A Behavior Model of a Dickson Charge Pump Circuit for Designing a Multiple Charge Pump System Distributed in LSIs

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.
