct Digital Synthesis (DDS) techniques and non-conventional uses of PLLs. Design for test (DFT) issues as they arise in PLLs are then discussed. This includes methods of accurately measuring jitter and built-in-self-test (BIST) techniques for PLLs.

This thesis covers the analysis, design and simulation of a low-power low-noise CMOS Phase-Locked Loop (PLL). Starting with the PLL basics, this thesis discussed the PLL loop dynamics and behavioral modeling. In this thesis, the detailed design and implementation of individual building blocks of the low-power low-noise PLL have been presented. In order to improve the PLL performance, several novel architectural solutions has been proposed. To reduce the effect of blind-zone and extend the detection range of Phase Frequency Detector (PFD), we proposed the Delayed-Input-Edge PFD (DIE-PFD) and the Delayed-Input-Pulse PFD (DIP-PFD) with improved performance. We also proposed a NMOS-switch high-swing cascode charge pump that significantly reduces the output current mismatches. Voltage Controlled Oscillator (VCO) consumes the most power and dominates the noise in the PLL. A differential ring VCO with 550MHz to 950MHz tuning range has been designed, with the power consumption of the VCO is 2.5mW and the phase noise -105.2dBc/Hz at 1MHz frequency offset. Finally, the entire PLL system has been simulated to observe the overall performance. With input reference clock frequency equal 50MHz, the PLL is able to produce an 800MHz output frequency with locking time 400ns. The power consumption of the PLL system is 2.6mW and the phase noise at 1MHz frequency offset is -119dBc/Hz. The designs are implemented using IBM 0.13æm CMOS technology.

After a review of PLL essentials, this uniquely comprehensive workbench guide takes you step-by-step through operation principles, design procedures, phase noise analysis, layout considerations, and CMOS realizations for each PLL building block. You get full details on LC tank oscillators including modeling and optimization techniques, followed by design options for CMOS frequency dividers covering flip-flop implementation, the divider by 2 component, and other key factors. The book includes design alternatives for phase detectors that feature methods to minimize jitter caused by the dead zone effect. You also find a sample design of a fully integrated PLL for WLAN applications that demonstrates every step and detail right down to the circuit schematics and layout diagrams. Supported by over 150 diagrams and photos, this one-stop toolkit helps you produce superior PLL designs faster, and deliver more effective solutions for low-cost integrated circuits in all RF applications.
