Zusammenfassung:A sigma-delta analog-to-digital converter comprises first and second injection branches (202, 204) and first and second feedback branches (221, 222) connected to an integration node (120). The first and second injection branches are configured to provide a charge injection from different input quantities selected from a differential voltage signal, a capacitance dependent signal and a current dependent signal. The first and second feedback branches are configured to provide a feedback charge injection of a fixed voltage signal (VRP, VRN) or a differential voltage signal (VI1, VBE1).
