Comparative study of the MASH digital delta-sigma modulators

Xu, Tao and Condon, Marissa (2009) Comparative study of the MASH digital delta-sigma modulators. In: PRIME 2009 - Ph.D. Research in Microelectronics and Electronics, 12-17 July 2009, Cork, Ireland. ISBN 978-1-4244-3733-7

Abstract
The paper focuses on the Multi-stAge noise SHaping (MASH) digital delta-sigma modulator (DDSM) that employs multi-moduli (MM-MASH). Different architectures of the MASH DDSM are compared. In particular, it is proven that a higherorder error feedback modulator (EFM) has the same sequence length as a first-order EFM (EFM1) in an MM-MASH. In addition, the method that is required to setup the quantisation moduli of the MM-MASH is introduced. The theory is validated by simulation.
