Abstract

A circuit for controlling output swing in a current-mode logic circuit is described. The circuit comprises a plurality of current-mode logic circuits coupled in series; a first current-mode logic circuit of the plurality of current-mode logic circuits coupled to provide a signal to a second current-mode logic circuit of the plurality of current-mode logic circuits; an amplitude detector coupled to detect an amplitude of the signal received at the second current-mode logic circuit; and a control circuit coupled to the amplitude detector; wherein the control circuit generates an amplitude control signal for a current-mode logic circuit of the plurality of current-mode logic circuits based upon a detected amplitude of the signal received at the second current-mode logic circuit. A method of controlling output swing in a current-mode logic circuit is also disclosed.
