Book A Delay locked Loop for Multiple Clock Phases delays Generation

Download or read book A Delay locked Loop for Multiple Clock Phases delays Generation written by Cheng Jia and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A Delay-Locked Loop (DLL) for the generation of multiple clock phases/delays is proposed. Several new techniques are used to help enhance the DLLs performance, specifically, to achieve wide lock range, short locking time, and reduced jitter. The DLL can be used for a variety of applications which require precise time intervals or phase shifts. The phase detector (PD), charge pump (CP), and voltage-controlled delay line (VCDL) are the three most important blocks in a DLL. In our research, we have proposed a novel structure which integrates the functionality of both the PD and CP. By using this structure, a fast switching speed can be achieved. Moreover, the combined PD and CP also lead to reduced chip area and better jitter performance. A novel phase detection algorithm is developed and implemented in the combined PD and CP structure. This algorithm also involves a start-control circuit to avoid locking failure or false lock to harmonics. With the help of this algorithm, the proposed DLL is able to achieve lock as long as the minimum VCDL delay is less than one reference clock cycle, which is the largest possible lock range that can be achieved by the DLL. The VCDL uses fully differential signaling to minimize jitter. The delay stage of the VCDL is built with a differential topology using symmetrical loads and replica-feedback biasing, which provides a low sensitivity to supply and substrate noise as well as a wide tuning range. In addition, a shift-averaging technique is used to improve the matching between delay stages and thus to equalize the delay of each individual stage.

Book Design and Analysis of Jitter tolerant Digital Delay locked Loops and Fixed Delay Lines

Download or read book Design and Analysis of Jitter tolerant Digital Delay locked Loops and Fixed Delay Lines written by James Russell Burnham and published by . This book was released on 2007 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fixed delay-line (FDL) using the same basic jitter-tolerant architecture is also presented. Two versions of the FDL, 1/4 and 1/8 cycle, are implemented in the memory interface section of a 0.13-mum CMOS digital television chip. The measured worst-case delay variation of the 1/4 cycle delay line is two delay steps, which is a factor of three lower than the simulated variation for a conventional FDL under the same conditions. Jitter-induced toggling is also reduced by more than an order of magnitude.

Book A 200 833 MHz Delay Locked Loop for DDR Memory Applications

Download or read book A 200 833 MHz Delay Locked Loop for DDR Memory Applications written by Brett Patrick Delaney and published by . This book was released on 2016 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: As memory I/O bandwidth continues to increase beyond the current multi-gigabit rates for high performance computer systems, there remains a need for a stable and robust method of clock synchronization capable of transferring data reliability between main memory and a CPU memory controller. A Delay Locked Loop (DLL) is often utilized in such a system where synchronization and removal of clock skew are necessary. Synchronization in DLL’s is carried out by continually adjusting the phase of a clock signal by adding or removing delay based on feedback provided by a Phase Detector (PD). Once phase alignment occurs, the DLL is said to be in a “Locked” state. Delay can be produced with either a VCDL (Voltage Controlled Delay Line), or a DCDL (Digitally Controlled Delay Line). Each type of delay line has their own benefits and drawbacks, many of which will be discussed throughout this paper. This thesis provides an overview of previous DLL design research, and presents a functional 45nm CMOS, 200-833 MHz delay locked loop.

Book ULTRASONIC DELAY LINE DEVELOPMENT

Download or read book ULTRASONIC DELAY LINE DEVELOPMENT written by L. LAMBERT and published by . This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress on ultrasonic delay line research is discussed. The results of a continued study of lead as a bonding and backing material for ultrasonic delay lines are presented. The tripletravel response level was reduced below the level of spurious responses due to diffraction for a majority of delay line applications. The results of an investigation of the diffraction field, in a solid medium, of an ultrasonic transducer are presented. The experimental results indicated that the assumptions made in the mathematical description of acoustic diffraction phenomena are valid. Design techniques for polygonal delay lines are discussed in terms of spurious response levels. A theoretical analysis, based on Fresnel diffraction theory, is presented, which results in the determination of the optimum transducer length for minimum spurious response level. (Author).
