Abstract
A circuit includes a binary weighted divider having a first set of switches coupled in series between an input node and a feedback node. The first set of switches is configured to set a feedback voltage at the feedback node in response to activating or deactivating respective switches in the first set of switches. A set of compensation switches is coupled to the first set of switches. The set of compensation switches is configured to reduce resistance of one or more of the respective switches in the first set of switches that are activated by activating one or more switches in the set of compensation switches to provide one or more respective parallel current paths for each of the switches in the first set of switches that are activated.
