An anti-aliasing filter that incorporates a sampler is proposed to precede noise-shaping analog-to-digital converters (ADCs), such as discrete-time ΔΣ modulators. The architecture of the proposed anti-aliasing filter is inspired by the implicit anti-aliasing filtering property of CT ΔΣ modulators. However, contrary to CT ΔΣ modulators, the proposed(More)
—In this paper we present a framework for robust design of continuous-time Σ∆ modulators. The approach allows to find a modulator which maintains its performance (stability, guaranteed peak SNR,. . .) over all the foreseen parasitic effects, provided it exists. For this purpose, we have introduced the S-figure as a criterion for the robustness of a(More)
