  • Abstract
    A scheme for achieving adaptive reduction in the order of the loop filter of usual high-order, single-stage, single-bit Delta-Sigma (ΔΣ) modulators is proposed in order to improve their performance. The resulting ΔΣ modulators can recover from instability effectively, having also an extended input signal range in comparison to that of the corresponding conventional ΔΣ modulators.
