Book Description
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.
Design of Fractional-N Phase Locked Loops for Frequency Synthesis from 30 to 40 GHz

Book Description
"High-frequency fractional-N PLLs in CMOS technology in the 30 to 40 GHz are very dicult to design when considering power, area, phase noise requirements and frequency range of operation. One of the diculties is to synthesize the loop lter of the PLL such that it meets the phase noise characteristics using the information available for all the components that make up the PLL. At the same time, predicting the phase noise output of the PLL using extracted layout results takes a long time to simulate and often the solution does not converge, thereby lengthening the design cycle. This thesis proposes a new methodology for designing high performance wide-band fractional-N PLLs in the 30-40 GHz range. The method begins by rst designing the phase-frequency detector/charge-pump, voltage-controlled oscillator and frequency divider circuit for realization in a specic CMOS technology. The method of choice mixes insight deemed from both a theoretical and simulation perspective. Next, the loop lter is derived based on the layout extracted behaviour of each component. Once complete, all components of the PLL are described using the high-level description language of Verilog-A available in the Cadence tool set over its full range of operating characteristics. Ideally, these components would be fabricated rst and characterized afterward. The Verilog-A description of the PLL enables a fast and ecient simulation of the complete PLL in a closed-loop conguration. This latter steps allows further optimization of the overall design. Two chips have been fabricated; one in a 0.13 m CMOS process from IBM and another in a 65 nm CMOS process from TSMC. One chip contain the design of a 28 GHz VCO and another containing the design of a programmable frequency divider circuit. Experimental results for both chip are provided." --

Characterization and Implementation of an Injection Locked Frequency Divider Based on Relaxation Oscillator

Book Description
There has been a dramatic increase in wireless awareness among the user community in the past few years. As the wireless communication devices require more integration in terms of both hardware and software, the low-power integrated circuit (IC) solution has gained higher dedication and will dominate in the future radio-frequency IC (RFIC) design. Complementary Metal-Oxide Semiconductor (CMOS) process is extremely attractive for such applications because of its low cost and the possibility to integrate baseband and high frequency circuits on the same chip. The transceiver is often the most power-hungry block in a wireless communication system. The frequency divider (prescaler) and the voltage controlled oscillator (VCO) which are essential building blocks of in the frequency synthesizer of the transmitter are among the major sources of power consumption. This work focuses on prescalers. The injection-locked frequency dividers (ILFD) were introduced in the recent past for low-power frequency division. ILFDs can consume an order of magnitude lower power when compared to conventional flip-flop based dividers. However their range of operating frequency, also known as the locking range, is limited. ILFDs can be classified as LC tank, ring or relaxation oscillator based. There have been a lot of published works on the LC tank and ring oscillator based ILFDs. However, the one on relaxation oscillator based ILFD has been rarely reported, especially for RF applications. Besides, it is usually employed to implement a single division ratio such as 2, 3, 4 with an ILFD, while dual- or multi-moduli prescaler is more attractive to an RF synthesizer and are also rarely studied among published ILFDs. The goal of this work is to initially characterize the relaxation ILFD for RF applications. The locking range is optimized by the proposed topology. Besides, mathematical derivation is developed to verify the optimization. ILFD is also designed for different moduli with an easily controlled manner. Finally, the dual-modulus ILFD is also implemented based on the proposed structure. A prototype is fabricated in a 90-nm CMOS process and successfully tested.

All-Digital Frequency Synthesizer in Deep-Submicron CMOS

Category : Technology & Engineering
Languages : en
Pages : 281
Book Description
A new and innovative paradigm for RF frequency synthesis and wireless transmitter design Learn the techniques for designing and implementing an all-digital RF frequency synthesizer. In contrast to traditional RF techniques, this innovative book sets forth digitally intensive design techniques that lead the way to the development of low-cost, low-power, and highly integrated circuits for RF functions in deep submicron CMOS processes. Furthermore, the authors demonstrate how the architecture enables readers to integrate an RF front-end with the digital back-end onto a single silicon die using standard ASIC design flow. Taking a bottom-up approach that progressively builds skills and knowledge, the book begins with an introduction to basic concepts of frequency synthesis and then guides the reader through an all-digital RF frequency synthesizer design: Chapter 2 presents a digitally controlled oscillator (DCO), which is the foundation of a novel architecture, and introduces a time-domain model used for analysis and VHDL simulation Chapter 3 adds a hierarchical layer of arithmetic abstraction to the DCO that makes it easier to operate algorithmically Chapter 4 builds a phase correction mechanism around the DCO such that the system's frequency drift or wander performance matches that of the stable external frequency reference Chapter 5 presents an application of the all-digital RF synthesizer Chapter 6 describes the behavioral modeling and simulation methodology used in design The final chapter presents the implementation of a full transmitter and experimental results. The novel ideas presented here have been implemented and proven in two high-volume, commercial single-chip radios developed at Texas Instruments: Bluetooth and GSM. While the focus of the book is on RF frequency synthesizer design, the techniques can be applied to the design of other digitally assisted analog circuits as well. This book is a must-read for students and engineers who want to learn a new paradigm for RF frequency synthesis and wireless transmitter design using digitally intensive design techniques.
