【摘要】 在分析一般电荷泵电路的基础上，提出一种新的电荷泵结构，并对它的工作原理及有关性能进行了详细分析研究。ＳＰＩＣＥ模拟结果表明，与原来的电路相比，在输出电压为１５ Ｖ的情况下，电荷泵的上升时间下降了４２ ％ ，负载能力提高了１２５ ％ ，为增大ＥＥＰＲＯＭ 的容量和提高数据的擦写速度提供了有利条件更多还原

【Abstract】 A charge pump circuit with a new structure is introduced in this paper.The performance of this pump circuit has been studied thoroughly.The simulated results show that the rising time decreases by 42% and driving ability rises by 125% comparing with the initial circuit when the output is 15V,which makes it easier to expand the capacity of EEPROM and to speed up the operation of EEPROM.更多还原
