In this paper, a long sequence length, reduced complexity MASH 1-1-1 digital delta-sigma modulator (DDSM) suitable for fractional-N frequency synthesizer applications is presented. Good shaping of quantization noise is achieved by using the state of art MASH structure for a digital third-order delta-sigma modulator, meanwhile, the hardware required for this modulator is considerably reduced by recoding all carry output signal from accumulators. The functional operation of the modulator is confirmed by simulation.
