  • Abstract
    A double-sampled delta-sigma (DeltaSigma) modulator topology is proposed that can relax the critical timing constraints in the modulator feedback path. The speed requirements of the quantiser and dynamic element matching logic are thus greatly reduced. To verify the effectiveness of the proposed topology, a second-order double-sampled DeltaSigma modulator is designed and simulated.
