 Wide supply range high speed low-to-high level shifter patent thumbnailnew patent Wide supply range high speed low-to-high level shifter
A level shifter may include a first current source configured to source current to a node that pulls up an output voltage of the level shifter to a logic high level and a second current source configured to sink away current from the node to pull down the output voltage to a logic low level. When the output voltage at the node reaches the logic high voltage, the first current source may be deactivated while a latch connected to the node maintains the output voltage at the logic high level.
