Abstract
A circuit including an output node and a cross-coupled pair of semiconductor devices configured to provide, at the output node, an output signal in a second voltage domain based on an input signal in a first voltage domain is described herein. The circuit further includes a pull-up assist circuit coupled to the output node; and a look-ahead circuit coupled to the pull-up assist circuit, wherein the look-ahead circuit is configured to cause the pull-up assist circuit to assist in increasing a voltage level at the output node when there is a decrease in a voltage level of an inverted output signal in the second voltage domain from a high voltage level of the second voltage domain to a low voltage level of the second voltage domain.
