The introduction of IC technology has led to a revolution in the integration of electronic systems. Nowadays millions of transistors can be put in a very small volume, together forming complex functions. This has opened up the road to many new products, like today’s personal computers, digital TV, and many battery powered products, like PDAs, advanced wrist watches, MP3 players and the mobile phone. In this book the mobile phone will be further investigated. More specifically, this book will zoom-in on the ADC in the receive path of a mobile phone.
In Chap. 1 the work presented in this book will be motivated by making an inventory of important trends in the mobile phone industry, from the application and the technology side. These trends will be related to the implications these trends put on the ADC used in the transceiver of a mobile phone. Market trends for cellular and connectivity terminals will be translated into system quality indicators, which will be used for the system specification and qualification through the book. From the implementation side, Moore’s law will be used to explore the technology trends of mainstream CMOS technologies used for the integration of the transceiver, and the implications these have on the implementation of circuits on silicon. Furthermore, Shannon’s theorem will show that time resolution is in favor to amplitude resolution, which pleads for the use of a ΣΔ ADC architecture for the transceiver’s ADC, the ΣΔ converter.
