Abstract
A level shifter that includes: a power supply system current source; a second transistor having a third main electrode that is connected to an input voltage signal terminal, a fourth main electrode that is connected to an output voltage signal terminal, and a second control electrode that is connected to a third power supply voltage having a voltage that is lower than a first power supply voltage and higher than a second power supply voltage; a second resistor; and a third transistor having a fifth main electrode that is connected to the second end of the second resistor, a sixth main electrode that is connected to the second power supply voltage, and a third control electrode that is connected to a first control electrode of a first transistor of the power supply system current source.
