Abstract: A low-power high-swing current-mode logic (CML) driver circuit includes a first differential-pair and a second differential-pair. The first differential-pair includes first transistors, and is coupled to a first voltage supply that supplies a first voltage. The second differential-pair includes second transistors, and a common node of the second differential-pair is coupled to a second voltage supply. The second voltage supply supplies a second voltage that is higher than the first voltage. Control terminals of the first transistors are coupled to control terminals of the second transistors to form input nodes of the driver circuit.
