Systematic Design for Optimisation of Pipelined ADCs proposes and develops new strategies, methodologies and tools for designing low-power and low-area CMOS pipelined A/D converters. The task is tackled by following a scientifically-consistent approach. First of all, the state of the art in pipeline A/D converters is analysed with a double purpose: a) to identify the best suited among different strategies reported in literature and taking into account the objectives pursued; b) to identify the drawbacks of these strategies as a basic first step to improve them. Then, the book proposes a top-down design approach for implementing high-performance low-power and low-area CMOS pipelined A/D converters through: The conception, development and implementation of self-calibrated techniques to extend the linearity of some critical stages in the architecture of pipelined ADCs. The detailed analysis and modelling of some major non-idealities that limit the physical realisation of pipelined ADCs and the proposal, development and implementation of design methodologies to support systematic design of optimised instances of these converters which combine maximum performance with minimum power dissipation and minimum area occupation. GBP/LISTGBP Several implementations together with consistent measured results are presented. In particular, a practical realisation of a low-power 14-bit 5MS/s CMOS pipelined ADC with background analogue self-calibration is fully described. The proposed approach is fully in line with the best practice regarding the design of mixed-signal integrated circuits. On the one hand, drawbacks of currently existing solutions are overcame through innovative strategies and, on the other hand, the expert knowledge is packaged and made available for re-usability by the community of circuit designers. Finally, feasibility of the strategies and the associated encapsulated knowledge is granted through experimental validation of working silicon. Systematic Design for Optimisation of Pipelined ADCs serves as an excellent reference for analogue design engineers especially designers of low-power CMOS A/D converters. The book may also be used as a text for advanced reading on the subject.

Very large scale integration (VLSI) technologies are now maturing with a current emphasis toward submicron structures and sophisticated applications combining digital as well as analog circuits on a single chip. Abundant examples are found on today's advanced systems for telecom- munications, robotics, automotive electronics, image processing, intelli- gent sensors, etc .. Exciting new applications are being unveiled in the field of neural computing where the massive use of analog/digital VLSI technologies will have a significant impact. To match such a fast technological trend towards single chip ana- logi digital VLSI systems, researchers worldwide have long realized the vital need of producing advanced computer aided tools for designing both digital and analog circuits and systems for silicon integration. Ar- chitecture and circuit compilation, device sizing and the layout genera- tion are but a few familiar tasks on the world of digital integrated circuit design which can be efficiently accomplished by matured computer aided tools. In contrast, the art of tools for designing and producing analog or even analogi digital integrated circuits is quite primitive and still lack- ing the industrial penetration and acceptance already achieved by digital counterparts. In fact, analog design is commonly perceived to be one of the most knowledge-intensive design tasks and analog circuits are still designed, largely by hand, by expert intimately familiar with nuances of the target application and integrated circuit fabrication process. The techniques needed to build good analog circuits seem to exist solely as expertise invested in individual designers.

Multirate Switched-Capacitor Circuits for 2-D Signal Processing introduces the concepts of analog multirate signal processing for the efficient implementation of two-dimensional (2-D) filtering in integrated circuit form, particularly from the viewpoints of silicon area and power dissipation.

This excellent reference proposes and develops new strategies, methodologies and tools for designing low-power and low-area CMOS pipelined A/D converters. The task is tackled by following a scientifically-consistent approach. The book may also be used as a text for advanced reading on the subject.
