A delta-sigma A/D converter includes a D/A converter realized with a mixed-mode comb filter connected in a feedback loop from the output of the A/D converter to the input of the A/D converter. The D/A converter is configured to predistort a feedback signal. The converter further includes an analogue filter at the input of the A/D converter. The analogue filter is configured to cancel the predistortion of the feedback signal. |
