The charge adjusting decreases the wall voltage by applying an increasing voltage that increases continuously or step by step.

Abstract: An apparatus for high speed signal propagation across a net in an integrated circuit operates with a driver that is coupled to the net, for driving signals across the net. A first transition assist driver (TAD) is coupled to a first node in the net and is capable of pulling the voltage level of the first node in response to the voltage level of the first node reaching a threshold value. The threshold value can be adjusted in order to increase the switching speed or, alternatively, the noise immunity of the first TAD. A second TAD is coupled to a second node in the net and is capable of pulling the voltage level of the second node in response to the voltage level of the second node reaching the threshold value. The apparatus is used for increasing the propagation speed of signals that are transmitted in a microprocessor block or other stages in an integrated circuit.
