Abstract
In one example, a current-mode logic (CML) circuit includes a differential transistor pair having a differential input port configured to receive a differential input voltage, a bias port configured for coupling to a current source, and a differential output port. The CML circuit further includes a load circuit coupled to the differential output port. The load circuit includes an active inductive load, a cross-coupled transistor pair, and a switch coupled between the cross-coupled transistor pair and the differential output.
