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).

Available in PDF, EPUB and Kindle. Book excerpt: This book presents high-performance data transmission over plastic optical fibers (POF) using integrated optical receivers having good properties with multilevel modulation, i.e. a higher sensitivity and higher data rate transmission over a longer plastic optical fiber length. Integrated optical receivers and transmitters with high linearity are introduced for multilevel communication. For binary high-data rate transmission over plastic optical fibers, an innovative receiver containing an equalizer is described leading also to a high performance of a plastic optical fiber link. The cheap standard PMMA SI-POF (step-index plastic optical fiber) has the lowest bandwidth and the highest attenuation among multimode fibers. This small bandwidth limits the maximum data rate which can be transmitted through plastic optical fibers. To overcome the problem of the plastic optical fibers high transmission loss, very sensitive receivers must be used to increase the transmitted length over POF. The plastic optical fiber limited bandwidth problem can be decreased by using multilevel signaling like multilevel pulse amplitude modulation or by using an equalizer for binary data transmission.

This book was released on 2012-12-06 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Very fast advances in IC technologies have brought new challenges into the physical design of integrated systems. The emphasis on system performance, in lately developed applications, requires timing and power constraints to be considered at each stage of physical design. The size of ICs is decreasing continuously, and the density of power dissipated in the circuits is growing rapidly. The first challenge is the Information Technology where new materials, devices, telecommunication and multimedia facilities are developed. The second one is the Biomedical Science and Biotechnology. The utilisation of bloodless surgery is possible now because of wide micro-sensors and micro-actuators application. Nowadays, the modern micro systems can be implanted directly into the human body and the medicine can be applied right in the proper time and place in the patient body. The low-power devices are being developed particularly for medical and space applications. This has created for designers in all scientific domains new possibilities which must be handed down to the future generations of designers. In this spirit, we organised the Fourth International Workshop "MIXED DESIGN OF INTEGRATED CIRCUITS AND SYSTEMS" in order to provide an international forum for discussion and the exchange of information on education, teaching experiences, training and technology transfer in the area of microelectronics and microsystems.

Available in PDF, EPUB and Kindle. Book excerpt: Analog design is one of the more difficult aspects of electrical engineering. The main reason is the apparently vague decisions an experienced designer makes in optimizing his circuit. To enable fresh designers, like students electrical engineering, to become acquainted with analog circuit design, structuring the analog design process is of utmost importance. Structured Electronic Design: Negative-Feedback Amplifiers presents a design methodology for negative-feedback amplifiers. The design methodology enables to synthesize a topology and to, at the same time, optimize the performance of that topology. Key issues in the design methodology are orthogonalization, hierarchy and simple models. Orthogonalization enables the separate optimization of the three fundamental quality aspects: noise, distortion and bandwidth. Hierarchy ensures that the right decisions are made at the correct level of abstraction. The use of simple models, results in simple calculations yielding maximum-performance indicators that can be used to reject wrong circuits relatively fast. The presented design methodology divides the design of negative-feedback amplifiers in six independent steps. In the first two steps, the feedback network is designed. During those design steps, the active part is assumed to be a nullor, i.e. the performance with respect to noise, distortion and bandwidth is still ideal. In the subsequent four steps, an implementation for the active part is synthesized. During those four steps the topology of the active part is synthesized such that optimum performance is obtained. Firstly, the input stage is designed with respect to noise performance. Secondly, the output stage is designed with respect to clipping distortion. Thirdly, the bandwidth performance is designed, which may require the addition of an additional amplifying stage. Finally, the biasing circuitry for biasing the amplifying stages is designed. By dividing the design in independent design steps, the total global optimization is reduced to several local optimizations. By the specific sequence of the design steps, it is assured that the local optimizations yield a circuit that is close to the global optimum. On top of that, because of the separate dedicated optimizations, the resource use, like power, is tracked clearly. Structured Electronic Design: Negative-Feedback Amplifiers presents in two chapters the background and an overview of the design methodology. Whereafter, in six chapters the separate design steps are treated with great detail. Each chapter comprises several exercises. An additional chapter is dedicated to how to design current sources and voltage source, which are required for the biasing. The final chapter in the book is dedicated to a thoroughly described design example, showing clearly the benefits of the design methodology. In short, this book is valuable for M.Sc.-curriculum Electrical Engineering students, and of course, for researchers and designers who want to structure their knowledge about analog design further.
