Abstract
A level shifter circuit is provided. In some examples, the level shifter circuit includes a first set of transistors and a second set of transistors coupled between first and second power supply nodes. The control terminals of the first and second lower transistors are coupled to an input node. The level shifter circuit also includes a third set of transistors and a fourth set of transistors coupled between first and third power supply nodes. A control terminal of a third lower transistor is coupled to a second intermediate node, and a control terminal of a fourth lower transistor is coupled to a first intermediate node. Control terminals of the first upper transistor and the fourth upper transistor are coupled to a third intermediate node. Control terminals of the second upper transistor and the third upper transistor are coupled to a fourth intermediate node.
