发明名称 Dynamic Switching Approach to Reduce Area and Power Consumption of High Voltage Charge Pumps
摘要 A charge pump system uses a dynamic switching approach, where the pump connections are independent of the load for each output. One large pump is designed to be shared between all of the outputs for use during the ramp up during recovery, with each output level also have one designated pump to maintain its level when under regulation. Each small pump is designed with capability that can maintain its output at its regulation level. Each of these pumps can be tailored to the corresponding output level, such as the number of stages being higher in the pump to supply the higher output level. The large pump unit is constructed to be ample to provide sufficient drive to be able to assist in the ramp up phase for all of the outputs and has as many switches needed to connect the pump with all the needed outputs.
