Abstract (en)
[origin: WO2021078960A1] The present invention relates to a sigma-delta analogue-to-digital converter. The sigma-delta analogue-to-digital converter has a transconductance stage having a first, second and third connection. A capacitor is parallel-connected to the third connection. The sigma-delta analogue-to-digital converter also has a quantiser at the third connection of the transconductance stage with feedback by means of a voltage digital-to-analogue converter for feeding back a feedback signal to one of the connections of the transconductance stage.
