Patent attributes
The line driver circuit is provided that includes a first pull-up variable resistor connected between a first power supply and the first output terminal, a second pull-up variable resistor connected between the first power supply and the second output terminal, a first pull-down variable resistor connected between a second power supply and the first output terminal, a second pull-down variable resistor connected between the second power supply and the second output terminal, a floating variable resistor connected between the first output terminal and the second output terminal, and coder logic to adjust an output voltage across the first output terminal and the second output terminal by varying a resistance of one or more of the floating variable resistor, the first pull-up variable resistor, the second pull-up variable resistor, the first pull-down variable resistor, and the second pull-down variable resistor in response to received data bits.
