Time-mode circuits, where information is represented by time difference between digital events, offer a viable and technology-friendly means to realize mixed-mode circuits and systems in nanometer complementary metal-oxide semiconductor (CMOS) technologies. Various architectures of time-based signal processing and design techniques of CMOS time-mode circuits have emerged; however, an in-depth examination of the principles of time-based signal processing and design techniques of time-mode circuits has not been available—until now.CMOS Time-Mode Circuits and Systems: Fundamentals and Applications is the first book to deliver a comprehensive treatment of CMOS time-mode circuits and systems. Featuring contributions from leading experts, this authoritative text contains a rich collection of literature on time-mode circuits and systems.The book begins by presenting a critical comparison of voltage-mode, current-mode, and time-mode signaling for mixed-mode signal processing and then: Covers the fundamentals of time-mode signal processing, such as voltage-to-time converters, all-digital phase-locked loops, and frequency synthesizersInvestigates the performance characteristics, architecture, design techniques, and implementation of time-to-digital convertersDiscusses time-mode delta-sigma-based analog-to-digital converters, placing a great emphasis on time-mode quantizersIncludes a detailed study of ultra-low-power integrated time-mode temperature measurement systems CMOS Time-Mode Circuits and Systems: Fundamentals and Applications provides a valuable reference for circuit design engineers, hardware system engineers, graduate students, and others seeking to master this fast-evolving field.

Current-mode circuits, where information is represented by the branch currents of the circuits rather than the nodal voltages as of voltage-mode circuits, possess many unique and attractive characteristics over their voltage-mode counterparts including a small nodal time constant, high current swing in the presence of a low supply voltage, reduced distor­ tion, a low input impedance, a high output impedance, less sensitive to switching noise, and better ESD immunity. CMOS current-mode circuits have found increasing applications in telecommunication sys­ tems, instrumentation, analog signal processing, multiprocessors, high­ speed computer interfaces, and the backplane of complex electronic sys­ tems. This book deals with the analysis and design of continuous-time CMOS current-mode circuits for data communications over wire chan­ nels. CMOS current-mode sampled-data networks, such as switch- current circuits, and current-mode logic circuits, are excluded. The book is organized as the followings : Chapter 1 examines the distinct characteristics of ideal voltage-mode and current-mode circuits. The topology duaUty of these two classes of circuits is investigated using the concept of inter-reciprocity and adjoint network. A critical comparison of the input and output impedances, bandwidth, slew rate, propagation delay, signal swing, supply voltage sensitivity, and ESD sensitivity of voltage-mode and current-mode cir­ cuits is provided. Chapter 2 investigates design techniques that improve the perfor­ mance of low-voltage current-mode circuits including input impedance reduction, output impedance boosting, bandwidth enhancement, mis­ match compensation, power consumption reduction, and swing improve­ ment. Chapter 3 investigates the modeling of wire channels.

Many new topologies and circuit design techniques have emerged recently to improve the performance of active inductors, but a comprehensive treatment of the theory, topology, characteristics, and design constraint of CMOS active inductors and transformers, and a detailed examination of their emerging applications in high-speed analog signal processing and data communications over wire and wireless channels, is not available. This book is an attempt to provide an in-depth examination and a systematic presentation of the operation principles and implementation details of CMOS active inductors and transformers, and a detailed examination of their emerging applications in high-speed analog signal processing and data communications over wire and wireless channels.The content of the book is drawn from recently published research papers and are not available in a single, cohesive book. Equal emphasis is given to the theory of CMOS active inductors and transformers, and their emerging applications. Major subjects to be covered in the book include: inductive characteristics in high-speed analog signal processing and data communications, spiral inductors and transformers – modeling and limitations, a historical perspective of device synthesis, the topology, characterization, and implementation of CMOS active inductors and transformers, and the application of CMOS active inductors and transformers in high-speed analog and digital signal processing and data communications.
