  • Abstract
    We propose both adder and multiplier circuits for bit-stream signal processing customized for tri-level sigma-delta modulated signals. These architectures are the 2-bit extensions from the existing 1-bit bit-stream adders and multipliers, and are shown to offer better signal-to-noise performance. Field-programmable gate array implementations then confirm their efficacy.
