Abstract
A method includes providing a current flowing through a first flying capacitor of a switched-capacitor power converter, measuring a first voltage at one terminal of the first flying capacitor at a first voltage measurement time instant, measuring a second voltage at the one terminal of the first flying capacitor at a second voltage measurement time instant, and calculating a capacitance value of the first flying capacitor based on the first voltage, the second voltage, the first voltage measurement time instant and the second voltage measurement time instant.
