An ECL logic gate includes an input stage, an output stage, and a multifunction current mirror circuit. The input stage includes a plurality of input transistors, a reference transistor, and an output which indicates the relative conductivities of said reference transistor as compared to one or more of the input transistors. This output is coupled to the output stage. A current mirror circuit having first and second current paths is provided in which the input stage is coupled in series with the first current path, and the output stage is coupled in series with the second current path.
