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.

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.

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.

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.

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.
