摘　　要：详细分析了电荷泵的动态工作特性 ,给出了电荷泵电压上升时间及瞬态电流与电路的关系。基于这些分析 ,可以得到电荷泵的功耗来源和电压上升与充电电容的关系 ,同时还对电荷泵电路的电压产生的限制作出了分析。文末给出了整个分析结果与 SPICE模拟结果的对照 ,从结果可以看出整个分析大致反应了电荷泵的实际工作情况 ,正确地体现了电荷泵的工作原理。Charge pump dynamic analysis is analyzed, and the relationship between the voltage rising time and transient current to circuit is given. Based on this analysis, we can get the source of the charge pump power dissipation and the relation between the voltage rising time and the charging capacitors. The limitation of the charge pump generated voltage is also given. The results obtained from this analysis are confirmed by HSPICE, from which the actual operation of charge pump is illustrated by this model.
