摘要
本文旨在使用低温多晶硅氧化物（LTPO）电平降低转换器（LDS）来转换在不同频率下工作的不同幅度的电压信号。LTPO LDS 由 p 型低温多晶硅和 n 型 a-InGaZnO 薄膜晶体管组成。输入电压范围为 2 V~10 V，可转换为 1.2 V~4.41 V 的输出电压。在 50 kHz 的工作频率下，上升和下降时间小于 400 ns。此外，只需 10 V 单电源，即可为接口电路提供 6 V、3 V 和 1.8 V 的多路输出电源。
High Speed Level-Down Shifter Using LTPO TFTs for Low Power and Interface Electronics
This article intends to use a low-temperature poly-Si oxide (LTPO) level-down-shifter (LDS) to translate voltage signals with different amplitudes operating at various frequencies. The LTPO LDS is made of p-type low-temperature poly-Si and n-type a-InGaZnO thin-film transistors. The input voltage range of 2 V~10 V could be shifted to 1.2 V ~ 4.41 V output voltage. The rising and falling times are less than 400 ns at the operational frequency of 50 kHz. Also, the multiple output power supply of 6 V, 3 V, and 1.8 V for interface circuits has been possible with a single supply of 10 V. The proposed LDS shows a switching power consumption of 95.57 pW and area of 0.023 mm2.
