This book was released on 2014-09-22 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to the design of adaptive equalization solutions integrated in standard CMOS technology for high-speed serial links. Since continuous-time equalizers offer various advantages as an alternative to discrete-time equalizers at multi-gigabit rates, this book provides a detailed description of continuous-time adaptive equalizers design - both at transistor and system levels-, their main characteristics and performances. The authors begin with a complete review and analysis of the state of the art of equalizers for wireline applications, describing why they are necessary, their types, and their main applications. Next, theoretical fundamentals of continuous-time adaptive equalizers are explored. Then, new structures are proposed to implement the different building blocks of the adaptive equalizer: line equalizer, loop-filters, power comparator, etc. The authors demonstrate the design of a complete low-power, low-voltage, high-speed, continuous-time adaptive equalizer. Finally, a cost-effective CMOS receiver which includes the proposed continuous-time adaptive equalizer is designed for 1.25 Gb/s optical communications through 50-m length, 1-mm diameter plastic optical fiber (POF).

This book was released on 2013-09-06 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the trade-offs involved in designing direct RF digitization receivers for the radio frequency and digital signal processing domains. A system-level framework is developed, quantifying the relevant impairments of the signal processing chain, through a comprehensive system-level analysis. Special focus is given to noise analysis (thermal noise, quantization noise, saturation noise, signal-dependent noise), broadband non-linear distortion analysis, including the impact of the sampling strategy (low-pass, band-pass), analysis of time-interleaved ADC channel mismatches, sampling clock purity and digital channel selection. The system-level framework described is applied to the design of a cable multi-channel RF direct digitization receiver. An optimum RF signal conditioning, and some algorithms (automatic gain control loop, RF front-end amplitude equalization control loop) are used to relax the requirements of a 2.7GHz 11-bit ADC. A two-chip implementation is presented, using BiCMOS and 65nm CMOS processes, together with the block and system-level measurement results. Readers will benefit from the techniques presented, which are highly competitive, both in terms of cost and RF performance, while drastically reducing power consumption.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation develops an unclocked receiver analog decision-feedback equalizer (ADFE) circuit architecture and topology and implements the circuit in 0.18-um CMOS to enable 10-Gb/sec serial baseband data transmission over FR-4 backplane and optical fibre. The ADFE overcomes the first feedback-loop latency challenge of traditional digital and mixed-signal DFEs by separating data re-timing from equalization and also eliminates the need for clock-recovery prior to decision-feedback equalization. The ADFE enables 10-Gb/sec decision-feedback equalization using a 0.18-um CMOS process, the first to do so to the author s knowledge. A tuneable current-mode-logic (CML) feedback-loop is designed to enable first post-cursor cancellation for a range of data-rates and to have external control over loop latency over variations in process, voltage and temperature. CML design techniques are used to minimize current consumption and achieve the required voltage swing for decision-feedback to take place. The all-analog equalizer consumes less power and area than comparable state-of-the art DFEs.

Download or read book High Speed CMOS Circuits for Optical Receivers written by Jafar Savoj and published by Springer. This book was released on 2001-05-31 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the exponential growth of the number of Internet nodes, the volume of the data transported on the backbone has increased with the same trend. The load of the global Internet backbone will soon increase to tens of terabits per second. This indicates that the backbone bandwidth requirements will increase by a factor of 50 to 100 every seven years. Transportation of such high volumes of data requires suitable media with low loss and high bandwidth. Among the available transmission media, optical fibers achieve the best performance in terms of loss and bandwidth. High-speed data can be transported over hundreds of kilometers of single-mode fiber without significant loss in signal integrity. These fibers progressively benefit from reduction of cost and improvement of perf- mance. Meanwhile, the electronic interfaces used in an optical network are not capable of exploiting the ultimate bandwidth of the fiber, limiting the throughput of the network. Different solutions at both the system and the circuit levels have been proposed to increase the data rate of the backbone. System-level solutions are based on the utilization of wave-division multiplexing (WDM), using different colors of light to transmit s- eral sequences simultaneously. In parallel with that, a great deal of effort has been put into increasing the operating rate of the electronic transceivers using highly-developed fabrication processes and novel c- cuit techniques.
Download or read book Low Power Techniques for CMOS Wireline Receivers written by Abishek Manian and published by . This book was released on 2016 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the ever-increasing need for high throughput from chip-to-chip I/Os, wireline transceivers are being pushed to operate at higher speeds. With the increase in data rates, the power consumption of broadband receivers has become critical in multi-lane applications like the Gigabit Ethernet. It is therefore desirable to minimize the power drawn by all of the building blocks. This work introduces a 40-Gb/s CMOS wireline receiver that advances the art by achieving a tenfold reduction in power and an efficiency of 0.35 mW/Gb/s. An innovative aspect of the proposed NRZ receiver is our "minimalist" approach, which recognizes that every additional stage in the data or clock path consumes more power and limits the bandwidth. The minimalist mentality avoids multiple stages in the front-end continuous-time linear equalizer (CTLE), quadrature oscillators in the clock and data recovery (CDR) circuit, clock or data buffers, or phase interpolation. Moreover, building blocks are shared among different functions so as to reduce the number of current paths between VDD and ground. Using charge-steering techniques extensively, the receiver contains only a few static bias currents adding up to about 6 mA. The minimalist approach also leads to a small footprint, about 110 um x 175 um, for the entire receiver, making it possible to design a multi-lane system in a small area and with short interconnects. This receiver incorporates a one-stage CTLE with 5.5-dB boost, a one-tap discrete-time linear equalizer (DTLE) with 5.4-dB boost, a half-rate CDR circuit, a two-tap half-rate/quarter-rate decision-feedback equalizer, a 1:4 deserializer, and two new latch topologies. Since in recent designs, the CTLE draws significant power, this work introduces the DTLE as an efficient means of creating a high-frequency boost with only 0.3 mW. Fabricated in 45-nm CMOS technology, the receiver achieves a BER

Download or read book Digital Systems Engineering written by William J. Dally and published by Cambridge University Press. This book was released on 2008-04-24 with total page 944 pages. Available in PDF, EPUB and Kindle. Book excerpt: What makes some computers slow? Why do some digital systems operate reliably for years while others fail mysteriously every few hours? How can some systems dissipate kilowatts while others operate off batteries? These questions of speed, reliability, and power are all determined by the system-level electrical design of a digital system. Digital Systems Engineering presents a comprehensive treatment of these topics. It combines a rigorous development of the fundamental principles in each area with real-world examples of circuits and methods. The book not only serves as an undergraduate textbook, filling the gap between circuit design and logic design, but can also help practising digital designers keep pace with the speed and power of modern integrated circuits. The techniques described in this book, once used only in supercomputers, are essential to the correct and efficient operation of any type of digital system.
Download or read book High Speed Serdes Devices and Applications written by David Robert Stauffer and published by Springer Science & Business Media. This book was released on 2008-12-19 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: The simplest method of transferring data through the inputs or outputs of a silicon chip is to directly connect each bit of the datapath from one chip to the next chip. Once upon a time this was an acceptable approach. However, one aspect (and perhaps the only aspect) of chip design which has not changed during the career of the authors is Moore’s Law, which has dictated substantial increases in the number of circuits that can be manufactured on a chip. The pin densities of chip packaging technologies have not increased at the same pace as has silicon density, and this has led to a prevalence of High Speed Serdes (HSS) devices as an inherent part of almost any chip design. HSS devices are the dominant form of input/output for many (if not most) high-integration chips, moving serial data between chips at speeds up to 10 Gbps and beyond. Chip designers with a background in digital logic design tend to view HSS devices as simply complex digital input/output cells. This view ignores the complexity associated with serially moving billions of bits of data per second. At these data rates, the assumptions associated with digital signals break down and analog factors demand consideration. The chip designer who oversimplifies the problem does so at his or her own peril.
