Abstract
An amplifier stage is provided for supplying differing currents to integrated injection logic I.sup.2 L circuits. The amplifier stage has a current hogging injection logic input CHIL gate, at least one further gate, and a CHIL output gate. Each of the gates has an injecting emitter, an output and an input. First I.sup.2 L circuits connected to a first injector path connect with the input of the CHIL input gate. Second I.sup.2 L circuits having a second injector path connect with an output of the CHIL output gate. The gate provided between the input and output CHIL gates is provided as a single I.sup.2 L gate, dual I.sup.2 L gates, or the combination of an I.sup.2 L gate and a CHIL gate.
