A device and method for converting a low voltage signal into a high voltage signal are provided, which can be implemented by using a low voltage CMOS manufacturing process to convert a low voltage signal of 0V to 1.5V into a high voltage signal of 2.5V to 1.25V. According to one preferred embodiment, PMOS transistors are employed to perform voltage level conversion and supply voltages of 1.25V and 2.5V are supplied to the PMOS transistors. During the conversion, no current path exists between the supply voltages thus effectively reducing static power consumption. In addition, the low level of the high voltage signal is outputted through the drain and source of the transistor so that the low level of the high voltage signal can be accurately defined and not affected by manufacturing parameters.
