Abstract
Devices and methods for measuring capacitance of a load. A device may include a ground connector configured to couple to ground and an output connector configured to couple to the load. The device may include a direct current (DC) supply arranged in a conduction path between the ground connector and the output connector wherein the DC supply is configured to apply a DC voltage and noise voltage onto the conduction path. The device may include a voltage monitor configured to monitor the noise voltage applied by the DC supply and the device may include a current monitor configured to measure current in the conduction path that results from the noise voltage. The device may include a capacitance module coupled to the current monitor and voltage monitor, the capacitance module configured to determine the capacitance based upon the monitored current and noise voltage.
