Abstract:
A driver circuit receiving power at a first potential from a first power supply and power at a second potential from a second power supply, receiving an input signal having a first level and a second level, and supplying a complementary signal, responsive to the input signal, to a signal transmission line pair having a first signal transmission line and a second signal transmission line, the first signal transmission line and the second signal transmission line being mutually parallel and of equal length, wherein:the driver circuit closes a first current path between the first power supply and the first signal transmission line, and a second current path between the second power supply and the second signal transmission line, when the input signal is at the first level; and the driver circuit opens the first current path and the second current path, and closes a third current path between the first power supply and the second power supply, bypassing the signal transmission line pair, when the input signal is at the second level.
