Abstract
This chapter proposes a novel design methodology for a Multi-stAge noise SHaping (MASH) digital delta–sigma modulator (DDSM) which employs multi-moduli. The structure is termed the MM-MASH. The adequacy and benefit of using such a structure is demonstrated. In particular, the sequence length is lengthened if the quantizer modulus of the first-order error feedback modulator (EFM1) of each stage are co-prime numbers. An expression for the sequence length of an MM-MASH is derived.
