Abstract:
A dual-level voltage shifter, comprising:a first branch comprising first, second, third, and fourth transistors connected in series between a first node and a second node, the first and fourth transistors configured as diodes, and the gates of the second and third transistors connected to each other; a second branch comprising fifth and sixth transistors, and a third section comprising seventh and eighth transistors, the second and the third sections each connected in series between a third node and a fourth node; a pass gate connected between a node defined between the second and third transistors, and between the seventh and eighth transistors; a node defined between the second and third transistors, and connected to the gates of the fifth and sixth transistors; and the gates of the seventh and eighth transistors connected to a node defined between the fifth and sixth transistors.
