Abstract:
A line driver for coupling a data transceiver to a line, comprising:a first amplifier having a first input and a second input and a first output coupled to a first side of the line, the first input being coupled to a first input terminal; a second amplifier having a third input and a fourth input and a second output coupled to a second side of the line, the third input being coupled to a second input terminal; a first voltage feedback resistor, having a first voltage feedback resistance, connected between the first output and the second input; a second voltage feedback resistor, having a second voltage feedback resistance substantially equal to the first voltage feedback resistance, connected between the second output and the fourth input; a series resistor, having a series resistance, and having a first series resistor side coupled to the first output and a second series resistor side coupled to the second output; a gain resistor having a first gain resistor side connected to the second input and a second gain resistor side connected to the fourth input; a first current feedback resistor, having a first current feedback resistance, connected between the first side of the gain resistor and the first side of the series resistor; and a second current feedback resistor, having a second current feedback resistance substantially equal to the first current feedback resistance, connected between the second side of the gain resistor and the second side of the series resistor.
