Abstract

Examples relate to a circuit arrangement, a digital-to-analog conversion circuit, a charge-redistribution analog-to-digital conversion circuit and a method for controlling a circuit arrangement. The circuit arrangement comprises a plurality of charge stores. The plurality of charge stores is logically arranged in an array configuration comprising a plurality of logical columns of charge stores. The plurality of logical columns of charge stores comprise at least a first, a second, a third and a fourth column of charge stores. The circuit arrangement comprises a switching network operably coupled to the plurality of charge stores. The circuit arrangement comprises a control circuit configured to control the switching network. The control circuit is configured to affect a first circuit configuration in a first time segment and a second circuit configuration in a second time segment. The first circuit configuration and the second circuit configuration are different from one another. In the first circuit configuration the first and third columns of charge stores receive a first polarity component of a differential signal. In the first circuit configuration the second and fourth columns of charge stores receive a second polarity component of the differential signal. In the second circuit configuration the first and second columns of charge stores receive the first polarity component of the differential signal. In the second circuit configuration the third and fourth columns of charge stores receive the second polarity component of the differential signal.
