DOI: 10.1080/03772063.2018.1473056
Abstract: ABSTRACT Based on output-referred error model of passive integrator (PI), the current study proposes a digital adaptive calibration to compensate passive delta-sigma modulator error. Due to signal attenuation in the modulator loop, the PI transfer… read more here.

DOI: 10.1109/tcsi.2019.2941526
Abstract: This paper presents inherently accurate digital calibration of ADC non-linearity, which requires neither absolute accuracy of a signal for calibration nor any modification of ADC core, hence enabling the use of existing ADC IP cores.… read more here.
