ABSTRACT:
A level shift circuit is used to receive a low-voltage signal to generate a corresponding high-voltage signal. The circuit has a first transistor of a first type, a second transistor of a second type, a third transistor of the second type and a fourth transistor of the second type. The first transistor has a gate receiving the low-voltage signal and a source receiving a first supply voltage. The second transistor has a source receiving a second supply voltage and a drain coupled to a drain of the first transistor. The third transistor has a source receiving the second supply voltage, a drain outputting the high-voltage signal and a gate coupled to a gate of the second transistor. The fourth transistor has a source and a gate commonly coupled to receive a third supply voltage, and a drain coupled to the drain of the third transistor.
