  • Patent number: 4754171
    Abstract: A current-mode logic circuit includes a pair of input bipolar transistors coupled in the emitter-coupled single differential circuit configuration, one of which input transistors is connected at its base to receive an input signal and the other input transistor is connected at its base to receive a reference voltage. The collector of each of the input transistors is connected to a base of an emitter-follower driver which is in turn connected at its collector to a voltage supply terminal and at its emitter through load means to another voltage supply terminal. The emitters of these output transistors are connected to a pair of output terminals to generate a pair of complementary logic signals. Further, there are provided first and second auxiliary transistors connected in the cross-coupled flip-flop configuration and connected at their collectors to the emitters of the first and second output bipolar transistors, respectively.
