  • Determining charge pump efficiency using clock edge counting
    Patent number: 11927635
    Abstract: A charge pump test configuration and corresponding method of operation are disclosed for determining charge pump efficiency without needing to obtain direct current measurements. A first number of clock edges (CEs) of a clock signal supplied to a first charge pump is determined over a period of time for a predetermined output current. The first charge pump is then connected with a charge pump under test (PUT) in a cascaded manner such that an output current of the first charge pump is supplied to the PUT as an input current. A second number of CEs of a clock signal supplied to the first charge pump is determined over the same period of time for the same predetermined output current from the PUT. The efficiency of the PUT can then be determined as the ratio of the first number of CEs to the second number of CEs, or vice versa.
