Available in PDF, EPUB and Kindle. Book excerpt: The Analog to Digital Converters represent one half of the link between the world we live in - analog - and the digital world of computers, which can handle the computations required in digital signal processing. These devices are mathematically very complex due to their nonlinear behavior and thus fairly difficult to analyze without the use of simulation tools. High Speed A/D Converters: Understanding Data Converters Through SPICE presents the subject from the practising engineer's point of view rather than from the academic's point of view. A practical approach is emphasized. High Speed A/D Converters: Understanding Data Converters Through SPICE is intended as a learning tool by providing building blocks that can be stacked on top of each other to build higher order systems. The book provides a guide to understanding the various topologies used in A/D converters by suggesting simple methods for the blocks used in an A/D converter. The converters discussed throughout the book constitute a class of devices called undersampled or Nyquist converters. The tools used in deriving the results presented are: TopSpice® by Penzar - a mixed mode SPICE simulator - version 5.90. The files included in Appendix A were written for this tool. However, most circuit files need only minor adjustments to be used on other SPICE simulators such as PSpice, Hspice, IS_Spice and Micro-Cap IV; Mathcad 2000 - Professional by Mathsoft. This tool is very useful in performing FFT analysis as well as drawing some of the graphs. Again, the mathcad files are included to help the user analyze the data. High Speed A/D Converters: Understanding Data Converters Through SPICE not only supplies the models for the A/D converters for SPICE program but also describes the physical reasons for the converter's performance.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with the design and implementation of an 8-bit, 1-Gsample/s folding-interpolating analog-to-digital converter using a conventional 0.5 [mu]m self-aligned, double polysilicon bipolar process with maximum unity gain cutoff frequency fT of 25GHz. The high-speed and high-resolution A/D converter has applications in direct IF sampling receivers for wideband communications systems. The folding-interpolating architecture offers an optimum solution for Gsample/s, high-resolution A/D converters in terms of system complexity, power dissipation and chip area. The use of a silicon bipolar process allows the integration of Gsample/s ADCs with DSP systems usually realized by silicon CMOS or BiCMOS processes. The 8-bit, 1-Gsample/s A/D converter consists of a reference ladder; four folding blocks for the fine quantizer and one folding block for the coarse quantizer; interpolation resistive strings; a comparator array; a digital encoder including an EXOR array, an error-correction stage, and a 31-to-5 OR ROM; and a coarse quantizer. All circuit blocks are integrated on one chip. The chip area of the circuitry is 2.5mm x 3.5mm including bonding pads. The converter exhibits a better than 7-bit ENOB with an input signal frequency of 200MHz and at a sampling rate of 1-Gsample/s The maximum power dissipation of the ADC is 2.5W using a 5-V power supply.

This book was released on 2012-12-06 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analog-to-digital (A/D) and digital-to-analog (D/A) converters provide the link between the analog world of transducers and the digital world of signal processing, computing and other digital data collection or data processing systems. Several types of converters have been designed, each using the best available technology at a given time for a given application. For example, high-performance bipolar and MOS technologies have resulted in the design of high-resolution or high-speed converters with applications in digital audio and video systems. In addition, high-speed bipolar technologies enable conversion speeds to reach the gigaHertz range and thus have applications in HDTV and digital oscilloscopes. Integrated Analog-to-Digital and Digital-to-Analog Converters describes in depth the theory behind and the practical design of these circuits. It describes the different techniques to improve the accuracy in high-resolution A/D and D/A converters and also special techniques to reduce the number of elements in high-speed A/D converters by repetitive use of comparators. Integrated Analog-to-Digital and Digital-to-Analog Converters is the most comprehensive book available on the subject. Starting from the basic elements of theory necessary for a complete understanding of the design of A/D and D/A converters, this book describes the design of high-speed A/D converters, high-accuracy D/A and A/D converters, sample-and-hold amplifiers, voltage and current reference sources, noise-shaping coding and sigma-delta converters. Integrated Analog-to-Digital and Digital-to-Analog Converters contains a comprehensive bibliography and index and also includes a complete set of problems. This book is ideal for use in an advanced course on the subject and is an essential reference for researchers and practicing engineers.

Available in PDF, EPUB and Kindle. Book excerpt: Many interesting design trends are shown by the six papers on operational amplifiers (Op Amps). Firstly. there is the line of stand-alone Op Amps using a bipolar IC technology which combines high-frequency and high voltage. This line is represented in papers by Bill Gross and Derek Bowers. Bill Gross shows an improved high-frequency compensation technique of a high quality three stage Op Amp. Derek Bowers improves the gain and frequency behaviour of the stages of a two-stage Op Amp. Both papers also present trends in current-mode feedback Op Amps. Low-voltage bipolar Op Amp design is presented by leroen Fonderie. He shows how multipath nested Miller compensation can be applied to turn rail-to-rail input and output stages into high quality low-voltage Op Amps. Two papers on CMOS Op Amps by Michael Steyaert and Klaas Bult show how high speed and high gain VLSI building blocks can be realised. Without departing from a single-stage OT A structure with a folded cascode output, a thorough high frequency design technique and a gain-boosting technique contributed to the high-speed and the high-gain achieved with these Op Amps. . Finally. Rinaldo Castello shows us how to provide output power with CMOS buffer amplifiers. The combination of class A and AB stages in a multipath nested Miller structure provides the required linearity and bandwidth.

Available in PDF, EPUB and Kindle. Book excerpt: The motivation behind this work is to target the demand for high-speed medium-resolution ADCs for satellite communication systems. An 8-bit, 12.5GS/s folding-interpolating ADC was designed in 0.25mum, 190GHz SiGe BiCMOS technology from IHP. The ADC consists of a THA, a reference resistor ladder, folding amplifiers, an interpolating resistor string, a comparator array, a digital encoder, a coarse quantizer and a bit synchronizer.Post-layout simulation results of the ADC verify that its performance meets all the required specifications. By comparison to other high-speed ADCs, implemented in SiGe technologies, the present design features the highest sampling rate for 8-bit resolution ADCs to date with a good FOM (12.9pJ/conversion).The THA and the comparator were implemented experimentally and characterized to verify their performance and to ascertain the possibility of implementing the complete ADC. The experimental results meet the expected specifications and indicate that both circuits are suitable for the implementation of the ADC.

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."
