The paper proposes a novel structure for a MASH digital delta-sigma modulator (DDSM) in order to achieve a long sequence length. The expression for the sequence length is derived. The condition to produce the maximum sequence length is also stated. It is proved that the modulator output only
depends on the structure of the first-order error feedback
modulator (EFM1) which is the first stage of a Multi-stAge noise SHaping (MASH) modulator.
