Abstract
A system and a method for communicating data at a rate exceeding about a gigabit per second is described. The system may include circuitry and a current-sourcing module. The circuitry may include an output couplable to a load. The circuitry may output from the output a low voltage differential signal having a first current that drives the load from a first voltage at a first time to a second voltage at a second time. The current-sourcing module may apply a second current to the output at a third time, which occurs
Claims34
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, wherein the circuitry outputs from the output a low voltage differential signal having a first current 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.
A method for communicating data at a rate exceeding about a gigabit per second, comprising:
- outputting, from an output of circuitry couplable to a load, a low voltage differential signal having a first current for driving the load from a first voltage at a first time to a second voltage at a second time;
- and
- applying a second current to the output at a third time, wherein the third time occurs about the first time.
A driver for communicating data at a rate exceeding about a gigabit per second, the driver comprising:
- circuitry comprising a first, second, third, and fourth switches arranged in a bridge configuration and an output couplable to a load, wherein the first and the second switches cause the output to provide a first low voltage differential signal having a first current for driving the load from a first voltage at a first time to a second voltage at a second time, and wherein the third and the fourth switches cause the output to provide a second low voltage differential signal having a second current for driving the load from a third voltage at a third time to a fourth voltage at a fourth time;
- and
- a current-sourcing module for applying a third current to the output at about the first time and for applying a fourth current to the output at about the second time.
