提出了一种使用低温多晶硅（LTPS）TFT 的低功耗电容耦合型电平转换器。所提出的电平转换器的概念是利用电容耦合效应来降低短路电流和功耗。电容耦合效应的快速开关特性降低了输入信号过渡期间的短路电流。通过仿真结果，验证了所提出的电平移位器的功耗比之前报道的交叉耦合锁存型电平移位器降低了高达 53%。
A capacitive coupling type level shifter for low power consumption using low temperature poly-Si(LTPS) TFTs is proposed. The concept of the proposed level shifter is to use capacitive coupling effect to reduce short circuit current and power consumption. The fast switching characteristic of capacitive coupling effect reduces the short circuit current during the transition time of input signal. By simulation results, it is verified that the power consumption of the proposed level shifter is reduced up to 53 %, compared to that of the previously reported cross-coupled latch type level shifter.
