摘要

在本文中，我们提出了一种用于AMOLED显示驱动IC的新型效率优化电荷泵。在我们的设计中，我们不仅提出了开关电压动态调整技术，而且利用动态偏置方法最小化开关的导通电阻，从而提高了所提出的电荷泵的效率。为了验证我们的设计，采用Nuvoton 0.35-μm 2P3M BCD工艺制作了一个电荷泵原型。实验结果表明，当负载电流分别为0mA、60mA和120mA时，电荷泵的效率比传统电荷泵分别提高了17.78%、18.46%和18.6%。

A High-Efficiency Charge Pump for AMOLED Display Driver IC

In this paper, we propose a novel efficiency-optimized charge pump for AMOLED display driver IC. In our design, we not only present a switching-voltage dynamic adjustment technique, but also utilize a dynamic biasing method to minimize the on-resistance of the switches, and improve the efficiency of the proposed charge pump. To verified our design, a prototype charge pump has been fabricated by Nuvoton 0.35-μm 2P3M BCD process. The experimental results show that when the values of load current are respectively 0mA, 60mA and 120mA, the efficiencies of our proposed charge pump are effectively improved by 17.78%, 18.46%, and 18.6% compared to the conventional charge pump.
