HIGH-EFFICIENCY CASCADE ΣΔ ADCs FOR SOFTWARE-DEFINED-RADIO MOBILE SYSTEMS

• Abstract:

  This paper discusses a number of techniques to implement efficient cascade ΣΔ modulators intended for low-voltage, wideband, multi-mode applications. Several architectural strategies - such as loop-filter order reconfiguration and concurrency . are embedded in SMASH topologies with unity signal transfer function and resonation in order to improve the performance, while keeping high robustness against circuit errors. The proposed ΣΔ architectures - properly combined with circuit-level reconfiguration and biasing adaptation techniques . constitute a suited solution to implement analog-to-digital converters in future software-defined radio mobile terminals.
