Book excerpt: In this work, the author investigated circuit techniques to reduce the power consumption of Successive Approximation Register Analog-to-Digital Converter (SAR-ADC). The author developed four low-power SAR-ADC design techniques, which are: (1) Low-power SAR-ADC design with split voltage reference, (2) Charge recycling techniques for low-power SAR-ADC design, (3) Low-power SAR-ADC design using two-capacitor arrays, (4) Power reduction techniques by dynamically minimizing SAR-ADC conversion cycles. Matlab simulations are performed to investigate the power saving by the proposed techniques. Simulation results show that significant power reduction can be achieved by using the developed techniques. In addition, design issues such as area overhead, design complexity associated with the proposed low-power techniques are also discussed in the thesis.

This book was released on 2010 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: As the use of digital systems continues to grow, there is an increasing need to convert analog information into the digital domain. Successive Approximation Register (SAR) analog-to-digital converters are used extensively in this regard due to their high resolution, small die area, and moderate conversion speeds. However, capacitor mismatch within the SAR converter is a limiting factor in its accuracy and resolution. Without some form of calibration, a SAR converter can only reasonably achieve an accuracy of 10 bits. The Split-ADC technique is a digital, deterministic, background self-calibration algorithm that can be applied to the SAR converter. This thesis describes the circuit design and physical implementation of a novel 16-bit 1MS/s SAR analog-to-digital converter for use with the Split-ADC calibration algorithm. The system was designed using the Jazz 0.18um CMOS process, successfully operates at 1MS/s, and consumes a die area of 1.2mm2. The calibration algorithm was applied, showing an improvement in the overall accuracy of the converter.

Download or read book Accelerated Successive Approximation Technique for Analog to Digital Converter Design written by Ram Harshvardhan Radhakrishnan and published by . This book was released on 2015 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis work presents a novel technique to reduce the number of conversion cycles for Successive Approximation register (SAR) Analog to Digital Converters (ADC), thereby potentially improving the conversion speed as well as reducing its power consumption. Conventional SAR ADCs employ the binary search algorithm and they update only one bound, either the upper or lower bound, of the search space during one conversion cycle. The proposed method, referred to as the Accelerated-SAR or A-SAR, is capable of updating both the lower and upper bounds in a single conversion cycle. Even in cases that it can update only one bound, it does more aggressively. The proposed technique is implemented in a 10-bit SAR ADC circuit with 0.5V power supply and rail-to-rail input range. To cope with the ultra-low voltage design challenge, Time-to-Digital conversion techniques are used in the implementation. Important design issues are also discussed for the charge scaling array and Voltage Controlled Delay Lines (VCDL), which are important building blocks in the ADC implementation.

Download or read book Design Techniques for Low Power High Speed Successive Approximation Analog-to-digital Converters written by Jiaming Lin and published by . This book was released on 2013 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents two high-speed pipeline successive approximation analog-to-digital converters (SAR ADCs). Capacitive DACs and resistive DACs are utilized in these two pipeline SAR ADCs, respectively. The pipeline SAR ADC with capacitive DACs can save 50% switching power compared with other time-interleaved SAR ADCs since the total capacitance of the DACs in this ADC is more than 50% less than the conventional time-interleave ones. Several switching techniques are implemented to alleviate the impact from the parasitic capacitance and improve the performance. The pipeline SAR ADC with resistive DACs overcomes the influence from the parasitic capacitance with negligible static power consumption on the resistive DACs. Also, the complicated switching techniques can be avoided to simplify the timing logic. To verify the above two architectures, two chips were designed and fabricated in 40nm CMOS process. Finally, a new architecture of multi-step capacitive-splitting SAR ADC is proposed for low power applications. By using two identical capacitor-splitting capacitor arrays, the switching power and capacitor area can be reduced significantly.

This book was released on 2013-05-13 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews recent developments of interleaved Successive Approximation Analog-to-Digital converters (SAR) in deep sub-micron CMOS technologies. The discussion covers design tradeoffs and degrees of freedom related to the impact of extensive interleaving with many SAR units on bandwidth, noise, linearity, and spurious performance. The impact of interleaving mismatches on representative broadband and multi-carrier narrowband signals is also discussed. Next, two examples are given demonstrating how interleaving with many ADCs can be transformed from a weakness to a strength. The first example concerns low spurious performance enabled by redundant SAR converters and randomization of their operation. The second example presents spectral sensing techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Today digital signal processing systems use advanced CMOS technologies requiring the analog-to-digital converter to be implemented in the same (digital) technology. Such an implementation requires special circuit techniques. Furthermore the susceptibility of converters to ground bounce or digital noise is an important design criterion. In this part different converters and conversion techniques are described that are optimized for receiver applications. Part II, Sensor and Actuator Interfaces, interfaces for sensors and actuators shape the gates through which information is acquired from the real world into digital information systems, and vice versa. The interfaces should include analog signal conditioning, analog-to-digital conversion, digital bus interfaces and data-acquisition networks. To simplify the use of data-acquisition systems additional features should be incorporated, like self-test, and calibration

Download or read book Low-power Successive Approximation Analog to Digital Converter with Digital Calibration written by Wei Li and published by . This book was released on 2014 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: IC designers are continuously facing the challenges from reduced CMOS feature sizes and supply voltages. ADCs that deliver satisfactory resolutions/speeds while utilizing the state-of-the-art technologies to save power are in high demand. The analog circuits are more and more assisted by various digital calibration techniques to get boosted performances. This dissertation is focused on a low-power 12-bit 12.5-MS/s successive approximation (SAR) ADC with a couple of calibration schemes. The performances of the proposed SAR ADC are enhanced in two directions. To reduce the power dissipation, a power saving strategy has been proposed. Also, several foreground calibration methods for SAR ADCs have been proposed to reduce power dissipation and enhance conversion accuracy. The design was fabricated in 40nm CMOS technology. Measurement results after calibration showed a SFDR of 82.2 dB, and a THD improvement of 22.5 dB. Finally, two new schemes to realize teraohm on-chip resistance are presented. One of the schemes utilizes a switched-capacitor array, and the other utilizes a switch-capacitor ladder. Using these schemes, large resistances can be fabricated with standard CMOS process in an affordable chip area.

This book was released on 2012-12-06 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oversampling techniques based on sigma-delta modulation are widely used to implement the analog/digital interfaces in CMOS VLSI technologies. This approach is relatively insensitive to imperfections in the manufacturing process and offers numerous advantages for the realization of high-resolution analog-to-digital (A/D) converters in the low-voltage environment that is increasingly demanded by advanced VLSI technologies and by portable electronic systems. In The Design of Low-Voltage, Low-Power Sigma-Delta Modulators, an analysis of power dissipation in sigma-delta modulators is presented, and a low-voltage implementation of a digital-audio performance A/D converter based on the results of this analysis is described. Although significant power savings can typically be achieved in digital circuits by reducing the power supply voltage, the power dissipation in analog circuits actually tends to increase with decreasing supply voltages. Oversampling architectures are a potentially power-efficient means of implementing high-resolution A/D converters because they reduce the number and complexity of the analog circuits in comparison with Nyquist-rate converters. In fact, it is shown that the power dissipation of a sigma-delta modulator can approach that of a single integrator with the resolution and bandwidth required for a given application. In this research the influence of various parameters on the power dissipation of the modulator has been evaluated and strategies for the design of a power-efficient implementation have been identified. The Design of Low-Voltage, Low-Power Sigma-Delta Modulators begins with an overview of A/D conversion, emphasizing sigma-delta modulators. It includes a detailed analysis of noise in sigma-delta modulators, analyzes power dissipation in integrator circuits, and addresses practical issues in the circuit design and testing of a high-resolution modulator. The Design of Low-Voltage, Low-Power Sigma-Delta Modulators will be of interest to practicing engineers and researchers in the areas of mixed-signal and analog integrated circuit design.

Available in PDF, EPUB and Kindle. Book excerpt: A book is like a window that allows you to look into the world. The window is shaped by the author and that makes that every window presents a unique view of the world. This is certainly true for this book. It is shaped by the topics and the projects throughout my career. Even more so, this book re?ects my own style of working and thinking. That starts already in Chap. 2. When I joined Philips Research in 1979, many of my colleagues used little paper notebooks to keep track of the most used equations and other practical things. This notebook was the beginning for Chap. 2: a collection of topics that form the basis for much of the other chapters. Chapter2 is not intended to explain these topics, but to refresh your knowledge and help you when you need some basics to solve more complex issues. In the chapters discussing the fundamental processes of conversion, you will r- ognize my preoccupation with mathematics. I really enjoy ?nding an equation that properly describes the underlying mechanism. Nevertheless mathematics is not a goalonitsown:theequationshelptounderstandthewaythevariablesareconnected to the result. Real insight comes from understanding the physics and electronics. In the chapters on circuit design I have tried to reduce the circuit diagrams to the s- plest form, but not simpler. . . I do have private opinions on what works and what should not be applied.
