Abstract
There is provided a voltage mode push-pull driver output stage with low power consumption and improved output return loss (ORL) suitable for various high bandwidth data transmission applications. By structuring the output stage to have tunable resistances adjustable by voltages applied to transistors, the output stage is readily adaptable to different applications requiring different resistances or impedance matching.
