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

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