Book Synopsis High-Speed and High-Performance Direct Digital Frequency Synthesizer Design by : Jun-an Zhang
Download or read book High-Speed and High-Performance Direct Digital Frequency Synthesizer Design written by Jun-an Zhang. This book was released on 2022-03-22. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on design technology of high-speed and high-performance direct digital frequency synthesizer (DDS) chip. The technologies involves phase to amplitude converter design, D/A converter design, phase accumulator design, multi-chip synchronization circuit design, etc. In each chapter, the concept of the technology is explained first, and then the features of different implementation schemes are introduced through the real design cases. More over, a design case of a 2.5GHz monolithic DDS in 0.18 μm CMOS which was designed by the authors are introduced in detail, which can help the reader understanding about the of DDS design deeply. The book is suitable for the readers who are interested to learn practical design technology in DDS. The book can benefit researchers, engineers, and graduate students in fields of mix-signal IC design, communication engineering, electronics engineering, and radar engineering, etc.

Book Synopsis Direct Digital Frequency Synthesizer Implementation Using a High Speed ROM Alternative in IBM 0.13u Technology by : Matthew R. Gerald
Download or read book Direct Digital Frequency Synthesizer Implementation Using a High Speed ROM Alternative in IBM 0.13u Technology written by Matthew R. Gerald. This book was released on 2006. Available in PDF, EPUB and Kindle. Book excerpt: The direct digital synthesizer is a method of signal generation with many benefits. DDS designs are able to switch frequencies very quickly and also tune precisely to many different frequencies with the use of a constant operating frequency. There is a need for a low power, high speed DDS in the form an ASIC design. One major bottleneck in common DDS systems is the slow access time of a ROM. There is also a need for a high speed ROM alternative. This thesis delivers a high speed ASIC Direct Digital Synthesizer which operates at a 1 GHz operating frequency. This high speed DDS design also operated with the low power consumption of fewer than 60 mW. As the results indicate this thesis delivers a possible solution to all of the stated design needs. This implementation could be used by any design that requires an ASIC generated sine wave as an input. This design also implements a unique alternative to the well known ROM bottleneck. This alternative performed at a high operating frequency and also allows for the addition of a pipeline stage, if an even higher operating frequency was desired. Any ASIC design that requires fast frequency hopping could utilize this implementation as well. This design was able to switch frequencies in fewer than 6 ns at the 1 GHz operating frequency. The frequencies this design was able to output ranged between 976.563 kHz and 249.023 MHz.

Book Synopsis Direct Digital Frequency Synthesizers by : Venceslav F. Kroupa
Download or read book Direct Digital Frequency Synthesizers written by Venceslav F. Kroupa. This book was released on 1998-11-18. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of integrated circuits (IC), digital systems havebecome widely used in modern electronic devices, includingcommunications and measurement equipment. Direct Digital FrequencySynthesizers (DDS) are used in communications as transmitterexciters and local oscillators in receivers. The advantages aresuperior frequency stability, the same as that of the driving clockoscillator, and short switching times. The difficulties are loweroutput frequencies and rather large spurious signals. Compiled for practicing engineers who do not have theprerequisite of a specialist's knowledge in Direct DigitalFrequency Synthesizers (DDS), this collection of 40 importantreprinted papers and 9 never-before published contributionspresents a comprehensive introduction to DDS properties and a clearunderstanding of actual devices. The information in this volume canlead to easier computer simulations and improved designs. Featured topics include: * Discussion of principles and state of the art of wide-rangeDDS * Investigation of spurious signals in DDS * Combination of DDS with Phase Lock Loops (PLL) * Examination of phase and background 'noise' in DDS * Introduction to Digital to Analog Conversion (DAC) * Analysis of mathematics of quasiperiodic omission ofpulses DDFS can also serve as a textbook for students seeking essentialbackground theory.
