A novel implementation of dithered digital delta-sigma modulators via bus-splitting
Abstract
This paper presents a design methodology for dithered bus-splitting Multi stAge noise SHaping (MASH) digital delta-sigma modulators (DDSMs). Rules for selecting the appropriate wordlengths of the constituent DDSMs are derived which ensure that the spectral performance of the bus-splitting architecture is comparable to that of the conventional design but with less hardware. Behavioral simulations are presented which confirm the theoretical predictions. © 2011 IEEE.
