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.

This book deals with modeling and implementation of high performance, current-steering D/A-converters for digital transceivers in nanometer CMOS technology. In the first part, the fundamental performance limitations of current-steering DACs are discussed. Based on simplified models, closed-form expressions for a number of basic non-ideal effects are derived and tested. With the knowledge of basic performance limits, the converter and system architecture can be optimized in an early design phase, trading off circuit complexity, silicon area and power dissipation for static and dynamic performance. The second part describes four different current-steering DAC designs in standard 130 nm CMOS. The converters have a resolution in the range of 12-14 bits for an analog bandwidth between 2.2 MHz and 50 MHz and sampling rates from 100 MHz to 350 MHz. Dynamic-Element-Matching (DEM) and advanced dynamic current calibration techniques are employed to minimize the required silicon area.

The Analogue-to-digital converter (ADC) is the most pervasive block in electronic systems. With the advent of powerful digital signal processing and digital communication techniques, ADCs are fast becoming critical components for system’s performance and flexibility. Knowing accurately all the parameters that characterise their dynamic behaviour is crucial, on one hand to select the most adequate ADC architecture and characteristics for each end application, and on the other hand, to understand how they affect performance bottlenecks in the signal processing chain. Dynamic Characterisation of Analogue-to-Digital Converters presents a state of the art overview of the methods and procedures employed for characterising ADCs’ dynamic performance behaviour using sinusoidal stimuli. The three classical methods – histogram, sine wave fitting, and spectral analysis – are thoroughly described, and new approaches are proposed to circumvent some of their limitations. This is a must-have compendium, which can be used by both academics and test professionals to understand the fundamental mathematics underlining the algorithms of ADC testing, and as an handbook to help the engineer in the most important and critical details for their implementation.

High-speed Photodiodes in Standard CMOS Technology describes high-speed photodiodes in standard CMOS technology which allow monolithic integration of optical receivers for short-haul communication. For short haul communication the cost aspect is important , and therefore it is desirable that the optical receiver can be integrated in the same CMOS technology as the rest of the system. If this is possible then ultimately a singe-chip system including optical inputs becomes feasible, eliminating EMC and crosstalk problems, while data rate can be extremely high. The problem of photodiodes in standard CMOS technology it that they have very limited bandwidth, allowing data rates up to only 50Mbit per second. High-speed Photodiodes in Standard CMOS Technology first analyzes the photodiode behaviour and compares existing solutions to enhance the speed. After this, the book introduces a new and robust electronic equalizer technique that makes data rates of 3Gb/s possible, without changing the manufacturing technology. The application of this technique can be found in short haul fibre communication, optical printed circuit boards, but also photodiodes for laser disks.

The book gives an overview of the state-of-the-art in SigmaDelta design and of the challenges for future realizations. It provides an understanding of the fundamental power efficiency of SigmaDelta converters. In addition, it presents an analysis of the power consumption in the decimation filter. Understanding these power/performance trade-offs, it becomes clear that straight-forward digitization of a conditioning channel, i.e. exchanging analog for digital conditioning, comes at a major power penalty.

Systematic Design of Sigma-Delta Analog-to-Digital Converters describes the issues related to the sigma-delta analog-to-digital converters (ADCs) design in a systematic manner: from the top level of abstraction represented by the filters defining signal and noise transfer functions (STF, NTF), passing through the architecture level where topology-related performance is calculated and simulated, and finally down to parameters of circuit elements like resistors, capacitors, and amplifier transconductances used in individual integrators. The systematic approach allows the evaluation of different loop filters (order, aggressiveness, discrete-time or continuous-time implementation) with quantizers varying in resolution. Topologies explored range from simple single loops to multiple cascaded loops with complex structures including more feedbacks and feedforwards. For differential circuits, with switched-capacitor integrators for discrete-time (DT) loop filters and active-RC for continuous-time (CT) ones, the passive integrator components are calculated and the power consumption is estimated, based on top-level requirements like harmonic distortion and noise budget. This unified, systematic approach to choosing the best sigma-delta ADC implementation for a given design target yields an interesting solution for a high-resolution, broadband (DSL-like) ADC operated at low oversampling ratio, which is detailed down to transistor-level schematics. The target audience of Systematic Design of Sigma-Delta Analog-to-Digital Converters are engineers designing sigma-delta ADCs and/or switched-capacitor and continuous-time filters, both beginners and experienced. It is also intended for students/academics involved in sigma-delta and analog CAD research.

Institutional book, not really for bookstore catalogue The book contains valuable information structured to provide insight on how to design SC sigma-delta modulators. It presents architectures, circuits, models, methods and practical considerations for the design of high-performance low-pass switched-capacitor (SC) sigma-delta A/D interfaces for mixed-signal CMOS ASICs. The main focus of the book is on cascade architectures. It differs from other books in the complete, in-depth coverage of SC circuit errors.
