Abstract
A circuit for providing voltage level shifting in an integrated circuit includes an inverter having an input coupled to receive an input signal having a first voltage level; an output stage having a first transistor coupled in series with a second transistor, and an output node between the first transistor and the second transistor generating an output signal having a second voltage level. A gate of the second transistor is coupled to an output of the inverter. A pull-up transistor is coupled between a reference voltage having the second voltage level and a gate of the first transistor. A switch is coupled between the gate of the first transistor and the gate of the second transistor to control a voltage at the gate of the first transistor. A method of providing voltage level shifting in an integrated circuit is also disclosed.
