      High-order cascade multi-bit Σ∆ modulators for high-speed A/D conversion  [Presentation]

      Río Fernández, Rocío del; Medeiro Hidalgo, Fernando; Pérez Verdú, Belén; Rodríguez Vázquez, Ángel Benito (Universidad Carlos III, 1998)
      The use of Sigma-Delta (Σ∆) modulation for analog-to-digital conversion (ADC) in the communication frequency range is evaluated. Two high-order multi-bit architectures are proposed to achieve +12-bit dynamic range at ...
