Abstract

The voltage level shifter includes a first voltage shift circuit, a second voltage shift circuit, a first switch circuit, a second switch circuit, a third switch circuit and a fourth switch circuit. The first voltage shift circuit receives a first input voltage, and the second voltage shift circuit receives a second voltage shift circuit. When the first voltage is high level voltage, a second output voltage and a first voltage are transformed to a ground voltage so as to open the second switch circuit and the fourth switch circuit, and then the first output voltage is transited to a system voltage. When the second voltage is high level voltage, a first output voltage and a second voltage are transited to a ground voltage so as to open the first switch circuit and the third switch circuit, and then the second output voltage is transited to the system voltage.
