Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Advances in consumer electronics are creating a demand for high speed, low and medium resolution, analog to digital converters. For reasons of cost and integration the circuitry should be compatible with standard digital CMOS. Low power operation is critical in portable equipment, but also improves product reliability and reduces the cost of packaging. The flash converter is perhaps the simplest conversion architecture, however its area and complexity increase exponentially with resolution, making signal distribution complicated, and power consumption prohibitive. Pipeline techniques are well suited to CMOS but at high sampling rates these converters become complex, and large. Moreover CMOS pipeline converters usually require precision capacitors. Folding and interpolating converters offer the speed of flash type devices but at a fraction of the area and power consumption. Until recently, all published folding and interpolating designs have been implemented in bipolar technology. The performance of bipolar based folding converters has come to rival that of other topologies. In this work we describe a CMOS folding and interpolating architecture. The circuitry can be fabricated with standard digital CMOS processing. A CMOS, folding and interpolating, analog-to-digital conversion architecture is presented. The architecture is fully compatible with standard digital CMOS. For speed the analog circuitry is fully differential, continuous time, current mode and open loop. To insure low noise the digital circuitry is implemented using CMOS current steering logic. A 125Ms/s 8 bit and a 150Ms/s 6 bit prototype are described. Both prototypes were implemented in 1um CMOS. The 8 bit converter occupies approximately 4mm2 and dissipates 250mW from a 5V supply, the 6 bit device is half this size and dissipates 55mW. Both devices can function with a supply voltage of 3.3V."

This book was released on 2006-01-14 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main trends of microelectronics is toward design for integrated systems, i.e., system-on-a-chip (SoC) or system-on-silicon (SoS). Due to this development, design techniques for mixed-signal circuits become more important than before. Among other devices, analog-to-digital and digital-to-analog converters are the two bridges between the analog and the digital worlds. Besides, low-power design technique is one of the main issues for embedded systems, especially for hand-held applications. Modular Low-Power, High-Speed CMOS Analog-to-Digital Converter for Embedded Systems aims at design techniques for low-power, high-speed analog-to-digital converter processed by the standard CMOS technology. Additionally this book covers physical integration issues of A/D converter integrated in SoC, i.e., substrate crosstalk and reference voltage network design.

Available in PDF, EPUB and Kindle. Book excerpt: High-speed and low resolution analog-to-digital converters (ADC) are key elements in the read channel of optical and magnetic data storage systems. The required resolution is about 6-7 bits while the sampling rate and effective resolution bandwidth requirements increase with each generation of storage system. Folding is a technique to reduce the number of comparators used in the flash architecture. By means of an analog preprocessing circuit in folding A/D converters the number of comparators can be reduced significantly. Folding architectures exhibit low power and low latency as well as the ability to run at high sampling rates. Folding ADCs employing interpolation schemes to generate extra folding waveforms are called "Folding and Interpolating ADC" (F & I ADC). The aim of this research is to increase the input bandwidth of high speed conversion, and low latency F & I ADC. Behavioral models are developed to analyze the bandwidth limitation at the architecture level. A front-end sample-and-hold unit is employed to tackle the frequency multiplication problem, which is intrinsic for all F & I ADCs. Current-mode signal processing is adopted to increase the bandwidth of the folding amplifiers and interpolators, which are the bottleneck of the whole system. An operational transconductance amplifier (OTA) based folding amplifier, current mirror-based interpolator, very low impedance fast current comparator are proposed and designed to carry out the current-mode signal processing. A new bit synchronization scheme is proposed to correct the error caused by the delay difference between the coarse and fine channels. A prototype chip was designed and fabricated in 0.35 ơm CMOS process to verify the ideas. The S/H and F & I ADC prototype is realized in 0.35 [mu]m double-poly CMOS process (only one poly is used). Integral nonlinearity (INL) is 1.0 LSB and Differential nonlinearity (DNL) is 0.6 LSB at 110 KHz. The ADC occupies 1.2mm2 active area and dissipates 200mW (excluding 70mW of S/H) from 3.3V supply. At 300MSPS sampling rate, the ADC achieves no less than 6 ENOB with input signal lower than 60MHz. It has the highest input bandwidth of 60MHz reported in the literature for this type of CMOS ADC with similar resolution and sample rate.

This book was released on 2010-10-29 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the fast advancement of CMOS fabrication technology, more and more signal-processing functions are implemented in the digital domain for a lower cost, lower power consumption, higher yield, and higher re-configurability. This has recently generated a great demand for low-power, low-voltage A/D converters that can be realized in a mainstream deep-submicron CMOS technology. However, the discrepancies between lithography wavelengths and circuit feature sizes are increasing. Lower power supply voltages significantly reduce noise margins and increase variations in process, device and design parameters. Consequently, it is steadily more difficult to control the fabrication process precisely enough to maintain uniformity. The inherent randomness of materials used in fabrication at nanoscopic scales means that performance will be increasingly variable, not only from die-to-die but also within each individual die. Parametric variability will be compounded by degradation in nanoscale integrated circuits resulting in instability of parameters over time, eventually leading to the development of faults. Process variation cannot be solved by improving manufacturing tolerances; variability must be reduced by new device technology or managed by design in order for scaling to continue. Similarly, within-die performance variation also imposes new challenges for test methods. In an attempt to address these issues, Low-Power High-Resolution Analog-to-Digital Converters specifically focus on: i) improving the power efficiency for the high-speed, and low spurious spectral A/D conversion performance by exploring the potential of low-voltage analog design and calibration techniques, respectively, and ii) development of circuit techniques and algorithms to enhance testing and debugging potential to detect errors dynamically, to isolate and confine faults, and to recover errors continuously. The feasibility of the described methods has been verified by measurements from the silicon prototypes fabricated in standard 180nm, 90nm and 65nm CMOS technology.

Download or read book High-Speed Analog-to-Digital Conversion written by Michael J. Demler and published by Elsevier. This book was released on 2012-12-02 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the theory and applications of high-speed analog-to-digital conversion. An analog-to-digital converter takes real-world inputs (such as visual images, temperature readings, and rates of speed) and transforms them into digital form for processing by computer. This book discusses the design and uses of such circuits, with particular emphasis on improving the speed of the conversion process and the accuracy of its output--how well the output is a corresponding digital representation of the output*b1input signal. As computers become increasingly interfaced to the outside world, "ADC" techniques will become ever more important.
