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.

Abstract: An input circuit includes an input stage having an input node and a direct-current (DC) amplifier coupled to the input node. The input circuit also includes an alternating-current (AC) amplifier coupled to an output node of the DC amplifier. The input circuit also includes a capacitor coupled between the input node and the output node of the DC amplifier. The input circuit also includes a voltage divider coupled to the DC amplifier and the AC amplifier. The voltage divider includes first resistor associated with the DC amplifier and a second resistor associated with the AC amplifier, where the first resistor is larger than the second resistor.
