Abstract
An embodiment of a voltage-measuring circuit includes: a first resistor connected to a first measurement node; a second resistor connected to the first resistor and a second measurement node; a configuration switch configured to, in response to a control signal, selectively interconnect the first and second resistors, during enable and disable phases of the control signal respectively, into and out of either a parallel or a series configuration; and a control and measurement circuit configured to provide the control signal, receive a first measurement voltage from the first and second measurement nodes during the enable phase, and receive a second measurement voltage from the first and second measurement nodes during the disable phase.
