SUMMARY This paper proposes novel feedforward architecture of the second-order multibit ΔΣAD modulator with single DAC-feedback topol-ogy. The ΔΣAD modulator realizes high resolution by oversampling and noise shaping techniques. However, its SNDR (Signal to Noise and Distortion Ratio) is limited by the dynamic range of the input signal and non-idealities of(More)
