On the implementation of input-feedforward delta-sigma modulators [PDF]
IEEE Transactions on Circuits and Systems II: Express Briefs, 2006 This brief addresses some practical issues on the implementation of the input-feedforward delta-sigma modulators. First, the timing constraint imposed by the input-feedforward path is identified and a possible method to relax the constraint is proposed.

Delta-Sigma Modulator based multiplier
IEICE Electronics Express, 2009 In this paper, a new technique is proposed for multiplication of two sampled low frequency analog signals and the result is in digital form. Out of the two signals, one signal is fed to the input of typical second order, ΔΣ Modulator (DSM). The operating period of the DSM circuit is varied directly in proportion to the absolute amplitude of the second ...
