    Tools for Automated Design of ΣΔ Modulators  [Chapter of Book]

    Medeiro Hidalgo, Fernando; Rosa Utrera, José Manuel de la; Pérez Verdú, Belén; Rodríguez Vázquez, Ángel Benito (Springer, 1997)
    We present a set of CAD tools to design ΣΔ modulators. They use statistical optimization to calculate optimum specifications for the building blocks used in the modulators, and optimum sizes for the components in these ...
