Annotation This book presents innovative solutions for the implementation of Sigma-Delta Modulation SDM based Analog-to-Digital Conversion ADC, required for the next generation of wireless hand-held terminals. These devices will be based on the so-calledmulti-standard transceiver chipsets, integrated in nanometer CMOS technologies. One of the most challenging and critical parts in such transceivers is the analog-digital interface, because of the assorted signal bandwidths and dynamic ranges that can be required to handle the A/D conversion for several operation modes. ÂThis book describes new adaptive and reconfigurable SDM ADC topologies, circuit strategies and synthesis methods, specially suited for multi-standard wireless telecom systems and future Software-defined-radios SDRs integrated in nanoscale CMOS. It is a practical book, going from basic concepts to the frontiers of SDM architectures and circuit implementations, which are explained in a didactical and systematic way. It gives a comprehensive overview of the state-of-the-art performance, challenges and practical solutions, providing the necessary insight to implement successful design, through an efficient design and synthesis methodology. Â Readers will learn a number of practical skills â from system-level design to experimental measurements and testing.
