Mixed Signal Design — Design Issues —

  • H. J. Casier


The continuously increasing chip density makes it now possible to integrate more functions and even a complete system on a single chip. Since a complete system contains analog and digital signal processing and is often controlled and supported by an embedded microcore, this evolution has favoured mixed signal chips, that combine these functions on a single chip. At the same time, mixed signal design itself has changed. In the eighties, the analog circuits dominated the area of the mixed signal chips. Nowadays, the situation is reversed and the digital circuits dominate the area. As a consequence, the design issues for mixed signal chips have changed accordingly. Three of these design issues are discussed below. The strong demand to use a digital technology for the mixed signal chip, the increased interference between digital and analog circuits and the concurrent design of analog, digital and embedded software for the mixed system-on-achip.
