Abstract
Official abstract text for this publication.
A transmission line driver including an output configured to have a load impedance is provided. The transmission line driver includes a pull-up circuit coupled in series with the output. The transmission line driver also includes a pull-down circuit coupled in series with the output. The transmission line driver includes a shunt circuit having an adjustable impedance. The shunt circuit is coupled in parallel to the output. The shunt circuit is coupled to the pull-up circuit and the pull-down circuit. The shunt circuit is configured to receive a shunt control signal to adjust the adjustable impedance to provide linear control of an output swing at the output.
