Abstract
A current measurement circuit is disclosed. The current measurement circuit includes first and second circuit branches coupled to a circuit node through which current is to be measured. During a first period, the first circuit branch converts the current into a first voltage. During a second period, the second circuit branch converter the current into a second voltage. An analog-to-digital converter is configured to convert the first and second voltages into digital values indicative of the measured current. A control circuit is configured to alternately select one of the first and second branches during the generation of the digital values.
