Abstract
A voltage level converter includes a static voltage level converter and a split-level output circuit coupled to the static voltage-level converter. In another embodiment, the voltage-level converter includes a static voltage level-converter, a first transistor, and a second transistor. The static voltage-level converter includes an input node, a first pull-up node, a second pull-up node, an inverter output node, and an output node. The first transistor is coupled to the input node and the first pull-up node. The second transistor is coupled to the second pull-up node and the inverter output node.
