Eynde F.O., Sansen W. Analog Interfaces for Digital Signal Processing Systems

Springer, 1993. — 141.The field of analog integrated circuit design is undergoing rapid evolution. The pervasiveness of digital processing has considerably modified the micro-system architectures: the analog part of complex mixed systems is more and more pushed at the boundary limits of the processing chain. Moreover, the increased performance of digital circuits, in terms of accuracy and speed, are making the specification requirements of analog circuits very strict. In addition to this, the technology, supply voltage and power consumption of analog circuits must be compatible with those, typical for digital circuits. Therefore, in a few words, analog circuits are becoming complex and specialised interfaces between the real world and digital signal processing domains.
This technological evolution should be accompanied by an equivalently fast evolution in designer competencies. Knowledge of complicated signal handling should be quickly replaced by know-how of simple but very accurate and very fast signal processing and a solid background in data conversion techniques. All of this through the use of the CMOS (and possibly BiCMOS) technology.
Obviously, a new approach is needed in the design methodology; an approach that, on one hand must return the transistor-level requirements to achieve advanced performances, and on the other hand focuses the designer only on the few methods that are suitable for mixed-mode technology implementations. This new trend is a reality that can not be overlooked or ignored. It is, therefore, gratifying to acknowledge the work done for this publication. It is an answer to the new needs of the analog designer's community.The Power Consumption of CMOS Wideband Amplifiers
