摘要：AbstractThis paper presents a continuous-time (CT) ΔΣ modulator employing an anti-windup (AW) feedback control technique to mitigate integrator overload and maintain an acceptable performance simultaneously. The proposed technique accommodates a large dynamic range and can be applied to multi-loop modulators. According to simulations, using AW augmentations, for a 50% higher dynamic range (DR), integrators do not overload and the signal-to-distortion-ratio (SNDR) drops less than 1dB from the maximum SNDR of the modulator.
