一种用于电容型电荷泵的优化的电荷转移结构与方法
摘要：
本发明属于集成电路设计领域，具体为一种用于电容型电荷泵的优化的电荷转移结构与方法。本发明用于电容间的电荷转移，将前一级的电容拆分成多个电容的并联，各电容彼此独立，依次向后一级电容充电；当有电荷输入时，并联电容连接在一起形成一个大电容，接收来自前一级电容的充电。该电荷转移机制提高了电荷转移时的能量转换效率，同时增加了升压能力，以及对负载的驱动能力。
摘要（英）：

The invention belongs to the field of integrated circuit design, specifically a charger transfer structure and method for a capacitive-type charge pump. The structure and method are used for the charge transfer among capacitors, enable the capacitors at the former stage to be divided into a plurality of capacitors for parallel connection, enable all capacitors to be independent of each other, and sequentially charge the capacitors at the next stage. When there are charges being inputted, the capacitors in parallel connection are connected together to form a big capacitor, and receives the charge from the capacitors at the former stage. The structure improves the energy conversion efficiency during charge transfer, improves the boosting capability, and improves the driving capability for a load.
