Pathological Elements in Analog Circuit Design


Book Description

This book is a compilation and a collection of tutorials and recent advances in the use of nullors (combinations of nullators and norators) and pathological mirrors in analog circuit and system design. It highlights the basic theory, trends and challenges in the field, making it an excellent reference resource for researchers and designers working in the synthesis, analysis, and design of analog integrated circuits. With its tutorial character, it can also be used for teaching. Singular elements such as nullors and pathological mirrors can arguably be considered as universal blocks since they can represent all existing analog building blocks, and they allow complex integrated circuits to be designed simply and effectively. These pathological elements are now used in a wide range of applications in modern circuit/system theory, and also in design practice.

Analog/RF and Mixed-Signal Circuit Systematic Design


Book Description

Despite the fact that in the digital domain, designers can take full benefits of IPs and design automation tools to synthesize and design very complex systems, the analog designers’ task is still considered as a ‘handcraft’, cumbersome and very time consuming process. Thus, tremendous efforts are being deployed to develop new design methodologies in the analog/RF and mixed-signal domains. This book collects 16 state-of-the-art contributions devoted to the topic of systematic design of analog, RF and mixed signal circuits. Divided in the two parts Methodologies and Techniques recent theories, synthesis techniques and design methodologies, as well as new sizing approaches in the field of robust analog and mixed signal design automation are presented for researchers and R/D engineers.




Analog Circuit Theory and Filter Design in the Digital World


Book Description

This textbook is designed for graduate-level courses, and for self-study, in analog and sampled-data, including switched-capacitor, circuit theory and design for ongoing, or active electrical engineers, needing to become proficient in analog circuit design on a system, rather than on a device, level. After decades of experience in industry and teaching this material in academic settings, the author has extracted many of the most important and useful features of analog circuit theory and design and presented them in a manner that is easy to digest and utilize. The methodology and analysis techniques presented can be applied to areas well beyond those specifically addressed in this book. This book is meant to enable readers to gain a 'general knowledge' of one aspect of analog engineering (e.g., that of network theory, filter design, system theory and sampled-data signal processing). The presentation is self-contained and should be accessible to anyone with a first degree in electrical engineering.

Analog Circuits


Book Description

This book includes recent research that focuses on analog integrated circuits and covers three main topics, namely: fundamentals, synthesis and performance. Eleven chapters are divided among these three topics as follows: Chapters One to Four are a part of fundamentals. The first chapter (The Next Generation of Nanomaterials for Designing Analog Integrated Circuits) describes new directions for applying nanomaterials for the design of modern analog circuits. Chapter Two (Application of Nullors in Designing Analog Circuits for Frequency Bandwidth) uses the pathological circuit element known as a nullor to design analog integrated circuits with frequency specifications to accomplish a desired bandwidth. Chapter Three (RC and RL to LC Circuit Conversion, and its Application in Poles and Zeros Identification) details an important property from circuit theory to estimate roots by performing conversions of passive elements. Chapter Four (Enhanced and Improved Symbolic Circuit Analysis Using MATLAB) relays the development of symbolic circuit analysis and focuses on enhancing an already developed symbolic tool to allow the symbolic analysis of large circuits. The synthesis of analog integrated circuits has been a challenge because there is no way to establish general rules to cover the gap between the behavioral and transistor circuit levels of abstraction. In this book, the second topic includes four chapters, from Five to Eight. Chapter Five (On the Synthesis of Sinusoidal Oscillators Using Nullors), just as in Chapter Two, uses the pathological circuit element known as a nullor to perform the synthesis of sinusoidal oscillators, which are quite useful in many electronic systems. Other kinds of oscillators are described in Chapter Six (Synthesis of SRCOs and Multi-Phase Oscillators from State Variables to their Implementation Using CMOS IC Technology) where the synthesis process identifies the resistor that controls the oscillating frequency and applies a state variable approach. Chapter Seven (Evolutionary Optimisation in the Design of CMOS Analog Integrated Circuits) shows the application of heuristics for circuit optimisation, and how it can be extended to bigger analog integrated circuits. Chapter Eight provides details on the synthesis and design of a CMOS harmonic mixer with output power management for narrowband and wideband wireless communications: the Bluetooth and UWB cases. The third part of this book is devoted to analog circuit performances and includes three chapters. Chapter Nine details the FPGA realisation of radio frequency (RF) power amplifier models. In this case, the system is modeled in the analog domain and implemented in the digital one. Chapter Ten White-Box Models of Optimal-Sized Solutions of Analog Integrated Circuits) generates analytical expressions for modeling the dominant behavior of CMOS analog circuits. Finally, Chapter Eleven (Radial Basis Function Surrogate Modeling for the Accurate Design of Analog Circuits) applies modern modeling approaches to accomplish real target specifications and to improve the design of reliable circuits.
