Abstract
A circuit includes a first power node that carries a first supply voltage having a first voltage level and a second power node that carries a second supply voltage having a second voltage level less than the first voltage level. A voltage driver has a first plurality of transistors, an input node for an input signal, and an output node, and a current driver has a second plurality of transistors. The current driver injects or extracts an adjustment current into or out of the output node. The first plurality of transistors and the second plurality of transistors electrically couple the output node and the current driver to the first power node in response to the input signal being at a first logic state, and electrically decouple the output node and the current driver from the first power node in response to the input signal being at a second logic state.
