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. %@ 0013-5194 %T Extending minimum sequence length invariantly to constant input for MASH 1-1-1 digital delta–sigma modulator %B Electronics Letters %D October 2017 %V 53 %N 21 %P 1394-1396 %I Institution of Engineering and Technology %U https://digital-library.theiet.org/;jsessionid=1vbelx6llqd6n.x-iet-live-01content/journals/10.1049/el.2017.1777 %G EN
