Extending minimum sequence length invariantly to constant input for MASH 1-1-1 digital delta–sigma modulator
The architecture of MASH 1-1-1 digital delta–sigma modulator for lengthening minimum sequence length is proposed.

Summary: | The architecture of MASH 1-1-1 digital delta–sigma modulator for lengthening minimum sequence length is proposed. The first stage of the proposed multi-stage noise-shaping (MASH) delta–sigma modulator consists of two parts for the quantisation of input and the generation of long periodic feed-forward signal. The feed-forward signal results in extending the minimum sequence length invariantly to the input of the MASH 1-1-1 delta–sigma modulator. The noise power spectrum is analysed for preserving the noise-shaping capability of the MASH architecture. |
