Abstract:
A driver includes first and second resistors coupled to a supply voltage and coupled to pairs of main transistors at positive and negative output nodes. The first and second pairs of main transistors provide emphasis and de-emphasis on the positive and negative output nodes. The driver also includes a delay inverter, a pull up booster and a pull down booster. The delay inverter delays and inverts each of a pair of differential input signals to provide delayed and inverted differential signals. The pull up booster provides a bypass current path that bypasses the first and second resistors but includes at least some of the first and second pairs of main transistors. The pull down booster provides an additional current path from the supply voltage through the first or second resistor to ground.
