Parallel architecture for analog-to-information converters via multibit delta-sigma modulation

This paper presents a parallel architecture for analog-to-information converters. The converter´s architecture shifts most of the computational burden to the digital domain to take full advantage of deep-submicron IC fabrication technologies. The analog part of the converter is composed of a single multibit first-order Delta-Sigma modulator. The proposed architecture is validated through numerical simulations. The results show that signal recovery improves significantly when a 2-bit and a 3-bit Delta-Sigma modulators are employed.
