Abstract
A device voltage shifter includes a first voltage reference node, a second voltage reference node, an output node and a clamp node. A first high-voltage switching transistor of the voltage shifter has a first conduction terminal coupled to the first voltage reference node and a second conduction terminal coupled to the clamp node. A second high-voltage switching transistor of the voltage shifter has a first conduction terminal coupled to the clamp node and a second conduction terminal coupled to the second voltage reference node. A third high-voltage switching transistor of the voltage shifter has a first conduction terminal coupled to the first voltage reference node, a control terminal coupled to the clamp node, and a second conduction terminal coupled to the output node. A voltage regulator of the voltage shifter is coupled between the output node and the clamp node.
