Analysis and simulation of a cascaded delta delta–sigma modulator [PDF]

open access: yesComputer Standards & Interfaces, 2001
This paper discusses a cascaded delta delta-sigma modulator, in which a delta-sigma modulator cancels out the error of a delta modulator. Analysis and simulation show that the modulator outperforms conventional modulators of similar order when the input process is correlated.

Reduced Complexity MASH Delta-Sigma Modulator.

open access: yesIEEE Trans. Circuits Syst. II Express Briefs, 2007
A reduced complexity digital multi-stage noise shaping (MASH) delta-sigma modulator for fractional-N frequency synthesizer applications is proposed. A long word is used for the first modulator in a MASH structure; the sequence length is maximized by setting the least significant bit of the input to 1; shorter words are used in subsequent stages ...

A Multiplierless DC-Blocker for Single-Bit Sigma-Delta Modulated Signals

open access: yesEURASIP Journal on Advances in Signal Processing, 2007
The DC content in single-bit domain is both undesirable and hard to remove. In this paper we propose a single-bit multiplierless DC-blocker structure. The input is assumed to be sigma-delta modulated bitstream.
