摘要：

During the last decade there was an explosion in the field of mobile multimedia devices that led to the emergence of new and very complex requirements for the producers of integrated circuits (IC's). Practically, many of the difficulties localized in the systems made with multiple discrete IC's have moved one level down, inside the IC itself ( this is how the concept of System on Chip came up). This paper presents exactly such an example in which the audio section of a mobile phone must coexist with the intermediate radio frequency section in a single IC. It starts by mentioning the technical challenges facing this request, followed by an introduction of the fundamental theories used in finding the most efficient solution.
