Line precharging circuits and methods. |
摘要 |
<p>A bus precharge circuit is provided that precharges a bus line or node as an inverse function of the precharge level already attained on the bus line, such that the precharge level on the bus line is gradually approached. The precharge circuit charges the bus line to a midpoint between high and low logic states. The preexisting state of the bus line is stored and is used to select one of two voltage supplies to which the bus line may be partially pulled up or down. The switchpoint of a precharge circuit sensing gate is set to be equivalent to the switchpoint of the receiving gate of receiver on the bus line. <IMAGE></p> |
