ABSTRACT:
A semiconductor integrated circuit having an emitter follower circuit coupled with an output of a logic circuit includes the following. A first emitter follower circuit receives an output signal of a logic circuit such as an emitter coupled logic circuit. An output signal obtained at an emitter output of the first emitter follower circuit forms a finalized output signal of the logic circuit. A second emitter follower circuit receives a signal in phase with the output signal of the logic circuit. A detecting circuit detects a difference in level between the output signal of the first emitter follower circuit and an output signal of the second emitter follower circuit. A driving circuit drives a load capacitance coupled with the emitter output of the first emitter follower circuit during a period when the detecting circuit detects the difference.
