    • Described herein is a voltage compensated level-shifter with nearly constant duty cycle and matching rise and fall slopes of the output of the level-shifter, no meta-stability, and nearly constant propagation delay across power supply levels. The voltage compensated level-shifter comprises a first inverter to receive an input signal for level shifting from a first power supply level to a second power supply level, and to generate a first inverted signal, the first inverter operating on the first power supply level; a second inverter to receive the input signal and to generate a second inverted signal, the second inverter operating on the second power supply level; and a NOR logical gate to receive the first and second inverted signals and to generate an output signal, the NOR logical gate operating on the second power supply level, wherein the output signal is level shifted to the second power supply level.
    • 这里描述的是电压补偿电平移位器,其具有几乎恒定的占空比并且匹配电平转换器的输出的上升和下降斜率,没有元稳定性以及跨供电电平几乎恒定的传播延迟。 电压补偿电平转换器包括:第一反相器,用于接收用于从第一电源电平到第二电源电平的电平转换的输入信号;以及产生第一反相信号,所述第一反相器在第一电源电平上工作; 第二反相器,用于接收所述输入信号并产生第二反相信号,所述第二反相器在所述第二电源电平上工作; 以及NOR逻辑门,用于接收第一和第二反相信号并产生输出信号,NOR逻辑门在第二电源电平上工作,其中输出信号电平移位到第二电源电平。
