Abstract
Methods and apparatus to reduce propagation delay of circuits are disclosed. A disclosed apparatus to reduce propagation delay of a circuit comprises a level shifter to selectively turn a first circuit on and off; a first switch to couple the first circuit to a second circuit when the first circuit is on, wherein the second circuit is to selectively receive a first current from the first circuit based on a signal the second circuit receives from the level shifter; and a second switch to couple the first circuit to a reference signal based on the first current, the second switch causing the first circuit to start to turn off.
