Abstract
During operation of an analog filter having one or more filter stages is configured to operate in a first configuration. Configuring the analog filter to operate in the first filter configuration includes configuring one or both of i) a filter response of the analog filter and ii) a filter bandwidth of the analog filter. A first set of one or more direct current (DC) offset correction codes corresponding to the first filter configuration are retrieved from a memory. The one or more DC offset correction codes in the first set are converted to one or more first analog DC offset correction signals. While operating the analog filter configured in the first configuration, the one or more first analog DC offset correction signals are applied to the one or more filter stages of the analog filter.
