This book was released on 2017 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project focuses on the design and simulation of a digitally-controlled oscillator (DCO) for an all-digital phase-locked loop in a 180nm CMOS process. A ring oscillator with cross-coupled inverter-based delay cells was employed to reduce jitter. The cross-coupled inverters reduce jitter by keeping edge rates high by means of positive feedback. A binarily-weighted capacitive load DAC was used at the output of each delay cell to adjust the frequency of oscillation. Large device sizes were required in the delay cells because each delay cell drives a large capacitive load of 256 unit capacitors and switches in the capacitive load DAC. In addition, the outer pair of inverters used in each delay cell have to be large enough to be able to overcome the previous logic state held by the internal pair of cross-coupled inverters. A wide frequency range with low jitter was successfully achieved.

This book was released on 2017 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: A phase-locked loop (PLL) is widely used on many integrated circuits to provide an accurate and stable clock. A PLL uses negative feedback around an on-chip oscillator that the feedback loop constantly adjusts to match the phase and frequency of an input reference clock. This project focused on the design of a crystal oscillator in 0.18 um CMOS, which is used to provide an accurate reference clock for an all digital phase-locked loop. This design makes use of an on-chip oscillator which utilizes an external off-chip crystal to provide a highly accurate frequency. The crystal oscillator circuit was designed using Cadence Virtuoso computer-aided design (CAD) software, and verified using the Spectre circuit simulator across different process, supply voltage, and temperature (PVT) variations.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Download or read book A New Programmable Low Noise All Digital Phase locked Loop Architecture written by Justin L. Gaither and published by . This book was released on 2005 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the electronics industry today almost without exception there are phase-locked loops (PLL) implemented within each system and often within each integrated circuit (IC). In fact, most PLL's are implemented monolithically within ICs without any or with very few external components. Additionally, most are implemented as Analog PLL's utilizing only a digital phase detector. This is also evident in the majority of recent publications which focus on PLL structures with on-chip voltage controlled oscillators using charge pumps and ring or LC oscillators. However, the problem with most on-chip VCO's is that they are far noisier than the external crystal types. The noise in the integrated oscillators forces designers to use larger loop bandwidths than would be required with less noisy VCO's; subsequently they have poor noise filtering capabilities. Additionally, analog PLL's are usually fixed in nature. Loop components such as charge-pumps and loop filters are implemented as analog components with little or no flexibility. The focus of this thesis is the design and implementation of a very low cost, low noise Programmable All Digital PLL (ADPLL) which utilizes a low cost digital to analog converter (DAC), a voltage controlled crystal oscillator (VCXO), and a field programmable gate array (FPGA). The use of FPGA technology for digital design implementation is universal in the industry and provides benefits far beyond the implementation of ADPLL's. In fact, in almost every system today, an FPGA already exists. Therefore, the inclusion of a DPLL within existing system components would be at little or no cost. The implementation of the PLL digitally not only allows us to implement it within an FPGA, but also allows us to adapt and configure the PLL for many applications and tune it for best performance. Digital circuits also have increased noise margin and are not affected by the same noise issues associated with Analog PLL's such as temperature, voltage and noise coupled from other signals or circuits. The DPLL developed is flexible and can be configured to operate as a clock and data recovery circuit (CDR), clock multiplier, clock synthesizer, or noise filtering PLL. Using an external VCXO provides a very low noise basis for the PLL and such that we can implement very low bandwidths without sacrificing the quality of its output. In this thesis we will present the theory, architecture, design, hardware and implementation of the ADPLL in addition to the results of the testing of the prototype ADPLL that was built.
