Claim 14:
15. A non-transitory computer-readable media storing executable instructions that when executed by a controller cause a method of determining an efficiency of a charge pump under test (PUT) to be performed, the method comprising:
providing a first charge pump clock signal to a first charge pump to control a supply of a predetermined output current being drawn by a load connected to the first charge pump;
determining a first number of clock edges of the first charge pump clock signal over a first period of time that the predetermined output current is drawn by the load;
after the PUT has been cascaded to the first charge pump, providing a second charge pump clock signal to the first charge pump to control an output current generated by the first charge pump;
determining a second number of clock edges of the second charge pump clock signal over a second period of time having substantially the same duration as the first period of time; and
determining the efficiency of the PUT based on the first number of clock edges and the second number of clock edges.
