Abstract:
1. A driver for communicating data at a rate exceeding about several hundred mega bit per second, the driver comprising: circuitry comprising an output couplable to a load, and a first, second, third and fourth current source, wherein the circuitry outputs from the output a low voltage differential signal having a first current sourced from the first and second current source for driving the load from a first voltage at a first time to a second voltage at a second time; and a current-sourcing module for applying a second current to the output at a third time, wherein the third time occurs about the first time, wherein the second current combines with the first current to reduce a duration between the first time and the second time as compared to the first current alone, and wherein the current-sourcing module is communicatively coupled to drain terminals of the first and second current sources and coupled to drain terminals of the third and fourth current sources, and coupled to a reference voltage.
