Time-interleaved noise-shaping integrating quantisers

A new time-interleaved noise-shaping quantiser architecture is proposed. By employing a time-interleaving technique with a new path-coupling scheme, higher order of noise shaping and increased bandwidth are achieved. This general topology can be employed to synthesise any noise transfer function without the need for dedicated digital-to-analogue converters to extract the quantisation noise. Simulation results are provided to verify the effectiveness of this structure.
