Abstract: The present invention provides a voltage shifter circuit, in which a control circuit is used to control the pull-up circuit, so that the pull-up circuit is kept as off when the signal from the input signal source changes from a low voltage to a high voltage. Hence, the competition between the pull-up circuit and the pull-down circuit is avoided. The speed of the voltage shifter circuit is improved and the voltage shifter circuit can operate within a wider voltage range. The delay time of the pull-up circuit and the pull-down circuit is small and the duty cycle is small. In addition, since no direct current path is established, no current is wasted. Additionally, the voltage shifter circuit uses the second delayer to compensate the delay time between the pull-up circuit and the pull-down circuit and optimizes the duty cycle.

In response to the input signal falling below the higher threshold, the first logic value is output, and maintained at the first logic value, until the input falls below the lower threshold and thereafter rises above the lower threshold.
