摘要 | This paper presents a new digital compensation scheme for MASH (cascaded) sigma-delta modulators (SigmaDeltaMs) with 1-bit quantizer. The compensation scheme is designed based on the well-known internal model principle and H-infinity control theory. For numerical illustration, we concentrate on a MASH 2-1 SigmaDeltaM architecture for low and middle frequencies applications. Comparisons between the proposed SigmaDeltaM and the conventional one are made, which reveal that the proposed SigmaDeltaM outperforms the conventional one in several aspects - signal-to-noise ratio (SNR), dynamic range (DR), output swing. |
