This letter presents a novel cascade ΣΔ modulator architecture that employs inter-stage resonation to increase its effective resolution compared to traditional cascades while presenting very relaxed output swing requirements and, subsequently, high robustness to non-linearities of the amplifiers. In addition, the use of loop filters based on Forward-Euler integrators, instead of Backward-Euler integrators as proposed in earlier approaches, simplifies the switched-capacitor implementation and makes the proposed architecture very suited for wideband A/D conversion.
