For four decades the evolution of integrated circuits has followed Moore’s law, according to which the number of transistors per square millimeter of silicon doubles every 18 months. At the same time transistors have become faster, making possible ever-increasing clock rates in digital circuits. This trend seems set to continue for at least another decade without slowing down. Thus, in the near future the processing power of digital circuits will continue to increase at an accelerating pace. For analog circuits the evolution of technology is not as beneficial. Thus, there is a trend to move signal processing functions from the analog domain to the digital one, which, besides allowing for a higher level of accuracy, provides savings in power consumption and silicon area, increases robustness, speeds up the design process, brings flexibility and programmability, and increases the possibilities for design reuse. In many applications the input and output signals of the system are inherently analog, preventing all-digital realizations; at the very least a conversion between analog and digital is needed at the - terfaces. Typically, moving the analog-digital boundary closer to the outside world increases the bit rate across it. In telecommunications systems the trend to boost bit rates is based on - ploying widerbandwidths and a higher signal-to-noise ratio. At the same time radio architectures in many applications are evolving toward software-defined radio, one of the main characteristics of which is the shifting of the anal- digital boundary closer to the antenna.

Analog-to-Digital Converters (ADCs) play an important role in most modern signal processing and wireless communication systems where extensive signal manipulation is necessary to be performed by complicated digital signal processing (DSP) circuitry. This trend also creates the possibility of fabricating all functional blocks of a system in a single chip (System On Chip - SoC), with great reductions in cost, chip area and power consumption. However, this tendency places an increasing challenge, in terms of speed, resolution, power consumption, and noise performance, in the design of the front-end ADC which is usually the bottleneck of the whole system, especially under the unavoidable low supply-voltage imposed by technology scaling, as well as the requirement of battery operated portable devices. Generalized Low-Voltage Circuit Techniques for Very High-Speed Time-Interleaved Analog-to-Digital Converters will present new techniques tailored for low-voltage and high-speed Switched-Capacitor (SC) ADC with various design-specific considerations.

Design of Low-Voltage Low-Power CMOS Delta-Sigma A/D Converters investigates the feasibility of designing Delta-Sigma Analog to Digital Converters for very low supply voltage (lower than 1.5V) and low power operation in standard CMOS processes. The chosen technique of implementation is the Switched Opamp Technique which provides Switched Capacitor operation at low supply voltage without the need to apply voltage multipliers or low VtMOST devices. A method of implementing the classic single loop and cascaded Delta-Sigma modulator topologies with half delay integrators is presented. Those topologies are studied in order to find the parameters that maximise the performance in terms of peak SNR. Based on a linear model, the performance degradations of higher order single loop and cascaded modulators, compared to a hypothetical ideal modulator, are quantified. An overview of low voltage Switched Capacitor design techniques, such as the use of voltage multipliers, low VtMOST devices and the Switched Opamp Technique, is given. An in-depth discussion of the present status of the Switched Opamp Technique covers the single-ended Original Switched Opamp Technique, the Modified Switched Opamp Technique, which allows lower supply voltage operation, and differential implementation including common mode control techniques. The restrictions imposed on the analog circuits by low supply voltage operation are investigated. Several low voltage circuit building blocks, some of which are new, are discussed. A new low voltage class AB OTA, especially suited for differential Switched Opamp applications, together with a common mode feedback amplifier and a comparator are presented and analyzed. As part of a systematic top-down design approach, the non-ideal charge transfer of the Switched Opamp integrator cell is modeled, based upon several models of the main opamp non-ideal characteristics. Behavioral simulations carried out with these models yield the required opamp specifications that ensure that the intended performance is met in an implementation. A power consumption analysis is performed. The influence of all design parameters, especially the low power supply voltage, is highlighted. Design guidelines towards low power operation are distilled. Two implementations are presented together with measurement results. The first one is a single-ended implementation of a Delta-Sigma ADC operating with 1.5V supply voltage and consuming 100 &mgr;W for a 74 dB dynamic range in a 3.4 kHz bandwidth. The second implementation is differential and operates with 900 mV. It achieves 77 dB dynamic range in 16 kHz bandwidth and consumes 40 &mgr;W. Design of Low-Voltage Low-Power CMOS Delta-Sigma A/D Converters is essential reading for analog design engineers and researchers.

One of the main trends of microelectronics is toward design for integrated systems, i.e., system-on-a-chip (SoC) or system-on-silicon (SoS). Due to this development, design techniques for mixed-signal circuits become more important than before. Among other devices, analog-to-digital and digital-to-analog converters are the two bridges between the analog and the digital worlds. Besides, low-power design technique is one of the main issues for embedded systems, especially for hand-held applications. Modular Low-Power, High-Speed CMOS Analog-to-Digital Converter for Embedded Systems aims at design techniques for low-power, high-speed analog-to-digital converter processed by the standard CMOS technology. Additionally this book covers physical integration issues of A/D converter integrated in SoC, i.e., substrate crosstalk and reference voltage network design.

This volume of Analog Circuit Design concentrates on three topics: Low-Power Low-Voltage Design; Integrated Filters, and Smart Power. The book comprises six papers on each topic written by internationally recognised experts. These papers have a tutorial nature aimed at improving the design of analog circuits. The book is divided into three parts: Part I, Low-Power Low-Voltage Design, describes the latest techniques for producing analog circuits with low-voltage low-power requirements. These circuits have an important role to play in the increasing trend towards portable products, where battery life is an important design factor. The papers cover design techniques for amplifiers, analog-to-digital converters, micro-power analog filters and medical devices. Part II, Integrated Filters, presents papers which detail nearly all known techniques to construct integrated filters. These filters all use resistors and capacitors to obtain the filtering function due to the low quality of inductors in silicon. Integration of the filtering function on chips is important to reduce system cost and provide greater accuracy. Part III, Smart Power, illustrates up-to-date techniques for implementing thermal detectors and protection networks to improve reliability and the lifetime of many analog devices. These devices are more specifically those with different analog blocks operating at different temperatures. Smart Power is thus never limited to circuit design only, but must also include packaging and cooling considerations; it is system design. Analog Circuit Design is an essential reference source for analog design engineers wishing to keep abreast with the latest developments in the field. The tutorial nature of the contributions also makes the book suitable for use in an advanced course.

Compact Low-Voltage and High-Speed CMOS, BiCMOS and Bipolar Operational Amplifiers discusses the design of integrated operational amplifiers that approach the limits of low supply voltage or very high bandwidth. The resulting realizations span the whole field of applications from micro-power CMOS VLSI amplifiers to 1-GHz bipolar amplifiers. The book presents efficient circuit topologies in order to combine high performance with simple solutions. In total twelve amplifier realizations are discussed. Two bipolar amplifiers are discussed, a 1-GHz operational amplifier and an amplifier with a high ratio between the maximum output current and the quiescent current. Five amplifiers have been designed in CMOS technology, extremely compact circuits that can operate on supply voltages down to one gate-source voltage and two saturation voltages which equals about 1.4 V and, ultimate-low-voltage amplifiers that can operate on supply voltages down to one gate-source voltage and one saturation voltage which amounts to about 1.2 V. In BiCMOS technology five amplifiers have been designed. The first two amplifiers are based on a compact topology. Two other amplifiers are designed to operate on low supply voltages down to 1.3 V. The final amplifier has a unity-gain frequency of 200 MHz and can operate down to 2.5 V. Compact Low-Voltage and High-Speed CMOS, BiCMOS and Bipolar Operational Amplifiers is intended for the professional analog designer. Also, it is suitable as a text book for advanced courses in amplifier design.

Static and Dynamic Performance Limitations for High Speed D/A Converters discusses the design and implementation of high speed current-steering CMOS digital-to-analog converters. Starting from the definition of the basic specifications for a D/A converter, the elements determining the static and dynamic performance are identified. Different guidelines based on scientific derivations are suggested to optimize this performance. Furthermore, a new closed formula has been derived to account for the influence of the transistor mismatch on the achievable resolution of the current-steering D/A converter. To allow a thorough understanding of the dynamic behavior, a new factor has been introduced. Moreover, the frequency dependency of the output impedance introduces harmonic distortion components which can limit the maximum attainable spurious free dynamic range. Finally, the last part of the book gives an overview on different existing transistor mismatch models and the link with the static performance of the D/A converter.
