US Patent 7443211 Transmitter and transmission circuit

Transmitter and transmission circuit. For realizing a differential transmitter, a switch circuit is connected between two load transistors of two complementary MOS pairs. The switch circuit can have two inductors. When the two complementary MOS pairs are conducting current to drive signal transition at output nodes, the inductors open to make the load transistors stop draining current. Also, the switch circuit can have switch transistor controlled by an edge detector for detecting raising and falling edges of the input signals, such that the switch circuit can make the load transistors stop draining current accordingly. In this way, raising and falling edges of the output signals are emphasized to improve signal propagation.
