Abstract
A calibration operation determines a resistance of a sense resistor in a POE system. A voltage measurement is taken with a first current flowing through the sense resistor. A second voltage measurement is taken with a second current flowing through the resistor. A resistance value of the sense resistor is determined based on a voltage difference between the first and second voltage measurements and a current difference between the first current and the second currents.
