This book was released on 1969 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of multistable elements for sequential counting time interval measurement is promising if sampling errors can be reduced. A significant improvement in accuracy can be obtained by using a scale-time conversion of the interval between the start and first digitizing impulse and the interval between the last digitizing impulse and the stop impulse. Thus, no reduction in impulse period and no increase in counter stop requirement is needed.

Download or read book CMOS Time Mode Circuits and Systems written by Fei Yuan and published by CRC Press. This book was released on 2018-09-03 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time-mode circuits, where information is represented by time difference between digital events, offer a viable and technology-friendly means to realize mixed-mode circuits and systems in nanometer complementary metal-oxide semiconductor (CMOS) technologies. Various architectures of time-based signal processing and design techniques of CMOS time-mode circuits have emerged; however, an in-depth examination of the principles of time-based signal processing and design techniques of time-mode circuits has not been available—until now. CMOS Time-Mode Circuits and Systems: Fundamentals and Applications is the first book to deliver a comprehensive treatment of CMOS time-mode circuits and systems. Featuring contributions from leading experts, this authoritative text contains a rich collection of literature on time-mode circuits and systems. The book begins by presenting a critical comparison of voltage-mode, current-mode, and time-mode signaling for mixed-mode signal processing and then: Covers the fundamentals of time-mode signal processing, such as voltage-to-time converters, all-digital phase-locked loops, and frequency synthesizers Investigates the performance characteristics, architecture, design techniques, and implementation of time-to-digital converters Discusses time-mode delta-sigma-based analog-to-digital converters, placing a great emphasis on time-mode quantizers Includes a detailed study of ultra-low-power integrated time-mode temperature measurement systems CMOS Time-Mode Circuits and Systems: Fundamentals and Applications provides a valuable reference for circuit design engineers, hardware system engineers, graduate students, and others seeking to master this fast-evolving field.

Download or read book An Assessment of Precision Time and Time Interval Science and Technology written by National Research Council and published by National Academies Press. This book was released on 2002-11-04 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of time is essential to precise knowledge of location, and for this reason the Navy, with its need to navigate on the high seas, has historically played an important role in the development and application of advanced time realization and dissemination technologies. Discoveries coming from basic research funded by the Office of Naval Research (ONR) lie at the heart of today's highest performance atomic clocks, Naval Research Laboratory (NRL) expertise played a role in developing the space-qualified atomic clocks that enable the Global Positioning System (GPS), and the U.S. Naval Observatory (USNO) maintains and disseminates the standard of time for all of the Department of Defense (DOD). The Navy has made major investments in most aspects of precision time and time interval (PTTI) science and technology, although specific PTTI-related research has also been funded by the Defense Advanced Research Projects Agency (DARPA) and non-DOD agencies such as the National Science Foundation (NSF), the National Aeronautics and Space Administration (NASA), and the Department of Commerce. Navy funding, largely through ONR, has a history of being an early enabler of key new developments. Judicious funding decisions by the Navy-particularly by ONR program officers-have underpinned most of the major advances in PTTI science and technology (S&T) in the last 50 years. PTTI is important to modern naval needs, and indeed to all the armed Services, for use in both navigation and communications. Precise time synchronization is needed to efficiently determine the start of a code sequence in secure communications, to perform navigation, and to locate the position of signal emitters. Precise frequency control is required in communications for spectrum utilization and frequency-hopped spread-spectrum techniques. There are many examples of essential military operations that depend on PTTI and could benefit from improvements in PTTI technology. These include: -GPS clocks and autonomous operations, -Weapon system four-dimensional coordination, -GPS antijamming, -Network-centric warfare, and -Secure military communications. This report summarizes that reductions in the size, weight, and power requirements and increases in the ruggedness of PTTI devices without sacrificing performance would put more accurate and precise timekeeping in the hands of the warrior, improving capabilities in all of the above operations.
Download or read book A PC Based Time Interval Counter With 200 PS Resolution written by and published by . This book was released on 2004 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the design and technical features of the precise time-interval counters realized as PC computer boards with ISA, PCI, and PXI interfaces. Thanks to the use of a specialized, interpolating counter chip fabricated in CMOS FPGA technology, the 200 ps resolution (1 LSB - Least Significant Bit) was achieved in single-shot measurements of time intervals within the range from 0 to 43 s. The standard measurement uncertainty is below 1 LSB as a result of automatic correction of nonlinearity of two interpolators contained in the FPGA counter chip. The counter board can also be used for frequency measurement up to 1.1 GHz. The dedicated software operating in a Windows environment provides comprehensive control, diagnostics, and statistical processing of the measured data.
