  • Abstract
    A new architecture is presented for a multibit oversampled Sigma - Delta A/D convertor. A novel feedback arrangement is employed to reduce the sensitivity of the overall resolution to the nonlinearity of the multibus DAC. Simulations confirm the improved performance achieved by the proposed structure.
