Über dieses Buch

This book describes optical receiver solutions integrated in standard CMOS technology, attaining high-speed short-range transmission within cost-effective constraints. These techniques support short reach applications, such as local area networks, fiber-to-the-home and multimedia systems in cars and homes. The authors show how to implement the optical front-end in the same technology as the subsequent digital circuitry, leading to integration of the entire receiver system in the same chip. The presentation focuses on CMOS receiver design targeting gigabit transmission along a low-cost, standardized plastic optical fiber up to 50m in length. This book includes a detailed study of CMOS optical receiver design – from building blocks to the system level.

Chapter 1. Introduction
Abstract
This introductory chapter begins by exploring the history of physics, and in particular, of optical transmission. Then, the characteristics of such a transmission are analyzed, showing improvements and advantages over other possibilities. Thanks to these advantages, the range of applications covered by optical communications is increasing according to the requirements of transmission. In addition, a brief discussion of the chosen microelectronic technology is made. In the end, the outline of the work is offered showing the aims to be achieved.

Chapter 2. Optical Signal Transmission
Abstract
In this chapter, the principles of the optical signal transmission will be explored. First, the characteristics of transferred data will be analyzed, focusing on the pseudorandom bit sequence (PRBS), which is the typical signal used to test digital communication prototypes. Second, the fundamentals and the main types of optical fibers will be explained. Next, an overview of the core building blocks of an electro-optical transceiver front-end will be presented, explaining each component and its main requirements. Finally, the main key parameters of optical transmission from receiver’s point of view are defined, detailing the Gaussian noise model to determine the sensitivity with respect to the noise performance and the main penalty sources.

Chapter 3. Transimpedance Amplifier
Abstract
In this chapter, theoretical fundamentals regarding the main performances of the transimpedance amplifier, such as the optimum bandwidth owing to noise—ISI trade-off, its derivation from the selected topology—shunt-feedback TIA—and the transimpedance limit is presented. A comparison with others topologies—current-mode, common-gate and regulated cascade—and an introduction to input dynamic range extension techniques is also included. Next, the proposed design implemented in a standard 0.18 lm CMOS technology suitable for low-cost applications such as POF is explained. The scalability of our proposal for CMOS technologies with shorter channel length (90 nm) is demonstrated. Finally, the verification of both prototypes is presented.

Chapter 4. Post-Amplifier
Abstract
In this chapter, theoretical fundamentals regarding the amplifier core, such as multistage design and broadband techniques, and auxiliary loops, such as constant settling time for AGC and offset compensation, are presented. The proposed AGC amplifier is implemented in a low-cost CMOS technology, and its design is explained step-by-step. Finally, the verification of such a circuit is included.

Chapter 5. POF Receiver
Abstract
In this chapter, the main limitations of the low-cost optical channel, such as attenuation and bandwidth–length product, are introduced. The selected technique to compensate the low speed based on equalization is then analyzed. Thus, a fully integrated front-end receiver implemented in 0.18 lm CMOS technology, using the previously presented TIA and post-amplifier plus an adaptive equalizer and a photodiode monitor, is proposed for fiber-to-the-home (FTTH) applications at 1.25 Gb/s transmission speed on POF.

Chapter 6. Conclusions
Abstract
Throughout this book, the most relevant results and main conclusions have been summarized in the final discussion of each chapter. In this final chapter, the most significant contributions will be reported to give a general overview of the entire work.
