本文介绍了一种在保持硅面积不变的情况下减小电荷泵上升时间的设计策略，该策略在负载电容小于电荷泵总电容时是有效的。该策略依赖于非常规的泵浦电容器尺寸，其将它们设置为不相等并遵循线性分布。该方法基于理论分析，并通过使用130 nm互补金属氧化物半导体（CMOS）标准技术的布局后模拟进行验证。仿真结果表明了所提出的设计策略的优点和理论的准确性。
This paper introduces a design strategy to reduce rise time of charge pumps maintaining equal the silicon area, which is effective when the load capacitance is lower than the total charge pump capacitance. The strategy relies on an unconventional pumping capacitors sizing, which set them not equal and follows a linear distribution. The approach is based on a theoretical analysis and is validated through post‐layout simulations using a 130‐nm complementary metal‐oxide semiconductor (CMOS) standard technology. The simulations demonstrate the advantages of the proposed design strategy and the accuracy of the theory.
