Abstract

A driver circuit includes a first termination resistor and a distributed amplifier comprising a plurality of pairs of input transistors and comprising inductors coupled between each pair of input transistors. The driver circuit also includes a distributed current-mode level shifter coupled to the first termination resistor. The distributed current-mode level shifter includes a first plurality of inductors coupled in series between the first termination resistor and the distributed amplifier and a first plurality of capacitive devices. Each capacitive device is coupled to a power supply node and to a node interconnecting two of the series-coupled inductors.
