Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the architecture and implementation of a novel 10-bit hybrid Analog to Digital Converter using Flash and Delay Line concepts. Flash ADCs employ power hungry comparators which increase the overall power consumption of a high resolution ADC. High resolution flash also requires precision analog circuit design. Delay line ADCs are based on digital circuits and operate at low power. Both Flash based ADCs and delay line based ADCs can be used to get a fast analog to digital conversion, but with limited resolution. These two approaches are combined to achieve a 10-bit resolution (4 bits using Flash and 6 bits using delay line) without compromising on speed and maintaining low power operation. Low resolution of Flash also helps in reducing the analog circuit design complexity of the voltage comparators. The ADC was capable of running at 100M samples/s, with an ENOB of 8.82 bits, consuming 8.59mW at 1.8V.

Available in PDF, EPUB and Kindle. Book excerpt: Delay line ADCs become more and more attractive with technology scaling to smaller dimensions with lower voltages. Time domain resolution can be increased by high speed delay cells. A GHz sampling rate can be easily achieved with low power. However, linearity, which has always been an issue, becomes a problem with longer delay lines. Resolutions of reported delay-line ADCs are hardly more than 4 bits with sampling rates of hundreds of MHz. Thus, this dissertation addresses the linearity issue of delay line ADCs. First, a novel 11-bit hybrid ADC using flash and delay line architectures, where a 4-bit flash ADC is followed by a 7-bit delay-line ADC, is proposed. In this structure, the noise/error of the second stage delay-line ADC is attenuated at the hybrid ADC output, such that the overall performance would not be limited by the poor linearity of the delay-line ADC. The achieved figure of merit (FOM) of 33.8 fJ/conversion-step is competitive with state-of-the-art ADCs. Furthermore, the proposed ADC inherits accuracy and high speed from the flash ADC and the delay-line ADC, respectively. The inherited advantages strongly support the scalability of the proposed ADC to provide a better performance with low power in further scaled fabrication processes. Second, in order to remove the harmonic distortion of delay-line ADC, we present a technique which extends harmonic distortion correction (HDC) to digitally calibrate a delay-line ADC. In our simulation results, digital calibration improves SNDR from 25.6 dB to 42.5 dB by averaging $2^{27}$ sample points, which corresponds to a 0.86 second calibration time. Last, a multiple-pass delay line ADC is proposed to improve overall ADC performance in terms of speed and resolution. In this structure, a multiple-pass delay cell can be early triggered by the previous cell to increase speed. Also, phase interpolation is used to improve the effective number of bits. The design is designed and simulated in a commercial 40nm process technology. With 500MHz sampling rate, the multiple-pass delay line ADC achieves an SNDR of 37 dB and consumes 4.2 mW, which is competitive with other reported ADCs.

Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the engineering principles of embedded systems, with a focus on modeling, design, and analysis of cyber-physical systems. The most visible use of computers and software is processing information for human consumption. The vast majority of computers in use, however, are much less visible. They run the engine, brakes, seatbelts, airbag, and audio system in your car. They digitally encode your voice and construct a radio signal to send it from your cell phone to a base station. They command robots on a factory floor, power generation in a power plant, processes in a chemical plant, and traffic lights in a city. These less visible computers are called embedded systems, and the software they run is called embedded software. The principal challenges in designing and analyzing embedded systems stem from their interaction with physical processes. This book takes a cyber-physical approach to embedded systems, introducing the engineering concepts underlying embedded systems as a technology and as a subject of study. The focus is on modeling, design, and analysis of cyber-physical systems, which integrate computation, networking, and physical processes. The second edition offers two new chapters, several new exercises, and other improvements. The book can be used as a textbook at the advanced undergraduate or introductory graduate level and as a professional reference for practicing engineers and computer scientists. Readers should have some familiarity with machine structures, computer programming, basic discrete mathematics and algorithms, and signals and systems.

Book excerpt: Time-interleaved Analog-to-Digital Converters describes the research performed on low-power time-interleaved ADCs. A detailed theoretical analysis is made of the time-interleaved Track & Hold, since it must be capable of handling signals in the GHz range with little distortion, and minimal power consumption. Timing calibration is not attractive, therefore design techniques are presented which do not require timing calibration. The design of power efficient sub-ADCs is addressed with a theoretical analysis of a successive approximation converter and a pipeline converter. It turns out that the first can consume about 10 times less power than the latter, and this conclusion is supported by literature. Time-interleaved Analog-to-Digital Converters describes the design of a high performance time-interleaved ADC, with much attention for practical design aspects, aiming at both industry and research. Measurements show best-inclass performance with a sample-rate of 1.8 GS/s, 7.9 ENOBs and a power efficiency of 1 pJ/conversion-step.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a structured treatment of the key principles and techniques for enabling efficient processing of deep neural networks (DNNs). DNNs are currently widely used for many artificial intelligence (AI) applications, including computer vision, speech recognition, and robotics. While DNNs deliver state-of-the-art accuracy on many AI tasks, it comes at the cost of high computational complexity. Therefore, techniques that enable efficient processing of deep neural networks to improve key metrics—such as energy-efficiency, throughput, and latency—without sacrificing accuracy or increasing hardware costs are critical to enabling the wide deployment of DNNs in AI systems. The book includes background on DNN processing; a description and taxonomy of hardware architectural approaches for designing DNN accelerators; key metrics for evaluating and comparing different designs; features of DNN processing that are amenable to hardware/algorithm co-design to improve energy efficiency and throughput; and opportunities for applying new technologies. Readers will find a structured introduction to the field as well as formalization and organization of key concepts from contemporary work that provide insights that may spark new ideas.

Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of nature is often through nonuniform observations in space or time. In space, one normally observes the important features of an object, such as edges. The less important features are interpolated. History is a collection of important events that are nonuniformly spaced in time. Historians infer between events (interpolation) and politicians and stock market analysts forecast the future from past and present events (extrapolation). The 20 chapters of Nonuniform Sampling: Theory and Practice contain contributions by leading researchers in nonuniform and Shannon sampling, zero crossing, and interpolation theory. Its practical applications include NMR, seismology, speech and image coding, modulation and coding, optimal content, array processing, and digital filter design. It has a tutorial outlook for practising engineers and advanced students in science, engineering, and mathematics. It is also a useful reference for scientists and engineers working in the areas of medical imaging, geophysics, astronomy, biomedical engineering, computer graphics, digital filter design, speech and video processing, and phased array radar.
