摘要： A current boost circuit acts as an “eye opener” for a digital bus line. A controlled current injects a fraction of the normal signaling current magnitude from a source driver onto the bus line, after a transition between the two logical states on the bus line is detected. The duration of the additional current injection is a fraction of the unit interval. In one embodiment, a linear system uses the summation of a proportional boost current and a delayed and negated proportional boost current. In another embodiment, a positive or negative edge detection circuit triggers a monostable pulse generator that controls the injection of short bursts of additional current into the bus lines. In some embodiments the boost current is suppressed when the bus line is driven from a driver other than the source driver.
