Abstract

A new architecture is presented for a multibit oversampled σ-Δ A/D convenor. A novel feedback arrangement is employed to reduce the sensitivity of the overall resolution to the nonlnearity of the multibit DAC. Simulations confirm the improved performance achieved by the proposed structure.
