LEVEL SHIFTING CIRCUIT OF SEMICONDUCTOR DEVICE

摘要

A level shifting circuit for a semiconductor device is provided to efficiently generate first and second power voltages and a ground voltage by using transistors functioning as switches. A controller(100) changes the phase of a power converting input signals. A level shifting unit(200) increases/decreases the level of an input signal by using two level shifters to output a level shift output signal. A driving unit(300) amplifies the level shift output signal to output a power voltage output signal.
