System Quality Indicators
The integration of systems on a chip to many battery powered portable applications like the cellular phone, wireless products, MP3 players and so on. The constant drive to improve these applications and to include extra features has enormously increased the pace with which new generation portable products are introduced on the market. Keeping its main function, extra demands are put on the system realizing this function. Smarter integrated system solutions, which are cheaper, smaller, more power efficient, robust to interference, more flexible, etc. are required. In Chap. 2, these additional system requirements are captured in five quality indicators which indicate the quality of the (integrated) system, and which will help to structure the analysis of complex systems. In this chapter the quality indicators are used to motivate why it can be advantageous to shift analog functionality into the digital domain which implicates the need for high dynamic range and high bandwidth analog-digital interfaces.
