 Abstract—In this paper, a digital background calibration technique is proposed to improve the resolution of discrete-time multi-stage noise-shaping (MASH) sigma-delta (ΣΔ) modulators. The circuit imperfections of switched-capacitor discrete-time integrators (DTIs) degenerate the modulator output resolution, especially in MASH structures due to the(More)
