This brief discusses how each of multiple charge pump circuits in LSIs is designed in case where the power and ground line resistance is not negligible. A behavior model for a charge pump, including the local power and ground voltages as input parameters, is proposed and a systematic design methodology is then presented. A system designer can use the behavior model to determine the specifications on each pump and power and ground resistance for minimizing overall area.
