摘要

本文提出了一种有助于实现低功耗LCD列驱动器的混合级电荷回收方案。该方案消除了传统方法对极性反转电路的需要，简化了控制。还描述了另一种将两个外部电容器合并为一个的技术。这使得柱式驱动集成电路的多级回收操作更加实用。

A hybrid-level multi-phase charge-recycler with reduced number of external capacitors for low-power LCD column drivers

This paper presents hybrid-level charge recycling scheme which can be helpful in implementing low power LCD column drivers. The proposed scheme eliminates the necessity of polarity reversing circuit of the conventional method, simplifying the control. Another technique which merges two external capacitors into one is also described. This makes the multi-level recycling operation in column driving IC more practical.
